Production of ultra-thin film reactor with immobilised proteins

摘要

Production (A) of an ultra-thin film reaction with immobilised proteins comprises immersing a solid carrier in an aqueous solution and an aqueous solution of a polyion, alternately. The polyion charge is opposite to the charge on the protein and the product has a structurally controlled ultra-thin film with molecular precision content, on the carrier. Also claimed are: (1) a production (B) of an ultra-thin film reactor supplying /- 2 proteins, by: (a) immersing a solid carrier with an electrically charged surface in an aqueous solution which contains polyions or protein with the opposite charge, to reverse the charge on the surface by neutralisation and re-saturation, (b) immersing in a different aqueous solution containing polyions or protein of the opposite charge, to reverse the charge again, by neutralisation and re-saturation and (c) repeating the steps; (2) a process for chemically reacting substrate molecules, using a carrier with several immobilised thin films, obtained by (A) or (B), and (3) a process for chemically reacting substrate molecules by immobilising a thin film of protein on a solid carrier which has a separation function, obtained by (A) or (B), and separating the substrate and the product of the reaction.
