SUMMARY

We present here our research on the presence of graphene in covid vaccines. We have carriedout a random screening of graphene-like nanoparticles visible at the optical microscopy inseven random samples of vials from four different trademarks, coupling images with theirspectral signatures of RAMAN vibration.
By this technique, called micro-RAMAN, we have been able to determine the presence ofgraphene in these samples, after screening more than 110 objects selected for their graphenelike appearance under optical microscopy. Out of them, a group of 28 objects have been
selected, due to the compatibility of both images and spectra with the presence of graphene
derivatives, based on the correspondence of these signals with those obtained from standards
and scientific literature. The identification of graphene oxide structures can be regarded asconclusive in 8 of them, due to the high spectral correlation with the standard. In theremaining 20 objects, images coupled with Raman signals show a very high level ofcompatibility with undetermined graphene structures, however different than the standard
used here.
This research remains open and is made available to scientific community for discussion. We
make a call for independent researchers, with no conflict of interest or coaction from any
institution to make wider counter-analysis of these products to achieve a more detailed
knowledge of the composition and potential health risk of these experimental drugs, remindingthat graphene materials have a potential toxicity on human beings and its presence has notbeen declared in any emergency use authorization.

1. ANALYTICAL METHODOLOGY
1.1. Fundamentals of the micro-Raman technique
Due to the characteristics of the sample and to the dispersion of objects with agraphene appearance of micrometric size in a complex matrix of indeterminate
composition, the direct application of spectroscopic methods does not allow
characterization of the nanoparticles studied here without a previous microscopic
localization or fractionation from the original sample. Therefore, microscopy coupled
to RAMAN spectroscopy (micro- RAMAN) was selected as an effective technique for an
exhaustive screening of micrometric objects visible under the optical microscope.
RAMAN infrared spectroscopy is a fast, non-destructive technique that allows theverification of the structure of this material by identifying vibrational modes andphonons generated after excitation with monochromatic laser, generating inelastic
dispersion that manifests itself in peaks of infrared emission that are a characteristic
signature of the reticular structure of graphene and derivatives. Coupled optical
microscopy allows the excitation laser to be focused on specific objects and points
located on objects, to reinforce the degree of confidence in identifying the nature of
the material, and to obtain complementary information on thickness, defects, thermal
conductivity and edge geometry of graphene nanocrystalline structures.

1. NANOCRYSTALLINE STRUCTURE BANDS-G-band (~1580-1600 cm-1): Indicates a permissible phonon vibration (elementary
vibration of the net) in the plane of the aromatic ring (sp2 hybridization), characteristicof the crystalline structure of graphite and graphene. It presents a red shift (lower
frequency, in cm-1), as well as higher intensity with a higher number of layers. On thecontrary, the higher energy in doped graphene shows as a blue shift (higher frequency
in cm-1), along the 1580-1600 cm-1 range (Ferrari et al, 2007).
-2D band (~2690 cm) (or G'): Indicates stacking order. It depends on the number oflayers, it does not depend on the degree of defects, but its frequency is close to twicethat of peak D. Its position oscillates according to the type of doping. The presence of
single-layer graphene (SLG) has been associated with the presence of an isolated andsharp 2D peak, increasing in width according to the number of layers (Ni et al., 2008).
- The ratio of I2D/IG is proportional to the number of layers of the graphite network.
- In graphite G and 2D appear are sharper and narrower than in graphene.

In graphene oxides (GO) the disorder comes from the insertion of hydroxyl (-OH) andepoxide (-O-) groups.
-D band (~1340 cm-1). It shows the density of defects in the crystal network due tofunctionalization, doping or structural anomalies generating holes or new sp3 (C-C)

3. RESULTS AND DISCUSSION(See images and spectra of the selected objects in Annex 3: RESULTS)
The micro-Raman technique applied here has proved to be very effective for the rapid
screening of a large number of microscopic objects in the detection of graphene microstructures dispersed in complex samples. Compared to macro-Raman spectroscopy ofwhole aqueous dispersions, the combination with microscopy in micro-Raman has theadvantage of allowing the association of spectral fingerprints to nanoparticles visible
under the optical microscope. This technique allowed us to focus the prospection
towards specific objects with graphene-like appearance, reinforcing their spectroscopic
characterization with coupled images. In this work, the preliminary selection of objects
has focused on two typologies, translucent sheets and opaque carbonaceous objects,
due to their visual similarity with similar shapes observable in standards after
sonication or in graphene oxide dispersions (see Annex 3 Results). The difference
between both typologies is not due to their chemical composition, both derived fromgraphite, but only to the degree of exfoliation of the starting graphitic material and thenumber of superimposed layers, assuming a threshold of around 10 layers as areference limit to consider that a material graphite (3D) (Ramos-Fernandez, 2017).
Anyhow, it was out the scope of our work to further characterize these structures.
A total of 110 objects with graphene-like appearance were selected, mostly located at
the edge of the sample droplets after dehydration, inside or outside of the dragging
area by drying at room temperature of the original aqueous phase. Our of them,another 28 objects in total were selected for their higher degree of spectral
compatibility with graphene materials reported in the literature, considering both
spectra and images. The images and RAMAN spectra of these objects are shown in the
Annex 3 of this report. It is of interest to note that the samples do not dry completely
at room temperature, always leaving a gelatinous residue, whose limit can beobserved in some of the photographs shown. The composition of this medium is
unknown for the moment as it was not the subject of the present study, as well as thatof other typologies of micrometric size objects that could be observed recurrently inthe samples at low magnification (40-600X). The Raman spectra of some of theseobjects were obtained but are not shown in this study because they did not present
visual resemblance to graphene or graphite.
A limitation in obtaining defined spectral patterns with this technique has been theintensity of the fluorescence emitted by many selected objects. In numerous
translucent sheets with a graphene appearance, it was not possible to obtain Raman
spectra free of fluorescence noise, so the technique did not allow to obtain specific
RAMAN signals with well-defined peaks in many of them. Therefore, in these objects
the presence of graphene structures can neither be affirmed nor ruled out. Anotherlimitation of the micro- RAMAN technique is the low quality of the optical image of theequipment, which often prevents the detection of high-transparency graphene-likesheets, which can, however, be observed in optical microscopes with proper condenser

adjustment. For these objects an effective alternative for characterization would be touse other complementary microscopy techniques coupled with spectroscopy, such as
XPS with good optics or the obtention of electron diffraction pattern of graphene byelectronic microscopy (TEM).
Considering these selection criteria, the 28 objects found with potential graphene
identity have been distributed in 2 groups, according to the degree of correlation with
the RAMAN spectrum of reduced graphene oxide pattern used (rGO, TMSIGMA
ALDRICH). GROUP 1 included 8 objects whose spectral patterns were similar to thespectrum of the rGO pattern, and therefore the presence of graphene oxide (nº 1-8)
can be affirmed with certainty. This spectral correspondence can be consideredunequivocal and is characterized by 2 dominant peaks in the scanned range (between
1200-1800 cm-1), peaks called G (~1584 cm-1) and D (~1344 cm-1), characteristic ofgraphene oxides. This characterization by spectral correspondence between the signalsof these nanoparticles and the rGO pattern is f u r t h e r reinforced by the
microscopic appearance of these objects, all of them with an opaque carbonaceous
appearance similar to that of the standard objects, as can be seen in the photographs in
the Results annex. Therefore, we can affirm with a high level of confidence that theidentification of graphene material in all the analyzed samples of Group 1 IS
CONCLUSIVE, and with high probability graphene oxide structures can be assigned tothese nanoparticles. These group 1 objects presented a micrometric size in ranges oftens of microns (shown as a blue line in photographs of some of them).
In the second group of 20 objects (GROUP 2, nº 9-28), RAMAN signals compatible withthe presence of graphene or graphitic structures have been detected, showing peaksof RAMAN vibrations around the G band (1585-1600 cm-1), compatible with the G
peak of the nanocrystalline structure of graphene or graphite. This vibrational mode is
generated by the allowed vibration of the phonon in the plane of the aromatic ring(sp2). Its drifting towards higher frequencies in some objects, tending towards 1600 cm1 (blue shift) can be assigned to a wide variety of modifications referred extensively inthe literature, such as, for example, the number of graphene layers or doping withfunctional groups or heavy metals others (Ferrari et al, 2007). Visually, this group
includes the two types of appearances observed in the standards: whether opaquemicrometric objects with a carbonaceous appearance (nº 9, 11, 16, 21, 22, 23, 24,
25, 26, 27 and 28) or translucent sheets with graphene-like appearance (nº 10,
12, 13, 14, 18, 19 and 20).
In the spectra of this group 2, the G peak maxima are accompanied by other dominantpeaks of non-determined assignment in this work. A subgroup (2.1.) can be madefrom of objects whose spectra have the two 2 dominant peaks located in band ranges
that could be assigned to the two main vibrational modes of graphene oxide, G (range
1569-1599 cm-1) and D (range 1342-1376 cm-1) (objects no. 11, 14, 15, 16, 17, 20, 21,
22, 23, 24, 25 and 26). Considering both microscopic images and RAMAN signals
together, the assignation of the spectra of this group 2.1 to graphenic structures canbe done with a high level of confidence. However, although the structuralmodifications of the network generating spectral signals different than the standard

rGO used have yet to be determined.
The signals from a second subgroup (2.2) of objects of this Group 2 (nº 9, 10, 12, 13,
18, 19, 25, 27, 28) can be considered compatible with the presence of graphene
structures due to the presence of maxima in the G-band, although the use of moredetailed spectral analysis algorithms would be necessary, since no clear peaks that
could be assigned to the vibrational mode D, around 1344 cm-1 in the rGO standard,
were not clearly observed. However, the presence of peak D is not a sine qua non
condition for the assignment of graphene structures to spectra, and in consequence theseobjects have been selected for this report as they are showing compatible vibrational
maxima in the vicinity of the G-band (range 1569-1600 cm-1). There is still an open
debate about the interpretation of this D-band and its variable frequency and shape(Ferrari and Robertson, 2004). As outlined in the methodological introduction, theintensity of the D peak, generally cited around 1355 cm-1, as well as the intensity ratiowith the G peak (ID / IG) is indicative of the degree of disorder in the graphene
network, introduced by different agents such as doping, introduction of very different
functional groups or breaks in the continuity of the network. In ordered graphitic
materials this peak D is absent. In some spectra of this subgroup 2.2., other peaks withhigher frequencies (blueshift) than the standard appear, whose assignment tovibrational mode D is possible, although this assignment is yet to be determined byprocessing with algorithms analysis which was beyond the scope of the present work.
Therefore, at present, for these spectra we can only state that the absence or drifting(shift) of the D peak with respect to the location of the rGO pattern still requires a
structural interpretation according to the models available. According to theliterature, both the variations in the shift of the G and D peaks, as well as their variablewidth and intensity, and the presence of other peaks seen in these spectra could be
due to very diverse modifications yet to be determined, including different degrees ofdisorder, oxidation, doping, functionalization, and structural breaks. The study ofthese modifications were beyond the scope of this report.
Complementary to the range 1200-1800 cm-1, when RAMAN spectroscopy was
extended up to 2800 cm-1 for some objects (nº 3, 8 and 11), a 2D peak of low intensityand frequency amplitude was detected, being absent in other scanned objects (datanot shown). However, both in the rGO standard and some objects with G peak maxima,
the intensity of this peak was always been very low compared to the G and D peaks ofthe spectra. This might be due to the fact that, in graphene oxides, the relative
intensity of the 2D peak (~2700 cm-1) with respect to the G and D peaks is greatly
reduced. Therefore, in this study we have dispensed generally with analyzing the 2D
peak for reasons of greater efficiency and use of limited resources required to scan as
many objects as possible within a limited amount of time. In future work, it would beof interest to examine it for all objects, thus estimating the ratio of I2D/2G intensities inthose objects where it minimally manifests in this vibrational mode, which would allow
for estimates to be made about the number of layers of the structure.

The objects shown in this study represent a minority portion of the total micrometricobjects visible at low magnification in light-field optical microscopy (100X). These
objects were scanned and are not shown in this study because their spectra where notcompatible with graphene structures as they lack a band that could be assigned to G
vibrational mode peak. It is of great interest to note that many of these objects show
RAMAN maxima in the 1439-1457 cm-1 band. Likewise, among the objects in group 2.2,
also a prominent peak is frequently found in this band, around 1450 cm-1, in
combination with peaks G and D (nº 11, 12, 14, 15, 16, 17, 20, 21, 23, 24, 25, 26 and28). The assignment of this band around 1450 cm-1 is still pending, since it does notcorrespond to specific peaks in graphene, but we consider it to be of great importancefor the knowledge of the composition of the samples due to the frequent appearanceof this vibrational mode. As a working hypothesis, this band is usually assigned toorganic methylene groups -CH2- by bending the pair of hydrogens- (scissoring).
However, it has also been referred to as a band of moderate intensity associated witharomatic rings, and if so, it could also be associated with graphene (Ferrari andRobertson, 2004). As stated, another possible assignment of this band would be thatof a superimposed vibrational mode of some compound other than graphene, more
likely, or even of the hydrogel medium remaining after drying, as in all samples there
is always a viscous residue remaining after drying at room temperature. This residue
could in many cases be manifesting RAMAN vibrations overlapping with the objects thatremain embedded in it, but not in those that appear outside the gel at the limits of thedrying drag zone. In this sense, it is possible that this vibrational mode of the medium
appears overlapped with the G and D peaks of graphene in the spectra of subgroup
2.1. It is beyond the scope of this work to characterize this medium, as well as all thecomponents of the sample. However, there are some substances capable of forming
this hydrogel matrix whose RAMAN signals show prominent vibrational modes aroundthis band, such as polyvinyl alcohol (PVA), methylacrylamide, or the polymer PQT-12(Mik Andersen, https://corona2inspect.blogspot.com/ pers. com). It is also a fact thatsome of these substances have been combined with graphene in experimental
biomedicine designs that can be found in the scientific literature, for example artificial
synapses for PQT-12 (Chen and Huang, 2020), gelatins for neuronal regeneration
combining methylacrylamide with graphene (Zhu et al, 2016) or PVA/GO electrospun
fibers (Tan et al, 2016). Now, all these hypotheses about the assignment of this peakin the vicinity of 1450 cm-1 remain open.
In conclusion, out of a total of 110 scanned objects, unambiguous signals for thepresence of graphene oxide have been found in 8 objects, and signals compatible
with the presence of graphitic or graphene structures in another 20 objects. The restof the objects scanned here, out of 110 nanoparticles with graphene-like appearance
have not shown signals compatible with graphene, with spectra at times dominated byexcess noise caused by excessive fluorescence intensity, so we cannot neither assign
nor rule out the presence of graphene structures in them.
As a continuation of this line of work, and although our micro-RAMAN analysis has

shown conclusive signs of the presence of objects with graphene structure, toconsolidate the certainty of identification and to deepen the structuralcharacterization, it would be convenient to carry out complementary analyses using
coupled microscopy and spectroscopy techniques such as XPS spectroscopy, or TEM
electron diffraction.
For the present investigation, most of the samples have been obtained from sealed
vials. Also, during the extraction of the samples and their transfer to slides for Raman
microscopy, we worked under aseptic conditions under laminar flow chamber.
However, the possibility of sample contamination processes during manufacturing,
distribution, and processing, as well as the general applicability of these findings tocomparable samples, need to be assessed by routine and more extensive monitoringof similar batches of these products.
Although the results of this sampling are conclusive with regard to the presence ofgraphenic structures in some samples analyzed, this research is considered open forcontinuation and is made available to the scientific community for replication andoptimization, considering it necessary to continue with a more detailed and exhaustive
spectral study, based on a statistically significant sampling of similar vials, and theapplication of complementary techniques to confirm, refute, qualify or generalize theconclusions of this report. The samples analyzed are duly guarded and available for
future scientific collaboration.

CONCLUSIONS
A random sampling of COVID19 vaccine vials has been performed using a coupledmicro-RAMAN technique to characterize graphene-like microscopic objects using
spectroscopic fingerprints characteristic of the molecular structure.
The micro-RAMAN technique allows to reinforce the level of confidence in theidentification of the material by coupling imaging and spectral analysis as observational
evidence to be considered together.
Objects have been detected whose RAMAN signals by similarity with the standard
unequivocally correspond to GRAPHENE OXIDE.
Another group of objects present variable spectral signals compatible with graphene
derivatives, due to the presence of a majority of specific RAMAN signals (G-band) thatcan be assigned to the aromatic structure of this material, in conjunction with its
visible appearance.
This research remains open for continuation, contrasting and replication. Further
analyses based on significant sampling, using the described technique or others which
are complementary would allow us to assess with adequate statistical significance thelevel of presence of graphene materials in these drugs, as well as their detailed chemicaland structural characterization.
