Right after 30 min of treatment, suggesting that microparticles, conjugated with folic acid, were accountable for the selectively for cancer cells (Figure S9). The co-localization with the blue (nuclei) and also the red (doxorubicin) fluorescence in tumor cells (Figure 8) recommended that the drug was released from the microgels and entered in to the nuclei, which can intercalate into the DNA causing cell death. ten of 17 On the other hand, microgels fluorescence signal was constantly localized in the cytoplasm (Figures S7 and S8).Gels 2021, 7, x FOR PEER REVIEW11 ofFigure 8.

Quantitative Uptake Study Differential microgel particles cellular uptake among standard and tumor cells was additionally 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 substantial differences in p(NIPAM)-co-5 AA-co-FA-co-Dox internalization be-Figure 9.
