Heavy metals accumulating in the human body produce physiological toxicity by interfering
with the transport of human proteins and enzymes. Heavy metals detection is significant for …

Heavy metal and metalloid poisoning in the environment and food has piqued the public's
interest since it poses significant hazards to the ecological system and human health. In …

The development of reliable and ultrasensitive detection marker for mercury ions (Hg 2+) in
drinking water is of great interest for toxicology assessment, environmental protection and …

Gold based structures such as nanoparticles (NPs) and nanowires (NWs) have widely been
used as building blocks for sensing devices in chemistry and biochemistry fields because of …

Selected from random pools of DNA or RNA molecules through systematic evolution of
ligands by exponential enrichment (SELEX), aptamers can bind to target molecules with …

Heavy metal ions, such as Hg2+ and Ag+, pose severe risks in human health and the
environment. For sensitive detection and selective removal of Hg2+ and Ag+ ions, here, we …

Gold nanoparticles (AuNPs)/reduced graphene oxide (rGO) heterojunctions were
synthesized directly on SiO2/Si substrates via a seed-assisted growth process. The in situ …

We report the rapid and highly sensitive trace analysis of mercury (II) ions in water using a
surface-enhanced Raman scattering (SERS)-based microdroplet sensor. Aptamer-modified …

Mercury being one of the most toxic heavy metals has long been a focus of concern due to
its gravest threats to human health and environment. Although multiple methods have been …
