Heavy metal pollution has become a severe threat to human health and the environment for
many years. Their extensive release can severely damage the environment and promote the …

In the last decade, metallic nanoparticles of noble metal ions as gold and silver have
received much attention mainly due to their colorimetric properties. These metallic …

Using graphitic carbon nitride (gC 3 N 4) nanosheets, an effective and facile fluorescence
sensing approach for the label-free and selective determination of chromium (VI)(Cr (VI)) …

A highly sensitive and selective detection of hexavalent chromium (Cr (VI)) and ascorbic
acid (AA) was proposed using nitrogen-doped carbon dots (N-CDs). In the absence of AA …

Chromium is a harmful contaminant showing mutagenicity and carcinogenicity. Therefore,
detection of chromium requires the development of low-cost and high-sensitivity sensors …

Abstract The MXene quantum dots (MQDs) derived from two-dimensional MXene
nanosheets is a kind of rising-star nanomaterial recently, exhibiting important applications in …

The work presents the facile green synthesis of blue luminescent C-dots (CDs) using
papaya waste (Carica papaya) as a precursor. The as-synthesized CD S exhibit a quantum …

In this work, amino-functionalized mesoporous silica nanospheres (NH 2-mSiO 2) anchored
with carbon dots (CDs) have been designed to construct an outstanding fluorescent sensor …

In this work, the electronic and molecular structure, as well as the morphology, of innovative
nanostructured materials whose optical properties respond to the presence of heavy metals …

Colloidal inorganic nanoparticles have wide applications in the detection of analytes and in
biological assays. A large number of these assays rely on the ability of gold nanoparticles …
