| 英文摘要 | hydrophilic nanographene (ngp) prepared by ball milling of graphite was used as the support to construct a novel tyrosinase biosensor for determination of bisphenol a (bpa). the performances of the nanographene-based tyrosinase biosensor were systematically compared with those of multiwall carbon nanotubes (mwnts) modified tyrosinase biosensors. the results indicated that the nanographene-based tyrosinase biosensor provided significant advantages over mwnts-based tyrosinase biosensor in term of response, repeatability, background current and limit of detection (lod), which could be attributed to its larger specific surface area and unique hierarchical tyrosinase-ngp nanostructures. the nanographene-based tyrosinase biosensor displayed superior analytical performance over a linear range from 100 nmol l-1 to 2000 nmol l-1, with lod of 33 nmol l-1 and sensitivity of 3108.4 ma cm(-2) m-1. the biosensor was further used for detecting bpa (leaching from different vessels) in tap water, and the accuracy of the results was validated by high performance liquid chromatography (hplc). the nanographene-based tyrosinase biosensor proved to be a promising and reliable tool for rapid detection of bpa leached from polycarbonate plastic products and for on-site rapid analysis of emergency pollution affairs of bpa.
