Metal ions are essential to many chemical, biological, and environmental processes. In the
past two decades, many DNA-based metal sensors have emerged. While the main …

Nucleic acids have been among the first targets for antitumor drugs and antibiotics. With the
unveiling of new biological roles in regulation of gene expression, specific DNA and RNA …

The double-helix structure of DNA, in which complementary strands reversibly hybridize to
each other, not only explains how genetic information is stored and replicated, but also has …

An electrochemical sensor was developed for attomolar Hg2+ detection. Three single-
stranded DNA probes were rationally designed for selective and sensitive detection of the …

As one of the serious threats to food safety and public health, heavy metal contamination in
food and agriculture-related matrices has aroused serious concern for the public and needs …

DNA serves as a versatile template for few-atom silver clusters and their organized self-
assembly. These clusters possess unique structural and photophysical properties that are …

Metal-mediated artificial DNA base pairs, consisting of two ligand-type nucleosides and a
bridging metal ion, are promising building units for constructing DNA-based …

Metal-mediated base pairs represent a topical area of research at the border of bioinorganic
chemistry, supramolecular coordination chemistry and DNA nanotechnology. In a metal …

Recently, metal-mediated base-pairs (metallo-base-pairs) have been studied extensively
with the aim of exploring novel base-pairs; their structures, physicochemical properties, and …

Cadmium (Cd) is one of the most toxic heavy metals. Exposure to Cd can impair the
functions of the kidney, respiratory system, reproductive system and skeletal system. Cd2+ …
