Novel mesoporous carbon sheets for electrochemical sensing of biological compounds

A highly sensitive biosensor electrode was designed using a novel mesoporous carbon (MPC)-sheet. In this study, the MPC-sheet was prepared by the hard-template method using a mesoporous silica (MPS) sheet. The MPS sheet has unique characteristics such as thin shape, porous structure, and highly capacity as an absorbing material. The shape of synthesized carbon materials was similar with the template MPS sheet which was approximately 1-2 μm width and 100 nm a folded thickness. Surprisingly, the physicochemical properties of MPC-sheet were demonstrated different characteristics depending on the template materials. The MPC-sheet-modified electrode demonstrated excellent electrocatalytic activity for the simultaneous determination of biological compounds.
