제목 Effects of improved pore structure and electrical conductivity of carbon nanofibers for an efficient biosensor
초록 The polyacrilonitrile-based activated carbon fibers (ACFs) were prepared by electrospinning and physical activation as a glucose sensor material. The silica and carbon nanotube (CNT) were embedded as activation agent and conductive filler. The pore structure in carbon fibers was obtained by removing silica using HF. The concentration of glucose was determined at various concentration of glucose through current-voltage curves. The concentration of glucose was decided by obtained electrochemical results with high sensitivity. This result can be interpreted by the enlarged surface area by activation process worked for increasing the reaction area between glucose oxide and glucose and the improved electrical conductivity by CNT additive maximize the transfer of electrical resistance change occurred on the surface of ACFs. In conclusion, the highly sensitive glucose sensor was obtained based on effects of improved pore structure and electrical conductivity by silica and CNT additives.
