Chemical Sensors


IOS has extensive experience in the development of various optics-based chemical sensors and advanced monitoring instrumentation with intelligent decision making capabilities. Our optochemical sensor research includes the development of applications and products using such technologies as localized surface plasmon resonance (LSPR) for bioassay, surface enhanced Raman spectroscopy (SERS) for identification and monitoring, terahertz spectroscopy for the standoff detection of hidden threats, and droplet based microfluidics for laboratory-on-a-chip automation of chemical and biochemical assays. The chemical sensor program utilizes a variety of nanotechnolgies to implement highly sensitive assay systems. One product line emerging from research in this area is a collection of water soluble, biocompatible quantum dots that fluoresce over a wide range of visible wavelengths and that are useful for a variety of optical labeling and assay applications.

IOS has developed chemical sensors for:

Volatile and semivolatile organic compounds (VOCs and SVOCs)
Organic pollutants, toxins, and microorganisms
Water and air monitoring
Standoff detection of explosives
