Abstract:
An apparatus for growing a crystal of a macromolecule contained in a solution, comprising:a substrate whose valence electrons are controlled so that the concentration of holes or electrons in a surface part can be controlled in response to the environment of the solution containing said macromolecule, whereinthe surface of said substrate has:a plurality of first solution storage parts for holding at least two types of solutions respectively,a plurality of second solution storage parts for holding the solution containing said macromolecule for growing said crystal, anda plurality of passages connecting said plurality of first solution storage parts with said plurality of second solution storage parts to allow distribution of the solutions, andthe valence electrons are so controlled at least in said second solution storage parts that the concentration of the holes or electrons in the surface part can be controlled in response to the environment of the solution containing said macromolecule.
