Abstract
A method for determining ciprofloxacin in a meat product based on an enzyme-linked upconversion fluorescence and potassium titanium oxalate system is provided. An enzyme-linked upconversion nanoparticle solution is mixed with an aptamer-bound magnetized polydopamine solution to obtain a fluorescence-ultraviolet dual-signal detection system. A fluorescence standard curve and a colorimetric standard curve for the ciprofloxacin content determination are created through the fluorescence-ultraviolet dual-signal detection system in combination with potassium titanium oxalate and hydrogen peroxide. A fluorescence intensity signal characteristic value and an ultraviolet absorbance signal characteristic value of a meat sample solution are determined. A ciprofloxacin content in the meat sample is calculated according to the fluorescence standard curve and the colorimetric standard curve.
