Nonthermal Atmospheric Pressure Plasmas: Generation, Sources and Applications Nonthermal atmospheric pressure plasmas, also known as Cold Atmospheric Plasmas (CAPs) are emerging as a potential alternative for cancer treatment since they can be generated at atmospheric conditions and their low temperatures allow the interaction with living tissues without thermal damage. This article focus on the study of the interaction between plasma and a noncancerous cell line, particularly, VERO cells. Some invitro experiments were performed with a custommade device in order to better understand how CAPs affect noncancerous cells. It was also studied the influence of several factors such as the distance from the device (gap), the duration and the type of treatment, direct or indirect, on the cell viability after exposure to CAPs treatments. The obtained results revealed the importance of the determination of the optimal relation between gap and treatment time, since small variations in each one of them can lead to different results in the cell viability.

Effect of Epigallocatechin3gallate on DMPC Oxidation Revealed by Infrared Spectroscopy The daily exposure of skin cells to the sun increases the rate of production of free radicals, which threatens the healthy appearance of skin and, even more worrying, damages the structural integrity of tissues and DNA, causing inflammation and carcinogenesis. This work demonstrates the feasibility of using natural agents, in particular tea catechins, in protecting lipidic membranes from oxidative stressinduced by UV radiation exposure. For that purpose, thin cast films prepared from vesicular suspensions of dimyristoylphosphatidylcholine (DMPC) and dimyristoylphosphatidylcholine  ()epigallocatechin3gallate (DMPC  EGCG) were deposited onto calcium fluoride supports and irradiated with 254 nm UV radiation. The molecular damage after irradiation with UV light was analysed by infrared (IR) together with 2D correlation spectroscopies. Results revealed that the DMPC phospholipid polar moiety is the most vulnerable and sensitive structural target of UV radiation. To check if the presence of the EGCG molecules is protecting the lipids, the principal components analysis (PCA) mathematical method was applied, allowing to conclude that EGCG slows down the cascade of the oxidantevents in the lipid, thus protecting the polar moiety of the lipid.
