Abstract
A method of fabricating hydrogel particles of controlled size within liposomes is provided, which entails encapsulating an effective amount of one or more hydrogel-forming substances in liposomes in a liquid medium, removing any unencapsulated hydrogel-forming substances from the liquid medium, adding initiator to the liquid medium and into the liposomes, thereby initiating reaction of the one or more hydrogel-forming substances, and removing any extra-liposomal initiators from the medium.
