Charge trapping and untrapping of a bilayer system Pt/poly[Ru(Vbpy)3] / poly[Fe(Vbpy)j] was studied. It was shown that electron diffusion in the iimer bilayer film is an important rate-limiting factor.

Bokor and coworkers fabricated a CNT transistor array for label-free DNA biosensors [208]. To support specific adsorption between CNTs and DNA, a copolymer containing an activated ester functionality, poly[methyl methacrylate-co-poly(ethyleneglycol)methyl methacrylate-co-N-succinimidyl methacrylate] (abbreviated as N06), was synthesized and electrostatically immobilized on the CNT transistor array. N-Succinimidyl ester groups that composed one part of the copolymer allowed the aminated single-strand DNA sequences to bind covalently onto the surface of CNTs (Fig. 11). After the attachment of DNA, the hysteresis of the /(i-Fg curve was significantly increased as a result of the increase in the charge traps on the CNTs. By measurement of the fa-Fg curve, DNA hybridization can be easily and rapidly detected.
