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

Features

A new lab-on chip device for detecting ammonia in biomedical and industrial applications. The modification of PDMS (polydimethylsiloxane) composite film is done by ninhydrin integration. The lab-on-chip device developed by integrating the ninhydrin-PDMS into a microfluidic device. It supports optical specific detection of NxHy groups (NH3 and amino acids). Light emitting diode and photoresistor are integrated to measure changes in absorption.

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

Current Status

Development stage: TLR4-5

Patent status: PCT application in March 2019
