title: A method for patterning purple membrane using self-assembled monolayers.
abstract: A method for patterning purple membrane on a substrate is described. This method involves the use of patterned self-assembled monolayers. The quantity of purple membrane adsorbed to glass terminated by various self-assembled monolayers was measured using angle resolved X-ray photoelectron spectroscopy. It was determined that purple membrane adsorbs to unmodified glass and amine-terminated glass surfaces. Hydrocarbon- and fluorocarbon-terminated glass inhibit the adsorption of purple membrane. To demonstrate a potential patterning methodology, an amine-terminated self-assembled monolayer (SAM) was photochemically substituted for a hydrocarbon-terminated SAM using UV radiation. Future work will involve the use of UV radiation in conjunction with a lithographic mask so that specific PM adsorption sites can be defined on a substrate.
