Conductive Inks for Biosensors

DuPont offers a broad family of conductive inks and materials for biosensors that offer flexibility, high density and can be highly customized. These materials improve sensitivity and overall performance of new sensor designs with fine lines, thin layers, and high conductivity.

DuPont Biosensor Materials include:

  • Electrically conductive compositions including silver, gold, and carbon for lines and contact pads.
  • Silver/Silver Chloride compositions used as electrodes for amperometric sensors, potentiometric sensors, and iontophoretic drug delivery devices.
  • Precious metal-based compositions for working electrodes in amperometric sensors used in analyte detection.
  • Fired-on and other customized materials - Contact Us for details

Key Applications

  • Enzyme-based amperometric biosensors for metabolic analyte testing (e.g., blood glucose, cholesterol, lactate)
  • Potentiometric sensors for selective ion detection of body electrolytes
  • Iontophoretic devices for drug delivery
  • Microfluidics for drug screening and DNA sequencing
  • Medical devices including hearing aids - see information on DuPont™ GreenTape™ low temperature co-fired ceramic (LTCC) systems for details on this application
  • Fired-on materials can also be used in biosensor applications. Contact us for more details

Key Features

  • Highly conductive
  • Ideal for applications where flexibility is needed.
  • When printed on flexible substrates, our materials are lightweight, and lend themselves to highly efficient manufacturing processes.
  • Broad range of product types
  • Formulations can be customized for specific uses
