MUMBAI, India, Sept. 28 -- Intellectual Property India has published a patent application (202527125370 A) filed by Carleton University on December 11, 2025, for Organic Electrolyte-Gated Field Effect Transistor Biosensor.
Inventors include Prakash, Ravi; and Massey, Roslyn S..
The application for the patent was published on September 25, 2026, under issue no. 39/2026.
Abstract: An organic electrolyte-gated field effect transistor biosensor contains a microfluidic channel structure formed from a dielectric thermoplastic material. A biorecognition entity immobilized within the microfluidic channel allows the biosensor to detect the presence or concentration of an analyte in an electrolyte fluid placed within the channel. The dielectric material separates the microfluidic channel from the gate electrode and from the semiconductor material connecting the drain and source electrodes, and protects the gate electrode and the semiconductor material from direct contact with the electrolyte fluid in the microfluidic channel, to provide the biosensor with a high capacitance. Methods of fabricating the biosensor by monolithic 3D printing are also provided.
