[Applicability of bisphenol A detection by a planar waveguide fluorescent biosensor].

As a kind of environmental endocrine disruptors, bisphenol A received a wide attention around the world. The planar waveguide fluorescent biosensor can rapidly and sensitively detect traceable bisphenol A in water samples. Under the optimized test conditions, the typical calibration curve for BPA determination by the biosensor showed a detection limit of (0.
