The oxides of transition, post-transition and rare-earth metals have a long history of robust and fast responsive recognition elements for electronic, optical, and gravimetric devices. A wide range of applications successfully utilized pristine or doped metal oxides and polymer-oxide hybrids as nanostructured recognition elements for the detection of biologically relevant molecules, harmful organic substances, and drugs as well as for the investigative process control applications. An overview of the selected recognition applications of molecularly imprinted sol-gel phases, metal oxides and hybrid nanomaterials composed of molecularly imprinted polymers (MIP) and metal oxides is presented herein. The formation and fabrication processes for imprinted sol-gel layers, metal oxides, MIP-coated oxide nanoparticles and other MIP/oxide nanohybrids are discussed along with their applications in monitoring bioorganic analytes and processes. The sensor characteristics such as dynamic detection range and limit of detection are compared as the performance criterion and the miniaturization and commercialization possibilities are critically discussed.
过渡金属、后过渡金属和稀土金属的氧化物作为电子、光学和重量分析设备中坚固且响应迅速的识别元件已有很长的历史。广泛的应用成功地将原始或掺杂的金属氧化物以及聚合物-氧化物杂化物用作纳米结构识别元件,用于检测生物相关分子、有害有机物质和药物,以及用于研究过程控制应用。本文概述了分子印迹溶胶-凝胶相、金属氧化物以及由分子印迹聚合物(MIP)和金属氧化物组成的杂化纳米材料的选定识别应用。讨论了印迹溶胶-凝胶层、金属氧化物、MIP包覆的氧化物纳米颗粒和其他MIP/氧化物纳米杂化物的形成和制备过程,以及它们在监测生物有机分析物和过程中的应用。将动态检测范围和检测限等传感器特性作为性能标准进行比较,并对小型化和商业化可能性进行了批判性讨论。
