Development of plasmonic biosensor with tooth-shaped fiber and hybrid AuNPs-cubic silver oxide interface for ultrasensitive detection of gentamicin in real food samples.

Gentamicin is an important pollutant in milk that causes harm to the human body. In this study, a plasmonic biosensor with a tapered multi-mode fiber (MMF) and four-core fiber (FCF) and multi-mode fiber (MMF) structure was developed. Localized surfac…
