Existing at the interface of biology and electronics, living cells have been in use as
biorecognition elements (bioreceptors) in biosensors since the early 1970s. They are an …

Biofilms are assemblages of bacteria embedded within a matrix of extracellular polymeric
substances (EPS) attached to a substratum. The process of biofilm formation is a complex …

Mercury (Hg) and its inorganic and organic compounds significantly threaten the ecosystem
and human health. However, the natural and anthropogenic Hg environmental inputs …

Quorum sensing (QS) is a molecular signaling modality that mediates molecular-based cell–
cell communication. Prevalent in nature, QS networks provide bacteria with a method to …

Mercury pollutants such as mercuric chloride (HgCl 2), mercurous chloride (Hg 2 Cl 2) and
mercuric ammonium chloride (Hg (NH 2) Cl) are often found in cosmetics. Previous attempts …

Engineered microorganisms have proven to be a highly effective and robust tool to
specifically detect heavy metals in the environment. In this study, a highly specific pigment …

Environmental risks continue to grow due to heavy metal contamination caused by
anthropogenic activities. Accumulation of harmful quantities of lead poses a threat to aquatic …

The frequent exposure and accumulation of heavy metals in organisms cause serious health
issues affecting a range of organs such as the brain, liver, and reproductive organs in adults …

The toxicity of mercury (Hg) mainly depends on its form. Whole-cell biosensors respond
selectively to toxic Hg (II), efficiently transformed by environmental microbes into …

During the last few decades, whole-cell biosensors have attracted increasing attention for
their enormous potential in monitoring bioavailable heavy metal contaminations in the …
