Grain growth manner, solid-state component for grain growth and device null for grain growth

摘要

PROBLEM TO BE SOLVED: To provide a method capable of promoting the crystallization of a biopolymer such as protein. ;SOLUTION: A silicon crystal 80 controlled in valence electron so as to enable the concentration of positive holes or electrons on its surface to be controlled according to the environment of a buffer solution 88 containing a biopolymer such as protein is brought into contact with the buffer solution 88, which is injected through the reverse face side of the silicon crystal 80 via a through hole 86 and held on the crystal 80 in the form of a droplet pendulous in the gravitational direction. The silicon crystal 80 is provided with plural grooves or holes 82a-f differing in size from one another, and the valence electrons in the crystal lie controlled so as to promote the crystallization of the biopolymer inside the grooves or holes. Thus, the crystal of the biopolymer is grown inside the grooves or holes 82a-f.;COPYRIGHT: (C)1998,JPO
