中文摘要：

以光子晶体和分子印迹技术相结合,制备一种灵敏度高、特异性强、响应速度快的分子印迹光子晶体水凝胶膜（MIH）。该MIH以双酚A（BPA）为模板分子,以甲基丙烯酸（MAA）为功能单体、乙二醇二甲基丙烯酸酯（EGDMA）为交联剂,在紫外光下进行聚合。用扫描电镜（SEM）考察MIH表面特征,紫外-可见分光光度计来探究MIH对模板分子的响应特性。结果表明：MIH形成了有序的三维网状相互贯通的孔洞结构;同时MIH具有灵敏度高、选择性好、响应速度快等特点,当BPA磷酸盐缓冲液浓度从10-15mol/L增大到10-6mol/L时,MIH的布拉格衍射峰从597 nm移动到569 nm处;而在不同浓度BPA类似物（四溴双酚A）的磷酸盐缓冲液中基本上没有移动,非分子印迹光子晶体水凝胶膜（NIH）浸在不同浓度BPA磷酸盐缓冲液中,其布拉格衍射峰也基本上没有移动。

英文摘要：

A novel molecularly imprinted photonic hydrogel（MIH） for the high sensitive and rapid detection of bisphenol A（BPA） was constructed with the incorporation of photonic crystal and molecular imprinting technique.The MIH was prepared by UV lights with BPA as the template molecular,MAA as functional monomer,EGDMA as cross linker.The surface characterization and response performance of MIH was investigated by scanning electron microscope（SEM） and uv-vis spectrophotometer.The results showed that MIH possessed a highly ordered three-dimensional interconnected macroporous structure.The Bragg diffraction peak migrated from 597 nm to 569 nm when the concentration of BPA was augmented from 10-15 to 10-6 mol/L,however there was little peak shifts for tetrabromobisphenol A.The nonimprinted photonic hydrogel（NIH） was no response to BPA,demonstrating that MIH was rapid responsive,high selective and sensitive to BPA.
