纳米酶可以通过模拟天然酶的反应活性中心合成,其能够克服天然酶对环境敏感、价格昂贵、不易储存等缺点。自2007年发现Fe3O4纳米材料具有类过氧化物酶(POD-like)活性以来,越来越多的工作者致力于纳米酶的开发。天然酶中存在柔性的蛋白质支架,其与底物的结合可以引起结构变形,并将底物捕获到活性位点实现催化。纳米酶是由结构非常牢固和稳定的纳米材料制成的,因此催化底物的结构灵活性较差。所以,设计和调控纳米酶的结构,提高其与底物的亲和力,缩短底物与界面活性中心的距离是非常重要的命题。

纳米酶

纳米酶
       典型的纳米尺度因素,如尺寸、形态和表面结构特性对纳米酶的活性有显著影响。通过调控策略,纳米酶通常具有与天然酶相似的活性中心或电子传递结构,从而赋予纳米酶高效的活性。而固体表面Lewis酸位点有一个未被占据的轨道,Lewis碱可以提供一对孤电子,当分子被Lewis酸/碱位点捕获时,分子的成键轨道和反键轨道会相互作用。这个过程可以诱导电子从Lewis酸的空位轨道和Lewis碱的非键轨道转移,从而产生活化效应。因此,在模拟酶反应中需要探究纳米酶表面Lewis酸/碱活性中心的协同催化作用。Co3O4纳米材料作为一种典型的具有POD-like催化活性的纳米酶受到了广泛关注。由于Co3O4纳米材料中既有作为Lewis酸的金属阳离子,也有作为Lewis碱的氧阴离子,其表面Lewis酸/碱活性中心的协同催化作用机理有待深入研究。
        开发具有POD-like活性的纳米酶对于环境监测具有重要意义。对苯二酚(HQ)作为一种高剂量的环境污染物,具有毒性高、生物相容性差的特点,对生态环境和人体产生危害。根据废水综合排放标准,HQ在中国的最大排放浓度为0.3 mg•L-1。HQ的检测方法包括高效液相色谱法、电化学法等等。在不使用复杂仪器的情况下,需要研究简单、高效的非大型仪器检测方法。纳米酶的比色法具有灵敏度高、操作简单、价格低廉等特点,广泛应用于生物、环境和医学检测领域。检测信号可以通过比色传感器转换为颜色信号变化。比色检测信号的高灵敏度对于定量分析非常重要,发展比色检测的研究过程需要了解纳米酶与POD-like活性的构效关系机制。因此,探究表面         具有Lewis酸/碱活性中心的Co3O4类酶活性对高效的比色分析检测具有重要的意义。
山东大学化学与化工学院占金华教授团队采用NaBH4还原法制备了具有丰富表面固体Lewis酸/碱位的超薄多孔Co3O4纳米片。对多孔Co3O4纳米片的类酶性能进行了评价和优化。探讨了超薄多孔Co3O4纳米片与TMB或H2O2底物分子的界面活化机理。为HQ环境检测提供了一种比色传感策略,并制备了琼脂糖基水凝胶膜用于大规模实际分析。
