Flexible Hybrid Diamond Biosensor


Executive Summary


A unique fabrication method creates a new flexible and implantable thin film sensor for the biochemical, medical and neural engineering fields. This diamond-polymer hybrid demonstrates improved biocompatibility, durability and chemical sensing capabilities. 


Description of Technology


The rigidness and attachment incompatibilities of boron-doped polycrystalline diamond (BDD) limits its use as an implantable biosensor on soft tissue. A hybrid polycrystalline diamond/polymer thin film developed by MSU resolves these fabrication issues while improving dopamine detection capabilities in the presence of chemical interference. This new technology circumvents BDD’s rigidity by growing a thin flexible diamond film. It also creates a more secure bond by partially wrapping the polymer around the diamond.
