G The drug loading rate of synthetic liposomes was determined by inductively coupled plasma optical emission spectrometry (ICP-OES) at different particle sizes and (H) different charges [64]. Copyright 2019, MDPIA Schematic of the preparation of ATF-IONP-Gem. B Drug release condition and efficiency. IONPs, IONP-Gem, ATF-IONP-Gem, and human pancreatic cancer cells were incubated in 100 nm and 10 nm for 4 h, then Prussian blue staining was performed. C IONPs in cells were detected as blue-stained cells. D the OD value was quantitatively detected at 680 nm with a micro board reader. E The observed bright-field microscopic images of Prussian blue-stained cells under 40 × magnifications of. F the number of living cells per well in a 96-well tissue culture plate was determined by the MTT method [76].Back to article page
