Raman imaging of cellular uptake and studies of silver nanoparticles effect in BJ human fibroblasts cell lines.

Silver nanoparticles (AgNPs) have been widely studied for their beneficial antimicrobial effect and have been considered by some to be a safe ingredient, as penetration of metal nanoparticles through the skin in vivo has not been proven. However, AgNPs are becoming a commonly applied nanomaterial for surface modifications of medical products which come into contact with damaged skin. In our experiments, we tested two commercially available AgNPs samples manufactured by electrolysis.
