Abstract

Carbon dots are synthesized via nitric acid reflux with coal. It is found that neomycin has fluorescence quenching effect on carbon dots. A fluorescence sensing system for fast detection of neomycin is constructed based on inner-filter effect

and detection limit is 1. 0 mg·L

-1

. The content of neomycin in real samples is detected by this fluorescence sensing system with recoveries of 98. 3 % ～ 101. 6 %.
