Abstract
A modified isolated polypeptide comprising an amino acid sequence encoding a photocatalytic unit of a photosynthetic organism being capable of covalent attachment to a solid surface and having a photocatalytic activity when attached thereto is disclosed.
Claims29
A modified isolated polypeptide comprising an amino acid sequence of a Photosystem I P700 chlorophyll a apoprotein A2 (psa B) polypeptide of a Photosystem I (PSI) unit of a photosynthetic organism, said amino acid sequence mediating covalent attachment of said PSI unit to a solid surface and maintaining a photocatalytic activity of said PSI when attached to said solid surface.
An optoelectronic device comprising a first electrode, a second electrode, and at least one layer of photoactive nanoparticles interposed between said first electrode, wherein at least one of said first electrode and said second electrode is light transmissive, and wherein said photoactive nanoparticles comprise conducting solid surfaces covalently attached to PSI units of photosynthetic organisms.
A method of fabricating an optoelectronic device, comprising covalently attaching PSI units of photosynthetic organisms to at least one first electrode, thereby providing a layer of photoactive nanoparticles on said least one first electrode, and depositing at least one second electrode on said layer of photoactive nanoparticles.
