The quick and high-accuracy location of heavy metals is one of the principal prerequisites
for reducing the environmental pollution. Therefore, the rapid and precise detection of heavy …

Chlorpyrifos (CPF), an organophosphate insecticide, is widely identified in fruit juices. In this
study, a novel molecularly imprinted polymers-surface-enhanced Raman spectroscopy …

The present work offers a new exploration for the selective sensing of metal ions (Ag+ and
Mn 2+) via fluorescence quenching of Ti 3 C 2 MXene nanosheets (NSs). Monolayer MXene …

A colorimetric assay is proposed for the selective detection of Cr (III) and Cr (VI) via the
aggregation-induced color change of gallic acid capped gold nanoparticles (GA-AuNPs) …

Hexavalent chromium ion (Cr6+) is one of the most toxic substances for plants, for animals,
and is a confirmed human respiratory carcinogen. However, so far, there are few …

A smartphone-based microfluidic platform was developed for point-of-care (POC) detection
using surface plasmon resonance (SPR) of gold nanoparticles (GNPs). The simultaneous …

We report a facile, selective, and sensitive colorimetric assay for Mn 2+ ions based on the
anti-aggregation of unmodified silver nanoparticles (AgNPs). In the absence of Mn 2+ ions …

Functionalized graphene oxide quantum dots (GOQDs)–poly (vinyl alcohol)(PVA) hybrid
hydrogels were prepared using a simple, facile and cost-effective strategy. GOQDs bearing …

Owing to the detrimental effect on human health, the contamination of drinking water and
water sources by metal and heavy metal ions has received significant attention from the …

In this work, we have described the use of sulfoanthranilic acid dithiocarbamate
functionalized silver nanoparticles as a probe for simple, rapid and simultaneous …
