title: Sensitive and selective detection of silver(I) ion in aqueous solution using carbon nanoparticles as a cheap, effective fluorescent sensing platform.
abstract: In this Letter, we demonstrate the first use of carbon nanoparticles (CNPs) obtained from carbon soot by lighting a candle as a cheap, effective fluorescent sensing platform for Ag(+) detection with a detection limit as low as 500 pM and high selectivity. We further demonstrate its practical application to detect Ag(+) in a real sample.
