Uptake of fluorescence-labeled PEG-fMLF nanocarriers derived from commercial PEGs or novel PB-PEGs in differentiated U937 cells after 4 h of incubation at 37°C. The means ± SD for three independent experiments are shown for each value. (* Statistically significant difference between the control PEG5K and the PEG-fMLF nanocarriers, p < 0.01) [101].
