“Switch-Off-On” Detection of Fe 3+ and F − Ions Based on Fluorescence Silicon Nanoparticles and Their Application to Food Samples
An approach to the detection of F − ions in food samples was developed based on a “switch-off-on” fluorescence probe of silicon nanoparticles (SiNPs). The fluorescence of the synthetic SiNPs was gradually quenched in the presence of Fe 3+ ion and slightly recovered with the addition of F − ion owing...
