Most heavy metal ions are known to be toxic and carcinogenic when present in high
amounts. Thus, rapid and reliable on-site detection of these ions is crucial. Voltammetry is a …

Heavy metal ions, one of the most important pollutants today, widely exist in the
environment, and can cause different degrees of damage to the ecological environment and …

A colorimetric-electrochemical dual-mode analytical method based on bismuth metal-
organic framework nanozyme was developed for label-free and trace/ultra-trace Cr 6+ …

Converting toxic Cr (VI) to benign Cr (III) would offer a solution to decontaminate drinking
water. Electrochemical methods are ideally suited to carry out this reduction without added …

The intensive research on the synthesis and characterization of gold (Au) nanostructures
has been extensively documented over the last decades. These investigations allow the …

Chromium contamination of drinking water has become a global problem due to its
extensive use in industry. The most commonly used methods for chromium detection in …

Monitoring heavy metals in wastewater streams is necessary to comply with standard
governmental water treatment and discharge policies. Electrochemical heavy metal …

It is of great significance to develop versatile and cost-effective point-of-care testing (POCT)
systems for simultaneous quantitation of multiple analytes on-site. This work reports on: 1) …

Abstract Novel C-BiOCl/Bi 2 S 3 composites are prepared by hydrothermal C doping in
BiOCl and in-situ growth of Bi 2 S 3 on C-BiOCl. Compared with BiOCl, C-BiOCl has a larger …

Nanozymes have been widely utilized in colorimetric sensors and developing nanomaterials
with multienzyme functions have more application prospects due to their cascaded catalytic …
