Figure 7From: Folic acid conjugated cross-linked acrylic polymer (FA-CLAP) hydrogel for site specific delivery of hydrophobic drugs to cancer cells Cytotoxic effect of folic acid-conjugated PAA nanocurcumin. HeLa cells were treated with folic acid-conjugated PAA (FA-CLAP) nanocurcumin or curcumin in DMSO. Optical densities were measured and relative cell viability was plotted.Back to article page
