Abstract(summary):

Herein, we have prepared two kinds of carbon dots (CDs) on the basis of pea (p-CDs) and sesame (s-CDs) through a facile hydrothermal way. Basically, the two CDs described here exhibited obvious superiority mainly including satisfactory stability, non-toxicity and photobleaching resistance, and also the whole synthesis procedures for both p-CDs and s-CDs were environmental-friendly. Significantly, p-CDs showed specific binding with pathogenic fungus of Cryptococcus neoformans, and thereby revealing the potential of staining the fungus. Additionally, we employed Cryptococcus neoformans to infect mice, and utilized p-CDs to trace the positions of the fungus, proving the fluorescent-staining prospect of p-CDs.
