Abstract

Abstract Fluorescence resonance energy transfer occurs between levofloxacin (LVFX) and gold nanoparticles (AuNPs), which leads to fluorescence quenching of levofloxacin. Due to the strong Au-S bond formed between thiourea dioxide and gold nanoparticles, levofloxacin is released from the surface of gold nanoparticles and fluorescence of the system is recovered. Based on this, a fluorescence spectrometry method for determination of thiourea dioxide was established. This method was used to determine the content of thiourea dioxide in pasta products with RSD less than 3.5% and recovery rate of 93.3~103.3%.
