Supramolecular quantum dots as biodegradable nano-probes for upconversion-enabled bioimaging†
Abstract
We report the biodegradable supramolecular quantum dots (SQDs) of hydrogen-bonded graphitic carbon nitride (g-C3N4) with low cytotoxicity and desirable biocompatibility for promising upconversion-enabled fluorescent bio-probes. A remarkable biodegradation of up to 97% within 24 hours is presented.
