Core-shell type crosslinked hyaluronic acid gel particles, method for producing the same, and medical material

摘要

The core-shell type crosslinked hyaluronic acid gel particle according to the present invention is a core-shell type crosslinked hyaluronic acid gel particle having a higher equilibrium swelling ratio than the center and having an inflection point in the change curve of the equilibrium swelling ratio from the center toward the surface. The probe pushing force from the surface to a depth of 800 nm is 20 nN or less.
