doi: 10.3390/nano9030396

Figure Lengend Snippet: E-GNPs exhibit selective and superior anticancer activity. 5 × 10 3 noncancerous cells (HaCaT, MCF-10A, HPNE, and RWPE1) and cancerous cells (A375SM, MDA-MB-231, MIA PaCa, and PC3) were seeded in 96-well plates and treated with different concentrations of E-GNPs, epigallocatechin gallate (EGCG), C-GNPs, or citrate for 96 h, and cell viability was determined by WST-1 assay. Data represent the mean of triplicates ± SD.
