Core-shell crosslinked hyaluronic acid gel particles, production method for same, and medical material

摘要

These core-shell crosslinked hyaluronic acid gel particles are core-shell crosslinked hyaluronic acid gel particles having higher equilibrium swelling ratio at the surface than at the center, an inflection point being present on the curve of change of the equilibrium swelling ratio plotted from the center to the surface, wherein the probe pushing force to a depth of 800 nm from the surface is 20 nN or less.
