摘要: A simple and low-cost pyrolytic carbonization method has been performed for the easy synthesis of carbon quantum dots from soya-nuggets under an insufficient amount oxygen. Furthermore, hydrothermal functionalization carbonized black material after Soxhlet purification with nitric acid leads to formation its sized water soluble version. The hydrothermally functionalized, (wsCQDs) are highly fluorescent self-passivated, having a yield value ∼3%, small range size distribution. High photostability high solubility makes these potential candidates imaging purposes, we used labeling Escherichia coli cells.
