Latest Patents

Valkiainen's latest patents include a multilayered structure comprising an enzyme layer, which is suitable as an electrode in a power source. This structure features a conductive laminar layer and an enzyme layer containing a dry enzyme capable of oxidizing or dehydrogenating carbohydrate material under suitable conditions. The design ensures that the enzymatic anode layer and the fuel-containing layer do not interact during production, allowing for stable storage and increased utility of the power source over extended periods. His second patent involves thin film structures, which consist of a substrate with a thin conductive layer containing an oxidizing enzyme mixed with an electron transfer mediator. This thin layer is protected against wetting, enabling storage in dry conditions while remaining sufficiently porous for immediate activation upon contact with an aqueous solution. These thin films can be utilized as cathodes in electrochemical fuel cells.
