Mica is the substrate of choice for microscopic visualization of a wide variety of intricate nanostructures. Unfortunately, the lack of a facile strategy for its modification has prevented the on-mica assembly of nanostructures. Herein, we disclose a convenient catechol-based linker that enables various surface-bound metal-free click reactions, and an easy modification of mica with DNA nanostructures and a horseradish peroxidase mimicking hemin/G-quadruplex DNAzyme.
云母是各种复杂纳米结构微观可视化的首选基质。然而，由于缺乏简便的修饰策略，阻止了纳米结构在云母上的组装。在此，我们揭示了一种方便的基于儿茶酚的连接物，它能够实现各种表面结合的无金属点击反应，并能够轻松地用 DNA 纳米结构和模拟辣根过氧化物酶的血红素/G-四链体 DNA 酶对云母进行修饰。
