Maskless electrochemical patterning of gold films for biosensors using micromachined polyimide probes

Abstract

This paper explores the electrochemical patterning of thin metal films using a scanning probe tip as an electrode. In particular, a masking nickel film is etched to reveal a gold pattern to which biomolecules like liposomes and proteins can be attached after treatment with functionalized self assembled monolayers (SAMs) of gold-thiolate. The machining is… (More)
