The present invention relates to a hydrogel bubble and a method for preparing the same, which can produce a polymer bubble in a hollow bubble form to support a drug therein. The method for producing a hydrogel bubble according to the present invention is biocompatible and economical since no crosslinking agent or dispersant is used. In addition, the hydrogel bubble according to the present invention is empty, the inside is very excellent in carrying capacity of water-soluble and water-insoluble drugs, cosmetics, enzymes and the like. The method for producing a hydrogel bubble according to the present invention is simple because it is made through a single reaction in one reaction vessel, and the method for producing a hydrogel through the present invention is easy to control the thickness of the shell by changing the molecular weight and concentration of the polymer. |
