Colorimetric chemodosimeter based on diazonium-gold-nanoparticle complexes for sulfite ion detection in solution
A fast and simple colorimetric detection system for sulfite, based on diazonium–gold-nanoparticle(AuNP) complexation, has high selectivity and sensitivity in aqueous media. The positively charged diazonium has affinity for ...
Flexible colorimetric detection of mercuric ion by simply mixing nanoparticles and oligopeptides
A colorimetric detection system for Hg2+ in aqueous media is developed with high selectivity and sensitivity based on the mixing of gold nanoparticles and oligopeptides. Oligopeptides with cysteine (Cys) at both ends ...
Enhanced electrical conductivity of individual conducting polymer nanobelts
Afacile strategy for preparing 1D conducting polymer nanobelts with the width of the belts down to less than 50 nm is presented. Strong enhancement in the conductivity of individual polypyrrole (PPy) nanobelts is observed, ...
Colorimetric detection of mercury ions based on plasmonic nanoparticles
The development of rapid, specific, cost-effective, and robust tools in monitoring Hg2+ levels in both environmental and biological samples is of utmost importance due to the severe mercury toxicity to humans. A number of ...
