Synthesis of CdTe/Fe₃O₄ for Quantitative Detection of BSA

Abstract:

A new kind of functionalized CdTe/Fe₃O₄ was synthesized for the quantitative and selective determination of bovine serum albumin (BSA). The effects of pH value, reaction time, temperature and dosage of CdTe/ Fe₃O₄ on the detection of BSA were investigated. Under optimal conditions, the straight line equation: F/F0=1.40412+0.07216 C (μmol/L) was found between the relative fluorescence intensity and the concentration of BSA in the range of 0.69-5.52 μmol/L, and the limit of detection was 0.18 μmol/L.
