Tissue-integrated Biosensors Tissue-integrated biosensors are at the center of Profusa’s proprietary technology. Measuring 2-5 mm in length, and 200-500 microns in diameter, each Profusa biosensor is inserted using a hypodermic needle. Once injected, the soft tissue-like biosensor (similar feel to a soft contact lens) ...
The results indicate that the system has potential for further development as a sensitive SPR‐based biosensor for endocrine‐disrupting chemicals. This article is protected by copyright. ...
A low-cost optical sensor built-in strip has been developed from a composite obtained with application of in-situ chemical polymerisation, using polyaniline in the emeraldine oxidation state, doped with HCl onto poly(ethylene terephthalate) (PET) film, used to measured the pH of water. ...
Discussed are findings that demonstrate that our novel chalcogenide-based micro-fluidic device can be used as highly sensitive refractive index sensors.Keywords: chalcogenide glass, thin films, waveguide, refractive index sensors, compact micro-disk resonators, photonic integration, refractometry, absorption spectroscopy, microfluidics, lab-on-a-chip, molecular sensors, nanotechnology, ...
The sensor project is an offshoot of the Center for Innovative Food Technology, which recently conducted a study of instrumentation needs and trends. Chemical sensing and biosensors are among the most in-demand devices, but the greatest need is for a more fundamental measure: level sensing. ...
