A 2,4,6-trinitrotoluene (TNT) molecule recognition peptide-modified potentiometric device was developed in a multiparallel way using microelectrodes. The change in potential caused by the explosive target and recognition peptide was monitored in real-time sensorgrams through our laboratory-built analysis system. The peptide-modified microelectrode-based potentiometric device demonstrated the highly selective and sensitive sensing of the TNT molecule over other aromatic analogues.
