Heavy metal ions are one of the main sources of water pollution. Most heavy metal ions are
carcinogens that pose a threat to both ecological balance and human health. With the …

The existence of arsenic in the environment poses severe global health threats. Considering
its toxicity, the sensing of arsenic is extremely important. Due to the complexity of …

Due to the great importance of inorganic arsenic detection for global environment and
human health, many methods and techniques have been developed in the past decades for …

Developing a new ultrasensitive interface to detect As (III) is highly desirable because of its
seriously toxic and low concentration in drinking water. Recently, Fe3O4 nanoparticles of …

Arsenic occurs in the natural environment in four oxidation states: As (V), As (III), As (0) and
As (− III). The behavior of arsenic species changes depending on the biotic or abiotic …

Heavy metals are one of the major factors which have been degrading our environment at a
tremendous rate which unfortunately exploits the natural resources. Major heavy metals …

Arsenic is extremely abundant in the Earth's crust and is one of the most common
environmental pollutants in nature. In the natural water environment and surface soil …

In this study, a sensitive aptasensor based on three-dimensional reduced graphene oxide-
modified gold nanoparticles (3D-rGO/AuNPs) was fabricated for the determination of …

Arsenic (As) is a type of highly toxic substance, which is widely distributed in environment
due to both natural and anthropogenic sources. For health concerns, the allowable arsenic …

The goethite (α-FeOOH) nanoparticles were wrapped on the reduced graphene oxide (rGO)
to synthesize the α-FeOOH/rGO nanocomposites. The nanocomposites (NCs) were initially …
