In the December 9 issue of Advanced Functional Materials, Wang et al. report on the nanoscale chemical surface patterning of different chemical species (amine, thiol, aldehyde, and biotin) in independent nanopatterns by the iterative application of thermochemical nanolithography. Due to the unique chemical stability of the patterns, the resultant substrates can be stored for weeks and subsequently be used for the selective attachment of nanometer-sized objects, such as proteins or DNA, using standard chemical protocols. This work is enabled by nanoscale thermal processing tools developed by Mechanical Science and Engineering professor William King and post doctoral associate Zhenting Dai. Professor King is also affiliated with the Beckman Institute, the Micro and Nanotechnology Laboratory and the Center for Nanoscale Chemical-Electrical-Manufacturing Systems (NanoCEMMS).
