Abstract Copper (Cu 2+) exists in nature and biological systems and therefore its detection
in soil, blood, urine, water, agriculture and food samples is of great significance. Attempts to …

The electron-rich five-membered aromatic aza-heterocyclic imidazole, which contains two
nitrogen atoms, is an important functional fragment widely present in a large number of …

Hydrogen sulfide (H2S) is not only a well-established toxic gas but also an important small
molecule bioregulator in all kingdoms of life. In contemporary biology, H2S is often classified …

An one-pot hydrothermal method was developed for synthesis of carbon quantum dots co-
doped with copper and nitrogen (Cu, N@ CQDs). The synthesized Cu, N@ CQDs has …

A novel oxene based unusual sensory receptor (HyMa) has been synthesized via.
Knoevenagel condensation triggered carbon-heteroatom (oxygen) intramolecular bond …

Pathogenic bacteria cause disease outbreaks and threaten human health, prompting the
research on advanced detection assays. Herein, we developed a selective molecular …

In this study, a novel “on–off–on” fluorescent probe was suggested for sensitive and
selective assay of glutathione (GSH). The as-fabricated nanoswitch employs a Cu2+–sulfur …

Heavy metals (HMs) are metallic substances. They enter biotic and abiotic systems through
natural and human activities. These HMs have an impact on the atmosphere, soil, and …

Water contamination caused by heavy metals represents an urgent global issue. Cu 2+, a
potential trace heavy metal pollutant, can accumulate in the human body through the food …

A highly responsive and selective coordinated molecularly imprinted polymer (MIP)-
dependent ratiometric electrochemical platform for ciprofloxacin (CIPX) detection was …
