| Abstract: | The purpose of this study was to establish a simple, sensitive analytical method for kanamycin (KANA) in human urine. Enhancement
of the plasmon resonance light-scattering (PRLS) of gold nanoparticles (AuNPs) by KANA provided the basis for this analytical
method. At pH 6.7, KANA induced AuNPs aggregation with enhanced PRLS. The PRLS of the AuNPs–KANA system was further enhanced
by addition of urea. The linear range and detection limit for KANA were from 20–800 nmol L−1 and 2 nmol L−1, respectively. Potential interfering substances present in urine had a negligible effect on the determination, thus preliminary
sample separations were not necessary. Recovery of KANA from spiked human urine was 94–104%. This simple, sensitive method,
using urea to enhance the PRLS of the AuNPs–KANA system, may provide a new approach for determination of compounds rich in
OH groups. |
