UNASSIGNED: Synthesis of @entity575 nanoparticles (AgNPs) has become a necessary field of applied science. Biological method for synthesis of AgNPs by Rhizopus stolonifer aqueous mycelial extract was used. The AgNPs were identified by UV-visible spectrometry, X- @entity16039 diffraction (XRD), transmission electron microscopy (TEM) and Fourier transform infrared spectrometry (FT-IR). The presence of surface plasmon band around 420  nm indicates AgNPs formation. The characteristic of the AgNPs within the face-centered cubic (fcc) structure are indicated by the peaks of the X- @entity16039 diffraction (XRD) pattern corresponding to (1  1  1), (2  0  0) and (2  2  0) planes. Spherical, mono-dispersed and stable AgNPs with diameter around 9.47  nm were prepared and affirmed by high-resolution transmission electron microscopy (HR-TEM). Fourier Transform Infrared (FTIR) shows peaks at 1426 and 1684  cm(-1) that affirm the presence of coat covering protein the AgNPs which is known as capping proteins. Parameter optimization showed the smallest size of AgNPs (2.86      0.3  nm) was obtained with 10(-2)  M @entity4673 at 40    C. The present study provides the proof that the molecules within aqueous mycelial extract of R. stolonifer facilitate synthesis of AgNPs and highlight on value-added from R. stolonifer for cost effectiveness. Also, eco-friendly medical and nanotechnology-based industries could also be provided. Size of prepared AgNPs could be controlled by temperature and @entity4673 concentration. Further studies are required to study effect of more parameters on size and morphology of AgNPs as this will help in the control of large scale production of biogenic AgNPs.
