METHOD FOR PRODUCING BIOMATERIAL COATING LIQUID, AND COATING LIQUID PRODUCED THEREBY

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a biomaterial coating liquid having a low concentration, which makes it possible to carry out coating on various base materials without deteriorating activity of a biomaterial.SOLUTION: A coating liquid suitable for a biomaterial composed of a low-concentration silica sol solution is obtainable by using basic peptide as a reaction catalyst, and subjecting silicon alkoxide to hydrolysis by still-standing interface reaction under a neutral condition.
