Fluorescent enzyme-linked immunoassay strategy based on enzyme-triggered in-situ synthesis of fluorescent copper nanoclusters
TL;DR: A simple turn-on fluorescent ELISA platform using alkaline phosphatase (ALP) as the labeling enzyme and copper nanoclusters (CuNCs) as fluorescent indicator provides a cost-effective approach for sensitive detection of target proteins.

Histone-DNA interaction: an effective approach to improve the fluorescence intensity and stability of DNA-templated Cu nanoclusters.
TL;DR: The histone-DNA interaction is found to greatly improve the fluorescence intensity and stability of DNA-templated Cu nanoclusters (CuNCs), which would be highly beneficial for the application of CuNCs in biosensing/imaging.

β-Cyclodextrin-modified silver nanoparticles as colorimetric probes for the direct visual enantioselective recognition of aromatic α-amino acids
TL;DR: In this paper, a chiral recognition of aromatic α-amino acids was performed using the distance-dependent optical properties of AgNPs and the difference in inclusion binding strength between the aromatic amino acid enantiomers and the β-CD host.

Label-free fluorescent assay of T4 polynucleotide kinase phosphatase activity based on G-quadruplexe-thioflavin T complex.
TL;DR: This work proposed a novel label-free sensing strategy for T4 PNKP activity based on G-quadruplexe-thioflavin T fluorescent indicator that is easy and convenient to operate in homogeneous solution, and the whole assay process can be completed in a single tube.

Determination of the activity of T4 polynucleotide kinase phosphatase by exploiting the sequence-dependent fluorescence of DNA-templated copper nanoclusters
TL;DR: In this paper, a fluorometric method is described for the determination of the activity of the enzyme T4 polynucleotide kinase phosphatase (T4 PNKP), where a short 3′-terminus phosphorylated DNA strand is hybridized with a long DNA strand to produce a partially double-stranded DNA (dsDNA) substrate.
