From: Anticancer and antimicrobial activity of biosynthesized Red Sea marine algal silver nanoparticles

The microscopical visualization (20x) of the human skin cell line (HFb-4) distinguished the variation in the cell viability according to their treatment with biosynthesized AgNPs capped by different marine algal extracts, (a) U. rigida, (b) C. myrica, (c) G. foliifera, (d) non-biogenic AgNPs and (e) untreated control cells.
