POLYMER COMPOSITE MICRO-OPTICAL SENSING PLATFORM FOR AMMONIA (NH3) TOXIC GAS

A very powerful and low cost technology for ammonia sensing in biomedical and industrial applications.

Ammonia sensor market opportunity

  • NH3 is one of the largest-volume synthetic chemicals produced in the world (~200 M metric tons in 2018)
  • 88% of NH3 production is used for fertilizers
  • Other NH3 sources include automotive and mining industries, livestock, food and pulp & paper industries, refrigeration, oil industry
  • Gas sensors global market = $1.3 B by 2023
  • NH3 segment = $73.3 M in 2023
  • NH3 = 75% of gas sensor market for water & wastewater treatment ($70.4 M in 2023)
  • Biomedical market:
    • NH3 is a by-product of protein metabolism
    • Unmet need for NH3 breath analyzer in point-of-care diagnostic of liver/kidney diseases, H. pylori infection, stomach/lung cancers
    • Global market for sensors in point-of-care applications = $7.67 billion in 2023

A new ammonia sensing platform

  • Modification of PDMS (polydimethylsiloxane) composite film by ninhydrin integration
  • Lab-on-chip device developed by integrating the ninhydrin-PDMS into a microfluidic device
  • Optical specific detection of NxHy groups (NH3 and amino acids)
  • Integrated light emitting diode and photoresistor to measure changes in absorption
  • Technology developed by Dr. Muthu Packirisamy (Department of Mechanical and Industrial Engineering, Concordia University)
  • Development stage: TLR4-5
  • Patent status: PCT application in March 2019

Multiple competitive advantages

  • Miniaturization for integration in wearable devices (emerging market)
  • Portable, small size, low weight
  • Low manufacturing cost
  • Disposable (or not)
  • USB connection or wireless options
  • High sensitivity (adjustable to ppb or ppm range)
  • High signal to noise ratio
  • Ammonia specific detection

Business opportunity

  • Searching for industrial partners to develop ammonia sensing products according to specific market needs
  • Technology also available for in-licensing
