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 …

Conspectus Metal ions can be beneficial or toxic depending on their identity, oxidation state,
and concentration. Therefore, the ability to detect and quantify different types of metal ions …

Exposure to even very low levels of lead, cadmium, and mercury ions is known to cause
neurological, reproductive, cardiovascular, and developmental disorders, which are more …

Metal ion sensors are an important yet challenging field in analytical chemistry. Despite
much effort, only a limited number of metal ion sensors are available for practical use …

Heavy metal lead accumulation in the environment pollutes the ecology systems and further
threatens the human health. It is necessary to develop a sensitive method to detect it. Here …

This review summarizes research on the metal-binding properties of catalytic DNAzymes,
towards the goal of understanding the structural properties leading to metal ion specificity …

Heavy metal contaminants such as lead ions (Pb2+), mercury ions (Hg2+) and silver ions
(Ag+) can cause significant harm to humans and generate enduring bioaccumulation in …

We introduce a novel solid-phase colorimetric sensor facilely fabricated by loading
unmodified gold nanoparticles into poly (oligo (ethylene glycol) methacrylate)(POEGMA) …

In the past few decades, biosensors have been gradually developed for the rapid detection
and monitoring of human diseases. Recently, functional nucleic-acid (FNA) biosensors have …
