Figure 9From: Long-term exposure of CdTe quantum dots on PC12 cellular activity and the determination of optimum non-toxic concentrations for biological useConfocal images. Fluorescent confocal images to illustrate the morphology of the actin stained PC12 cells with no QDs (A) as a control and PC12 cells exposed to the QDs (B) [conc. 10-9 M] following 72 hours of co-incubation.
