Right after 30 min of therapy, suggesting that microparticles, conjugated with folic acid, had been accountable for the selectively for cancer cells (Figure S9). The co-localization on the blue (nuclei) and also the red (doxorubicin) fluorescence in tumor cells (Figure 8) suggested that the drug was released in the microgels and entered into the nuclei, which can intercalate into the DNA causing cell death. 10 of 17 However, microgels fluorescence signal was constantly localized within the cytoplasm (Figures S7 and S8).Gels 2021, 7, x FOR PEER REVIEW11 ofFigure eight.

Quantitative Uptake Study Differential microgel particles cellular uptake among regular and tumor cells was moreover investigated by the quantitative flow cytometric evaluation, following the red autofluorescence of conjugated doxorubicin (Figures 9 and S10). Initially (30 min), there had been no considerable differences in p(NIPAM)-co-5 AA-co-FA-co-Dox internalization be-Figure 9.
