Tuning characteristics of Co3O4 nanofiber mats developed for electrochemical sensing of glucose and H2O2
Source abstract
Abstract
Abstract Nano-crystalline Co 3 O 4 nanofibrous mats were fabricated by calcining the precursor nanofibers obtained by electrospinning of a sol comprising of a unique polymeric binder poly(2-ethyl-2-oxazoline) and cobalt acetate tetrahydrate in water. The influence of the calcination temperature used for the synthesis of the oxide nanofibers from the xerogel fibers on various physico-chemical properties of the former was studied. The Co 3 O 4 nanofibers obtained at 400 °C had the highest electrochemical sensitivity towards glucose and H 2 O 2 . Further, the results prove that Co 3 O 4 nanofibers can be used for the detection of glucose and H 2 O 2 concurrently as the response times taken by these moieties are different. Therefore, one can differentiate the concentration of glucose and H 2 O 2 by analyzing the signals obtained after the respective response time and this multiple sensitivity of Co 3 O 4 can be applied in the field of biosensors.
