Figure 4From: Quantum dots incorporated magnetic nanoparticles for imaging colon carcinoma cellsStability of prepared FMNPs at room temperature (A), fluorescence images of FMNPs at different stages (B), and cell viability in the presence of FMNPs (C). The cytotoxicity of the FMNPs was measured using Vero cells by the trypan blue exclusion test.Back to article page
