Motivated by previous experiences in identifying active reaction zones on plant pheophytins of the so-called semi-derivative morphology, for the catalytic decomposition of hydrogen gas, this current research aimed for similarly suggestive sites within DNA base pairs which exist in all living matters. Verified by the 1st-principle quantum mechanical simulations and subsequent wet and dry hydrogen fuel cell experiments, the feasibility of room-temperature DNA-catalyzed hydrogen oxidation reaction was unambiguously established. This implies that very low-cost DNA-catalyzed fuel cells, which contain no expensive, CO-sensitive platinum on the negative electrode side, can be put to work under room condition and thus might be practically available in every household in the very near future.
