Microwave-assisted synthesis of nitrogen-doped carbon dots using prickly pear as the carbon source and its application as a highly selective sensor for Cr(vi) and as a patterning agent

Abstract

Nitrogen-doped fluorescent carbon dots, prepared from prickly pear and m-xylylenediamine using microwave, selectively detect Cr(vi) in water. Sensing strips prepared from the CDs are successfully used in the field and also used as patterning agent.
