Message-ID: <19991027172855.55100.qmail@hotmail.com> I am experimenting with several materials to use as insulation for a microelectrode array. To test adhesion to silicon I need to be able to pattern these materials. Polyimide can easily be patterned using photoresist. Does anyone know a method for patterning polyurethane or PMMA? Thanks for your help. Jolyn Twelves Bioengineering Department University of Utah 50S.
