Our Gas SPR technique is useful for a variety of applications:

  • Fundamental solid-gas interface studies
    Unlike many other current SPR instruments, BI’s high-precision SPR instruments are designed with the capability for gas phase detection. They provide superior results for small-molecule detection and help to characterize polymers and thin films at solid-gas interfaces. By coating a metal film with sensing materials such as polymers, adsorption of the molecules onto the sensing materials can be detected by observing SPR angle shift. This feature enables the study of various molecular binding processes onto a modified surface from the gas phase.
  • Detection of Toxic Molecules
    The use of fossil fuels has raised growing environmental concerns about air quality and toxic molecules in the air we breathe. Because BI’s SPR instruments are sensitive to processes occurring at the solid-gas interface, they can detect vapor interactions with various monolayers of molecular receptors. This paves the way for chemical vapor sensing and gas-phase sensor development, and has implications in both environmental safety and the detection of chemical warfare agents.
  • Chemical Analysis for Medical Research
    Here at BI, our gas phase SPR techniques can also be applied by creating detectors that analyze chemical components in vapors such as human breath. Using these SPR methods could have a huge significance for a variety of health-related studies and medical research overall.
