Microscopy from Scientific Research

Asp-CQDs images using four fluorescence channels: bright field images, Hoechst (dye staining live cell nucleus), excitation at 480 nm, and excitation at 540 nm. A z-stack taken by a confocal microscope provides the 3D-projection showing the Hela cell with corresponding CQD nanomaterials. Scale bar: 20 μm.
