Microcontact printing is a remarkable surface patterning technique. Developed about 10 years ago, it has triggered enormous interest from the surface science community, as well as from engineers and biologists. The last five years have been rich in improvements to the microcontact printing process itself, as well as in new technical innovations, many designed to suit new applications.

The goal of this project is the evaluation of chemically modified PDMS (or other stamp materials) for applications that require contact between two macroscopic surfaces. Applications are foreseen in patterning and microcontact printing through monolayer transfer, patterning through surface catalysis, and supramolecular surface adhesion. A focus is on high resolution and high materials versatility.
