The present invention relates to a porous alginate-based hydrogel, a method for preparing the same, and a drug delivery system using the same. 2 It is characterized in that porosity is given to the hydrogel as gas is generated, and the resulting porosity is a drug delivery system that induces drug release, which suppresses rapid drug release in the initial stage and has sustained-release drug release characteristics in the pharmaceutical and cosmetic fields. can be useful for |
