利用扫描探针显微镜（SPMs）制备了由两种不同类型的有机硅烷单层组成的共面纳米结构，并作为各种材料的区域选择性固定模板。在衬底上均匀制备的第一层有机硅烷单分子层，通过电化学作用在单分子层和SPM探针交界处吸附的水进行局部降解。探针扫描的区域化学吸收了第二有机硅烷分子，从而形成了一个自组装的单层（SAM），局限于spm定义的模式。乳胶纳米颗粒或蛋白质选择性地组装在这种图案的SAM上。
Coplanar nanostructures consisting of two different types of organosilane monolayers have been fabricated using scanning probe microscopes (SPMs) and served as templates for the area-selective immobilization of various materials. The first organosilane monolayer, which had been uniformly prepared on a substrate, was locally degraded through electrochemistry of adsorbed water at the junction of the monolayer and the SPM probe. This probe-scanned region chemisorbed molecules of the second organosilane, resulting in the creation of a self-assembled monolayer (SAM) confined to the SPM-defined pattern. Latex nanoparticles or proteins selectively assembled onto this patterned SAM.
