Kinetics and mechanism of G-quadruplex formation and conformational switch in a G-quadruplex of PS2.M induced by Pb2+
TL;DR: Using circular dichroism and ultraviolet-visible spectroscopy, the spectral characteristics and the overall conformation of a G-quadruplex of PS2.M with an oligonucleotide sequence are determined andKinetic studies suggest that the Pb2+-induced folding of PS.M to G- quadruplex probably proceeds through a three-step pathway involving two intermediates.

TL;DR: A detachable DNA circuit is developed by embedding a pH-controlled intermolecular triplex between the toehold and branch migration domain of the traditional "linear substrate" to provide a facile approach for dynamic regulation of complex molecular systems and reprogrammable nanoparticle assembly structures.

Small organic molecules detection based on aptamer-modified gold nanoparticles-enhanced quartz crystal microbalance with dissipation biosensor.
TL;DR: An aptamer-based gold nanoparticles (AuNPs)-enhanced sensing strategy for detection of small molecules was developed and the resulting aptasensor exhibited several excellent characteristics such as high sensitivity, selectivity, good stability, and reproducibility.

Study of the binding way between saxitoxin and its aptamer and a fluorescent aptasensor for detection of saxitoxin.
TL;DR: The proposed method provides not only an alternative for STX detection but also a strategy for simple aptasensor design using aptamers that do not switch conformation upon targets binding.
