Abstract

En 中文

• A dye-conjugated albumin sensor was designed, prepared and characterized • The Förster resonance energy transfer from analyte to dye was verified • This sensor enables long-lived ratiometric detection of ochratoxin A (OTA) • On-site determination of OTA in real alcoholic beverages is achieved
