Nitrogen-doped graphene quantum dots coated with molecularly imprinted polymers as a fluorescent sensor for selective determination of warfarin

Abstract

The strong photoluminescence of NGQDs and the selectivity of MIPs were combined to construct a fluorescent sensor for rapid determination of warfarin.

Nanomaterial-Based Sensors for Coumarin Detection

“…Demonstrating specific selectivity and superior detection performance for warfarin, the fluorescence intensity of the NGQDs@MIPs sensor presented an excellent linear response with warfarin concentrations ranging from 0.63 to 10 μM with a LOD of 0.16 μM. 210 …”

“…Demonstrating specific selectivity and superior detection performance for warfarin, the fluorescence intensity of the NGQDs@MIPs sensor presented an excellent linear response with warfarin concentrations ranging from 0.63 to 10 μM with a LOD of 0.16 μM. 210 Zhao et al formed a molecularly imprinted electrochemical sensor for coumarin detection and applied AuNP-modified reduced graphene oxide (rGO) on a glassy carbon electrode (GCE). Modification of AuNP/rGO is carried out through the deposition of coumarin template molecules.…”
