Fig. 8From: Gemcitabine-loaded PLGA-PEG immunonanoparticles for targeted chemotherapy of pancreatic cancerPercent viability measured by MTT assay on human pancreatic cells. An optical density value of unexposed cells, PLGA NPs, and Ab PLGA-PEG NPs was taken as 100 % viability (0 % cytotoxicity) for drug, drug-loaded PLGA, and drug-loaded Ab PLGA-PEG NPs, respectively. *p < 0.05, compared to plain drugBack to article page
