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.
