MUMBAI, India, Aug. 10 -- Intellectual Property India has published a patent application (202641031227 A) filed by Kanchan, Aadya on March 16, 2026, for An Optical Device For Rapid Reagent Free Testing Of Lipidconcentration.
Inventor includes Kanchan, Aadya.
The application for the patent was published on July 31, 2026, under issue no. 31/2026.
Abstract: The present invention is related to an optical device for rapid reagent free testing of lipid concentration. This optical sensing device comprises a polydimethylsiloxane (PDMS) microfluidic channel maintaining laminar flow, integrated with an RGB sensor (TCS34725) and a multichannel spectral sensor (AS7265x Triad) capturing wavelength-specific scattering responses from 410 nm to 940 nm across visible and near-infrared regions. Lipid-induced turbidity and wavelength-dependent scattering produce distinct spectral fingerprints corresponding to lipid concentration, with maximum discrimination at 410 nm, 535 nm, 645 nm, and the near-infrared region. An ESP32 microcontroller processes optical signals from both sensors, and a protective enclosure isolates the optical path from external interference. The device achieves approximately 85–90% detection accuracy within five minutes, validated using blood-mimicking fluids and human plasma samples. Operating without biochemical reagents, the device provides a portable, low-cost platform for point-of-care cardiovascular risk screening and mass screening of metabolic health in resource-limited settings.
