Bright-blue-emission nitrogen and phosphorus-doped carbon quantum dots as a promising nanoprobe for detection of Cr(vi) and ascorbic acid in pure aqueous solution and in living cells

Abstract

Efficient synthesis of N,P-CQDs via a one-step hydrothermal method with a high quantum yield for potential applications in turn-off and turn-on detections of Cr(vi) and AA in vitro in living cells.
