Plasmonic Sensor Based on Interaction between Silver Nanoparticles and Ni2+ or Co2+ in Water

Silver nanoparticles capped with 3-mercapto-1propanesulfonic acid sodium salt (AgNPs-3MPS), able to interact with Ni2+ or Co2+, have been prepared to detect these heavy metal ions in water. This system works as an optical sensor and it is based on the change of the intensity and shape of optical abs...
