A novel fluorescent nanoprobe that based on poly(thymine) single strand DNA-templated copper nanocluster for the detection of hydrogen peroxide

Fluorescent detection of emerging virus based on nanoparticles: From synthesis to application

“…The production of NIR-emitting DNA-stabilized silver nanoclusters (DNA-AgNCs), with an extraordinarily high fluorescence QY, was proposed by Neacsu et al [ 87 ]. Additionally, Chai et al synthesized poly-thymidine single-stranded protected fluorescent copper nanoclusters for label-free and cost-free detection of H 2 O 2 in serum samples [ 88 ].…”

Dual-emission copper nanoclusters–based ratiometric fluorescent probe for intracellular detection of hydroxyl and superoxide anion species

“…Besides, the advancements in the field of nanochemistry have enabled the synthesis of CuNCs with tailored size and functionality. Until date, few studies have reported CuNCs as a sensitive probe for the detection of ROS including hypochlorite (ClO − ) [37,38] and hydrogen peroxide (H 2 O 2 ) [39,40]. However, these CuNCs-based probes rely on the changes in single emission intensity which are prone to the environmental interferences and could affect the ROS detection sensitivity.…”

“…The ideal probe should have high sensitivity for selectively detecting the target analyte [37,40,42]. With due consideration, the fluorescence responses of PCuNCs-BCuNCs towards ROS were monitored in solution under physiological conditions.…”
