Heavy metal ions are non-biodegradable and contaminate most of the natural resources
occurring in the environment including water. Some of the heavy metals including Lead (Pb) …

Anodic Stripping Voltammetry (ASV) has the capability to detect heavy metals at sub ppb-
level with portable and cheap instrumentation making it ideal for in the field (at the source) …

Color is everything: Hg 2+ in aqueous media is detected by the formation of thymidine-Hg 2+-
thymidine coordination complexes, which raises the melting temperature of the DNA …

Bismuth-coated carbon electrodes display an attractive stripping voltammetric performance
which compares favorably with that of common mercury-film electrodes. These bismuth-film …

Abstract Mercuric (Hg 2+) ions released from human activities, natural phenomena, and
industrial sources are regarded as the global pollutant of world's water. Hg 2+ ions …

A simple hydrothermal method was applied to prepare carbon nanodots (C dots) from o-
phenylenediamine (OPD). The C dots exhibit photoluminescence at 567 nm when excited at …

Semiconductor quantum dots (QDs) attract extensive research interest as optical labels for
sensing events. The unique photophysical properties of QDs, such as high fluorescence …

Mercury ions act as severe environmental pollutants and they have serious medical
effects.[1] Specifically, microbial biomethylation of mercuric ions (Hg2+) yields methyl …

Inorganic arsenic, a term which encompasses both As (III) and As (V) species, constitutes
the highest toxicological risk associated with arsenic in water in contrast to the organic …

We report a highly sensitive electrochemical sensor for the detection of Hg2+ ions in
aqueous solution by using a thymine (T)-rich, mercury-specific oligonucleotide (MSO) probe …
