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

Abstract

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