Most of the metal ions are carcinogens and lead to serious health concerns by producing
free radicals. Hence, fast and accurate detection of metal ions has become a critical issue …

A microbial biosensor is an analytical device with a biologically integrated transducer that
generates a measurable signal indicating the analyte concentration. This method is ideally …

This review analyzes the advantages and disadvantages of using eukaryotic
microorganisms to design whole-cell biosensors (WCBs) for monitoring environmental …

A phenomenon of changes in photoluminescence of porous silicon at variations in medium
pH is proposed to be used as a basis for the biosensor system development. The method of …

The book provides an introduction of surface plasmons and presents its applications in the
sensing of various chemical and biological analyses using optical fiber technology. The field …

Contamination of water by heavy metals represents a potential risk for both aquatic and
terrestrial organisms, including humans. Heavy metals in water resources can come from …

Reporter-gene-based microbial biosensors have high potential for detecting small
molecules, including heavy metal ions (HMIs), in a sensitive and selective manner by …

A graphene nanodots-encaged porous gold electrode via ion beam sputtering deposition
(IBSD) for electrochemical sensing is presented. The electrodes were fabricated using Au …

The toxicity of quantum dots (QDs) has been commonly attributed to the release of metal
ions from the core as well as to the production of reactive oxygen species. However, the …

Zinc, lead and cadmium are metallic trace elements (MTEs) that are widespread in the
environment and tend to accumulate in soils because of their low mobility and non …
