Transparent conducting carbon nanotube (CNT) films were fabricated on the glass, which have the electrical conductivity and the optical transparency [1]. The singlewalled CNT (SWNT) film was investigated with gold-hybridization by a simple and cheap process, which electroless reduction of gold ions on the SWNT networks by the vacuum filtration can enhance their electrical conductivity without a substantial change in their transmittance of visible light. The gold-fabricated CNT film as a highly conductive electric device was also utilized for the efficient immobilization of the gold binding polypeptide (GBP) for detecting the biomolecular sensing [2]. The organophosphorus hydrolase (OPH) was used as a model protein for the specific immobilization of GBP-fusion protein onto the gold surface of the CNT film. As subsequent binding of GBP-OPH fusion protein and target molecules, electric conductance was reduced to compare with the value before binding. This phenomenon is suggesting that electrical signals represent the specific detection of organophosphorus pesticides [This work was supported in part by the IT Leading R&D Support Project from the Ministry of Knowledge Economy through KEIT].
