Alira Infrared Biosensing

Our Mission

Alira Infrared Biosensing is dedicated to improving molecule analysis using mid-infrared spectroscopy and machine learning. Unlike near-infrared spectroscopy, which only measures absorption band overtones, our quantum cascade laser system measures the fundamental absorption bands in the mid-infrared region, allowing for the most specific, sensitive measurements. We're working to design our sensor system to your exact specifications, whether that be for a sensor integrated into a production line for continuous monitoring or a handheld device simple enough for anyone to use. Our system is extremely adaptable, and we're excited to work with you and to meet your needs.

The Technology

The components behind our system.

Non-contact

Most biomarker analysis involves something disposable -- a test strip, an assay kit, or a cuvette, costing thousands of dollars per year. Our system can take as many measurements as needed, even continuous, with no increased cost or contact thanks to mid-infrared spectroscopy.

Robust

The sensor has no moving parts, requires no calibration, and needs no special training. With machine learning algorithms and a few seconds of scanning, drifting backgrounds can be overcome, providing an accurate measurement with no extra fuss.

Accurate

Thanks to quantum cascade lasers and machine learning, our system sensitively and selectively measures molecules. Current near-infrared spectroscopy solutions only measure overtones of absorption bands, but the fundamental bands lie in the mid-infrared region that we measure.

About

The history of the quantum cascade laser (QCL) and Alira.

  • Old QCL

    1994

    Invention

    The QCL was invented at Bell Labs, opening the possibility to have a high power light source at many wavelengths throughout the mid-infrared (MIR) region.

  • Continued Development

    2006

    Further Development

    Key researchers, including Professor Claire Gmachl at Princeton University, significantly improved the QCL by increasing its range and power.

  • Miniaturization

    2015

    Miniaturization and Detection

    A miniature spectroscopy system was developed by graduate students in Claire Gmachl's lab, including Alexandra Werth and Sabbir Liakat.

  • Commercialization

    2018

    Commercialization

    Alira Infrared Biosensing is formed to evolve the work done in Claire Gmachl's lab to a commercializable product, investigating applications in healthcare and industry.
