  • Carbon nanofiber sensor for non-enzymatic glucose detection and methods of glucose detection using such carbon nanofiber sensor
    Patent number: 11035820
    Abstract: A general methodology for the development of sensitive and selective sensors that can achieve a low cost detection of glucose without using enzymes is disclosed. The method uses carbon nanofiber (CNF) array electrodes for the electrochemical detection of glucose. CNFs grown by plasma enhanced chemical vapor deposition (PECVD) with diameters ranging from 13-160 nm and a height of approximately one micrometer are preferred. The CNFs have a sensitivity of 2.7 ?A/mM cm2 and detection limit of 2 mM. Also provided are methods of preparing the CNF sensors and kit components. Methods of using such CNF sensors for detecting target agents, particularly glucose, are also provided.
