MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202431095009 A) filed by Tezpur University, Tezpur, Assam, on Dec. 3, 2024, for 'fabrication of a carbon nanotube-based enzyme field effect transistor (cnt-enfet) for the detection of sarcosine.'
Inventor(s) include Saikia, Onishaa; and Dutta, Jiten Chandra.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a carbon nanotube enzyme field effect transistor (CNT ENFET) based system for detection of sarcosine analyte and its method of fabrication. The system comprisesa working electrode comprising Indium Tin Oxide (ITO) coated glass substrate with deposited PEI-doped multiwalled carbon nanotubes (MWCNT) thereon; and said PEI-doped MWCNTbased transporting layer having an insulating layer comprising of High-? dielectric Nb2O5thereonand operatively connected nanocomposite modified sensing layer comprising DMSO treated PEDOT: PSS-MWCNT-CHIT having Sarcosine oxidase (SOx) enzyme immobilized thereon; said immobilized Sarcosine oxidase (SOx) enzyme providing for catalytic activation of demethylation of sarcosine with liberation of H2O2 contributes toward the acid/base reactions at the electrode surface enabling quantifiable variation of pH at gate surface of said sensing layer based sarcosine analyte detection in presence of Ag/AgCl reference electrode, at low limit of detection of 0.98 nM."
