Abstract

We report a new inkless catalytic muCP technique that achieves accurate, fast, and complete pattern reproduction on SAMs of Boc- and TBS-protected thiols immobilized on gold using a polyurethane-acrylate stamp functionalized with covalently bound sulfonic acids. Pattern transfer is complete at room temperature just after one minute of contact and renders sub-200 nm size structures of chemically differentiated SAMs.

Professor Emeritus of Chemistry

Dr. Toone is a physical organic chemist who studies relationships between structure and activity in the context of biology. Currently active programs exist in biocatalysis/applied enzymology, ligand binding and the activity of water, and the synthesis of novel donors of nitric oxide. The study of these problems makes use of synthetic organic chemistry, traditional enzymology, isothermal titration microcalorimetry, and the techniques of directed evolution.
