Heavy metals are one of the most hazardous inorganic contaminants of both water and soil
environment composition. Normally, heavy metals are non-biodegradable in nature because …

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 …

In small quantities, certain heavy metals (eg, iron, copper, manganese, and zinc) are
nutritionally essential for a healthy life. However, heavy metals show a great trend to form …

Recently, aptamers have attracted the attention of many scientists, because they not only
have all of the advantages of antibodies, but also have unique merits, such as thermal …

Electrochemical biosensors combine the sensitivity of electroanalytical methods with the
inherent bioselectivity of the biological component. The biological component in the sensor …

Abstract Metal-organic frameworks (MOFs), composed of metal ions and organic connector,
are a new group of novel porous materials. In light of their advantageous features (eg, high …

Several pollutants are getting added to the water content in today's world, sometimes
intentionally and sometimes unintentionally. These pollutants, chemicals, and heavy metals …

Immunoassays are bioanalytical methods in which the quantitation of the analyte depends
on the reaction of an antigen (analyte) and an antibody. Immunoassays have been widely …

Whole cell microbial biosensors are offering an alternative means for rapid, on-site heavy
metal detection. Based in microorganisms, biosensing constructs are designed and …

A catalytic beacon sensor for Pb2+ has been developed based on the first DNAzyme
discovered in the field, and such a sensor has shown a much higher metal ion selectivity (40 …
