Noninvasive Glucose Measurements
InLight Solutions is developing non-invasive devices that use near
infrared (NIR) optical spectroscopy and multi-variate analysis to
make quantitative and qualitative measurements. When applying
the technology to measuring glucose, it is the product engineering and the
multi-variate software algorithms that are critical to producing accurate
results. Since glucose molecules look very much like water molecules, we design
our optics and our software to clearly distinguish the target molecule from
anything else. This enables us to make dependable measurements.
The devices are made up of three components: a light source, an optical detector,
and a spectrometer. Simply put, the light source shines light into the skin. Much of the
light escapes but some bounces back and can be analyzed by the spectrometer
with subsequent measurement by the detector. By measuring differences between
the light that was sent into the skin and the light that the detector collects,
the system can be programmed to selectively analyze a particular molecule.
Each molecule responds differently to the light so we can distinguish one
from the other by their particular vibration characteristics. The entire system
is optimized for accurate quantitative
measurements of glucose concentration.
InLight manufactures prototypes for its research partner and will perform
final assembly and test for the product line upon FDA approval.
