Description
Summary:•Synthesized Cobalt oxide (Co3O4) sheets are exfoliated into layered nanosheets.•Surface of the nanosheets are uniformly webbed by polyaniline nanofibers (PANINFs).•Co3O4@PANINFs material showed electrocatalytic property in electrochemical study.•The nanohybrid material is used for the fabrication of efficient glucose biosensor. A novel glucose biosensor was designed using cobalt oxide (Co3O4) nanosheets patterned by π-conjugated polyaniline nanofibers (PANINFs). A facile synthesis process was conducted to obtain cost-effective and ecofriendly mesoporous Co3O4@PANINFs hybrid nanomaterial for the first time. The Co3O4@PANINFs on glassy carbon electrode (GCE), working as a biosensor electrode based on electrochemical technique, showed electrocatalytic activity to glucose with sensitivity of 14.25μAmM−1cm−2, linear range from (0.1 to 8) mM, minimum detection limit of 0.06mM, and response time
