摘要： Provided is a method for easily and efficiently producing encapsulated substance vesicles wherein a substance is encapsulated in the cavity of vesicles obtained by polymer self-assembly. Empty vesicles that have membranes comprising a first polymer that is a block copolymer with uncharged hydrophilic segments and a first kind of charged segments and a second polymer with a second kind of charged segments that carry a charge that is the opposite of said first kind of charged segments as well as spaces that are enclosed by said membranes are mixed in an aqueous medium with the substance that is to be encapsulated in the spaces.

摘要： The purpose of the present invention is to provide an electrostatically bonded vesicle which bears disulfide bonds or thiol groups. The present invention relates to a vesicle having a membrane which is formed from both a first polymer of (a) or (b) and a second polymer of (c) or (d) (with the proviso that a combination of (b) and (d) is excepted) and in which the cationic segment and anionic segment of the polymers are partially crosslinked. First polymer: (a) a block copolymer (I) having both an electrically non-charged hydrophilic segment and a cationic segment, (b) an amino acid polymer (I) having a cationic segment. Second polymer: (c) a block copolymer (II) having both an electrically non-charged hydrophilic segment and an anionic segment, (d) an amino acid polymer (II) having an anionic segment.
