Preparation of strong green fluorescence carbon quantum dots for cancer cell imaging

Abstract

Carbon quantum dots (CQDs) were prepared throught hydrothermal synthesis method. The TEM and FT-IR spectra showed the successful synthesis of CQDs and the well water solubility of CQDs. After CQDs were co-cultured with human breast cancer cells (MCF-7 cells), the cells were stained and emitted stronge green fluorescence, indicated that CQDs had a good application prospect in cancer cell imaging.
