Fig. 6From: Dynamic Cellular Uptake of Mixed-Monolayer Protected NanoparticlesRate of change of fluorescence intensity versus incubation time for HeLa, 3T3, and DC2.4 cells at both 4 and 37°C. It is apparent that most of the variation in fluorescence intensity (and therefore NP internalization) is found in early times under a few hoursBack to article page
