DuPont Biosensor Materials

Overview

DuPont Biosensor Materials are specifically designed for use in medical monitoring, diagnostics, drug delivery, food and beverage testing, and environmental sensors.

The line of printable conductive materials improve sensitivity & selectivity of new sensor designs with fine lines, thin layers, and high conductivity.

Key features of DuPont Biosensor Materials:

  • Printed on flexible substrates products are compact, lightweight, environmentally friendly, inexpensive and lend themselves to highly efficient manufacturing processes.
  • Can be folded, twisted, bent around corners or bonded to any surface making them ideal for applications where flexibility is needed.
  • Printed on ceramic substrates, PTF products are especially suited to harsh environments, e.g., chemicals, temperature, where a biosensor is expected to have a longer life.

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
  • Microfluidic and chip designs for drug screening and DNA sequencing
  • Trace/heavy metal and food freshness sensors
  • Medical devices including heart pacemakers and hearing aids

Products

DuPont Biosensor Materials build on core competencies in materials science, chemistry and fine particle technology. Products 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.
  • Compositions include ceramic Green Tape™ used in hearing aids and other medical devices.
