Colorimetric Hg2+ detection with a label-free and fully DNA-structured sensor assembly incorporating G-quadruplex halves.
TL;DR: A sensitive and fully DNA-structured ion sensor was built by integrating polyT sequences for highly selective Hg2+ recognitions and two flanking G-quadruplex halves for allosteric signal transductions and may be further extended to other sensors through a rational structural fusion between re-engineered aptameric and enzymic DNA sequences.

DNA-assisted electroless deposition of highly dispersed palladium nanoparticles on glassy carbon surface: Preparation and electrocatalytic properties
TL;DR: In this article, a simple and cost-effective strategy to prepare Pd nanoparticle decorated glassy carbon electrodes is reported, where Mechanically shortened fish sperm DNA molecules were used as effective nucleation templates for the deposition of highly dispersed PD nanoparticles on glassy Carbon electrodes.

Surface-initiated DNA self-assembly as an enzyme-free and nanoparticle-free strategy towards signal amplification of an electrochemical DNA sensor
TL;DR: The preliminary results have shown that a decrease (as compared to an amplification-free system) in detection limit by a factor greater than 300 can be easily achieved by cyclic voltammetry under still not optimized conditions, with an ability of differentiating a single base mutation.

Rational design of an optical adenosine sensor by conjugating a DNA aptamer with split DNAzyme halves.
TL;DR: Split halves of a hemin-binding DNAzyme have been assembled with an anti-adenosine aptamer to build a homogeneous allosteric sensor for adenosine with high selectivity and sensitivity.
