“…Different carbon-based materials are used in solar cells, supercapacitors, light-emitting diodes, sensors, food safety, ion detection, pharmacology, and hydrophobic coatings [1][2][3][4][5][6][7][8][9][10][11]. Fluorescent carbon dots (CDs) represent a new class of carbon nano-size materials, which are of great interest as potential competitors to traditional semiconductor quantum dots.…”
