“…For example, the electrical properties of deoxyribo-nucleic acid (DNA) How to cite this paper: Matsuo, Y., Ikeda, H., Kawabata, T., Hatori, J. and Oyama, H. [1]- [7]. For example, in the field of electrical devices, the investigations of DNA molecular wire and DNA based materials for switching devices have been carried out [8] [9]. It is also known that the DNA film exhibits proton conductivity in the humidified condition and can be used as the electrolyte of fuel cell [10] [11].…”

We have fabricated the fuel cell based on the tissue derived biomaterial "collagen" and investigated its proton transfer. It was found that "collagen" becomes the electrolyte of fuel cell in the humidified condition. The power density of the fuel cell becomes typically 8.6 W/m 2 in the 80% humidity. Further, these results indicate that collagen exhibits proton conductivity in the humidified condition. Both of proton conductivity and dielectric constant increase by the increase of humidity. From the analyses of the frequency dependence of AC conductivity, it was found that proton conductivity and the dielectric dispersion observed in the humidified condition are caused by the formation of the water bridge, which is bonded with the collagen peptide chain. Considering that hydration induces the formation of the water bridge and that increases proton conductivity and dielectric constant, it is deduced that proton transfer in the fuel cell based on collagen is caused by the breaking and rearrangement of hydrogen bond in the water bridge.

“…Reversible control of DNA hybridization by external stimuli is essential for the realization of DNA‐based machines, DNA switches, dynamic and self‐assembled DNA materials and nanostructures, and drug delivery . Thus, small‐molecule ligands whose DNA‐binding properties can be modulated through photochemical reactions, redox reactions, prototropic equilibrium, metal ion coordination, or a combination of these, can be employed as “switchable” ligands to control the stability of double‐stranded DNA and, in selected cases, induce hybridization or denaturation of DNA strands .…”

Copper(II)‐Controlled Molecular Glue for Mismatched DNA

Isothermal hybridization of two DNA strands bearing three thymine-thymine (T:T) mismatches can be brought about in the presence of a stoichiometric amount of a bis-naphthalene macrocycle, 2,7-BisNP-NH. This process can be reverted by addition of a Cu salt due to formation of a dinuclear metal complex which does not bind to DNA. Subsequent sequestration of Cu releases the macrocycle and restores the hybridization state of DNA strands, thus allowing implementation of a fast fluorescent two-state DNA switch.
