Abstract

The pigment-protein complex of photosystem 1 (PS1) isolated from cyanobacterium Synechocystis sp. PCC 6803 has been adsorbed on a solid mesoporous film made from TiO ₂ nanoparticles. was on The TiO ₂ film supported on a glass substrate with a surface area of 1 cm ² adsorbs up to 0.045 nmol of PS1. PS1 molecules are distributed in the pores of the mesoporous support. Immobilization has an insignificant effect on the optical and photochemical properties of PS1. A reversible photoinduced EPR signal from the oxidized primary electron donor P700 of immobilized PS1 has been detected. It has been shown by photo-electrochemical methods that the photoexcitation of PS1 results in electron injection from PS1 to the conduction band of TiO ₂.
