It has been usually noted that cortisol, a stress hormone, level should be regulated and measured condignly. In this research, Cortisol biosensor was demonstrated. Electrode of the biosensor was facilitated by fabrication metallic MXene whose characters show fascinating electrical conductivity and biocompatibility. For taking advantage of electrostatic interaction and van der waals force, PEDOT:PSS was brought. Modification of functional groups should be preceded so as to immobilization of antibody. Carboxyl groups can be reacted with amino groups through EDC chemistry, so that surface of MXene was modified with oxalic acid one of dicarboxylic acid. Furthermore, BSA was introduced to passivate non-specific materials. Among a bunch of methods in sensing system, EIS which indicates outstanding performance in selectivity and sensitivity. MXene is expected to be employed as a pleasant platform for biosensors. |
