MICROGRAIN FILM AND PROCESS FOR PRODUCING THE SAME

摘要

It becomes possible to provide a film wherein micrograins are regularly arranged at a high density and a high accuracy. This micrograin film comprises a substrate and micrograins made of a plural number of proteins which are regularly aligned on the surface of the substrate in the plane direction parallel to the surface of the substrate. Each of these proteins has a plural number of first binding units and one or more second binding units respectively made up of condensed amino acids. Each first binding unit is bonded to other first binding units having the adjacent micrograins, while the second binding units are bonded to the substrate. At least part of the condensed amino acids constituting the second binding units are substituted.
