摘要

A novel fluorescence polarization (FP) nanosensor based on λ exonuclease cleavage reaction and FP enhancement effect of gold nanoparticles (AuNPs) has been developed for the detection of T4 polynucleotide kinase activity and inhibition. This FP sensor exhibits higher detection sensitivity over traditional fluorescence sensors by two orders of magnitude.
