Abstract:

A sensitive method based on the sodium dodecyl sulfate-stabilized silver nanoparticles (SDS-AgNPs) for detection of levofloxacin was reported. Levofloxacin could rapidly induce the aggregation of SDS-AgNPs, thereby resulting in a yellow-to-red color change. The color change could be monitored by naked eye and UV-Vis spectrophotometry. The presented method is convenient, simple, cost-effective and suitable for comprehensive laboratory teaching to develop students' innovation and scientific research ability.

Key words: Levofloxacin, Silver nanoparticles, Sodium dodecyl sulfate (SDS), Instrumental analysis experiment
