Photochemically induced protein crystallization by protein's multiphoton excitation based on enhanced field of localized surface plasmon resonance (LSPR) of gold nanostructures was investigated. As strong photons-molecules coupling fields, gold nanostructures composed of nanoblocks ware used. Crystallization probability depends on the excitation photon fluence, which indicates 3 photons absorption process occurred. We developed crystallization plates equipped with strong photon-molecule coupling field made of gold thin films that enhances crystallization frequency.
