The reliable, readily accessible and label-free measurement of aptamer binding remains a challenge in the field. Recent reports have shown large changes in the intrinsic fluorescence of DNA upon the formation of G-quadruplex and i-motif structures. I

With more and more new aptamers being reported, a general, cost-effective yet reliable aptamer binding assay is still needed. Herein, we studied cationic conjugated polymer (CCP)-based binding assays taking advantage of the conformational change of a

The intrinsic fluorescence of a few G-quadruplex forming DNAs was quenched by Pb2+but enhanced up to 9-fold by K+. Such fluorescence change allowed label-free monitoring of metal binding kinetics, displacement and selectivity.

Target molecule-induced desorption of aptamer probes from nanomaterials has been a very popular sensing method, taking advantage of the fluorescence quenching or catalytic activity of nanomaterials for signal generation. While it is generally conceiv

Fluorescence polarization (FP) is attractive for measuring binding interactions and has been recently used to study DNA adsorption on nanomaterials. Since most nanomaterials are strong fluorescence quenchers, correlations among adsorption efficiency,

Nucleobase–metal coordination polymers (CPs) have been the target of much recent research owing their interesting properties and ease of preparation. Natural nucleobases are nonfluorescent, and 2-aminopurine (2AP) is a strongly fluorescent analog o

Shorter DNA probes provide better specificity for hybridization, but they may not form stable duplexes at room temperature. In this study, we used thiazole orange to follow DNA hybridization upon freezing and achieved stable 5-mer duplex DNA. Using m
