Hi All,
I work with nanomaterials. Especially with Carbon Dots, with fluorescent properties (Max emission at 650 nm and Max excitation at 400 nm, sizes around 2nm). When we use Confocal Microscope for cell internalization, we get no fluorescence. However, it is possible to detect the shift very clearly in Flow Cytometry. Still, I think I have no choice but the Confocal Microscope to track Carbon Dots inside the cell. (It is not easy to show that these materials are inside the cell in TEM as well). What could be the reason for this situation? does anyone have a similar problem? I need your help. Why can not we detect these nanomaterials by Confocal but we can detect them by Flow Cytometer?
