Multifunctional thin film surface

DWPI Title: Preparation of multifunctional thin film surface involves electrodepositing aryl-onium molecule on surface of electrode, electrochemically grafting another molecule to electrodeposited molecule, treating surface with cells, and reacting
Abstract: A thin film with multiple binding functionality can be prepared on an electrode surface via consecutive electroreduction of two or more aryl-onium salts with different functional groups. This versatile and simple method for forming multifunctional surfaces provides an effective means for immobilization of diverse molecules at close proximities. The multifunctional thin film has applications in bioelectronics, molecular electronics, clinical diagnostics, and chemical and biological sensing.
Use: Preparation of multifunctional thin film surface for bioelectronics, molecular electronics, clinical diagnostics, and chemical and biological sensing.
Advantage: The method is versatile and simple and effectively immobilizes diverse molecules at close proximities.
Novelty: A multifunctional thin film surface is prepared by providing conducting or semiconducting electrode, electrodepositing 1st aryl-onium molecule having 1st functional group on surface of electrode in which 1st functional group is selective to 1st target analyte to provide immobilized film of 1st aryl-onium molecule, electrochemically grafting 2nd molecule having 2nd functional group the electrodeposited 1st aryl-onium molecule in which 2nd functional group is selective to 2nd target analyte and is different than 1st functional group, and electrochemical grafting provides a submonolayer.
