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.

 

Key Benefits

  • Diamond sensor with flexibility
  • Strong and secure diamond attachments
  • One sensor to detects many chemicals
  • Biocompatible Young’s modulus
  • Improved signal to noise ratio

 

Applications

  • Brain implant
  • Explosive chemical detection
  • Sweat chemical detection
  • Optogenetics
