Microscopic examination of uptake of fluorescently labelled PLGA-NH2 nanoparticles by RAW264.7 cells after 24 h. Uptake of a small (300 nm), b intermediate (600 nm), and c large (900 nm) nanoparticles, following inhibition of phagocytosis. d Quantification plots depicting the uptake of nanoparticles of different sizes. Data are presented as mean ± SEM (n = 3). NP-F S/M/L: fluorescently labelled nanoparticles small/intermediate/large; PLGA: poly(lactic-co-glycolic acid); SEM: standard error of mean
