Abstract

AFM tips terminated with PMMA colloids are used to pattern molecules in both serial and parallel modes by allowing the polymer on the tip to swell under different humidity conditions. This extension of the dip-pen nanolithography technique provides an easy methodology to place inks on different substrates without the need to perform specialized tip alignment.

摘要

采用 PMMA 胶体封端的 AFM 针尖可用于串行和并行模式下的分子图案化，方法是使针尖上的聚合物在不同的湿度条件下溶胀。这种扩展的蘸笔纳米光刻技术提供了一种在不同基底上施加油墨的简单方法，而无需进行专门的针尖对准。
