“…µg/mL), and mouse germline stem cells (10 µg/mL) (Braydich-Stollen et al, 2005;Gopinath et al, 2008;Mahmood et al, 2010). An in vitro study by Sur et al (2010) indicated that lactose-modified AgNPs enter A549 cancer cells at a higher rate compared to their entrance into L929 fibroblasts. Using an MTT assay, compared the effective concentration (EC50) values of AgNPs of different sizes (~5 nm, ~20 nm, and ~50 nm) and surface areas on different cell types (A549, HepG2, MCF-7, and SGC-7901 cells).…”
