Abstract
This chapter will focus on the fabrication and morphological and electrochemical characterization of silicon carbide (SiC) nanostructures (particles, fibers, laminates, thin films) used to develop electrochemical glucose biosensors. Glucose oxidase enzymes coimbedded in a conductive polymer with silicon carbide nanostructures exhibit high sensitivity, quick response time, and enhanced limit of detection and durability. SiC nanoparticles (SiCNPs) spin-coated-thin-films and SiCNPs electrospun-nanofibrous-membranes have been implemented as glucose-sensing electrodes, and a comparative analysis of SiCNPs with both ENFMs and SCTFs has been conducted. Prior research has shown that conducting polymers could be utilized as a mediator for the detection of glucose. This is presumably due to direct electron transfer between glucose oxidase and the conducting polymer, which is an oxygen-independent detection mechanism. This chapter presents the feasibility of using electrodes containing embedded SiC nanostructures as an emerging approach to fabricating highly sensitive glucose biosensors.
