Abstract
, and the most probable mechanism concluded from ultraviolet-visible spectroscopy, electrospray ionization-mass spectrometry, and fluorescence spectrophotometry is a mixed static and dynamic quenching. Furthermore, the cytotoxicity experiment results show that CDs have low toxicity and can be used for intracellular imaging.
