Implantable Biosensor for Continuous Multi-Sign Monitoring
March 29, 2016 | Terry Sharrer
Profusa, Inc. (San Francisco, CA) has developed tiny implantable sensors (3-5 mm long, 500 microns in diameter) which can be injected under the skin to monitor biochemical changes. “Each biosensor is comprised of a bioengineered “smart hydrogel” (similar to contact lens material) forming a porous, tissue-integrating scaffold that induces capillary and cellular in-growth from surrounding tissue. The smart gel is linked to a light-emitting molecule that continuously signals the presence of a body chemical such as oxygen, glucose, or other biomarker.” A handheld reader senses the intensity of the fluorescent light to calculate a measurement.
