|発明の名称||MAGNETISM-IMPARTING TYPE HYDROGEL THIN FILM|
PROBLEM TO BE SOLVED: To provide a new magnetism-imparting type hydrogel thin film moved and fixed by magnetic force not only in a vapor phase, but also in a liquid, e.g. being utilizable as a repairing material for a lesioned part in fetal surgery treated in a liquid phase called amniotic fluid and to provide a new magnetism-imparting type hydrogel thin film moving and fixing existing hydrogel by magnetic force and improved in maintenance of a planar shape even in a culture solution and being effective for both-side culture.
SOLUTION: The thin film is composed of a rehydrated product of a vitrified matrix gel thin film containing an extracellular matrix component as well as magnetic beads.
