Reading biochemistry with infrared light.

Spectroscopy is a well-established technique which is already used across many different industries to derive the structural and chemical composition of a sample in any form, solid, liquid, or gas.


The atoms in a molecule are always moving. Spectroscopy detects changes in motion caused by electromagnetic radiation absorbed by a molecule. You can identify a molecule from its own unique signature change, called its ‘spectrum’.


Biological samples are made up of many different molecules. Their composition makes the spectral information rich, but complex because they overlap. Environmental contaminants also affects samples, which is particularly problematic with biological samples. As a result, it has been difficult to split the spectrum into individual components. Through advances in computational power and data analysis, however, AIRA Sciences has created an algorithm which removes the biological and environmental noise and targets specific biomarkers to provide a reliable risk assessment for cancer screening.

AIR-DS is a UKCA marked in vitro diagnostic medical device, developed in accordance with IEC 62304 and under an ISO 13485 certified quality management system. In the US, a CLIA certified laboratory will offer a laboratory developed test (LDT) with AIR-DS Lung Test. It has not been cleared or approved by the FDA.
