Negatively charged ions are an integral part of our ecosystem, where at certain
concentrations (fixed by the Environmental Protection Agency (EPA) and World Health …

Hydrogen sulfide (H 2 S) signaling has been implicated in physiological processes in
practically all organ systems studied to date. At times the excitement of this new field has …

Colloidal semiconductor nanocrystals or quantum dots (QDs) have been facilitating the
development of sensitive fluorescence sensors over the past decade, due to their unique …

The article describes a simple method for the rapid photometric and visual detection of
sulfide in water samples. Silver nanoparticles were capped with chitosan (chit-AgNPs) and …

Because of the fact that carbon dots (CDs) generally do not show satisfied fluorescence
activities, developing indirect approaches to use these nanomaterials as fluorescence …

Nanotechnology has emerged as one of the most potential areas for pharmaceutical
analysis. The need for nanomaterials in pharmaceutical analysis is comprehended in terms …

A novel ratiometric fluorescence strategy for sulfide ions (S 2-) analysis has been developed
using metal–organic framework (MOF)-based nanozyme. NH 2-Cu-MOF displays blue …

Carbon quantum dots (CQDs)-doped CdS (C/CdS) microspheres were successfully
synthesized by tuning the concentration of CQDs in the solutions with glutathione as a …

Nitrogen-and sulfur-codoped carbon dots (N, S-CDs) with a fluorescence quantum yield of
16.1% and good photoluminescent properties were synthesized by a simple hydrothermal …

The present study illustrates the synthesis of silver nanoparticles capped with carbon dots
(AgNPs-CDs) and their application towards the sensitive and selective sensing of sulfide …
