Amperometric Biosensor Based on Zirconium Oxide/Polyethylene Glycol/Tyrosinase Composite Film for the Detection of Phenolic Compounds.

本研究开发了一种基于氧化锆/聚乙二醇/酪氨酸酶复合膜的安培型酚类生物传感器。首先将CTAB（hexacetyltrimethylammonium bromide）滴涂于屏印碳电极（SPCE）表面，使其带正电荷；随后将氧化锆纳米颗粒（ZrO2）与聚乙二醇（PEG）混合后滴涂于SPCE/CTAB上，通过静电相互作用形成复合膜；最后将酪氨...
