原始语种摘要: Abstract(#br)A rapid and sensitive detection method for phthalate esters (PAEs) was developed by using an optical fiber immunosensor based on indirect competitive immunoassay. This sensor was constructed by covalent binding of coating antigen on the surface of optical fiber, and the inhibition signal of PAEs to immune reaction between coating antigen and fluorescent-labeled antibody was detected by avalanche photodiode. The response signal showed a negative correlation with the logarithm of PAEs concentration in the range of 0.01–100μg/L, and the limits of detection (LODs) of eight PAEs ranged from 19 to 51ng/L. The fluorescent-labeled antibody displayed broad cross-reactivity in the range of 16.63%–71.94% for the other seven PAEs (100% for dimethyl...
