Title:
NANOPARTICLES AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2017/047364
Kind Code:
A1
Abstract:
Each nanoparticle according to the present invention is composed of a molecular assembly that contains an amphiphilic block polymer having a hydrophilic block and a hydrophobic block. It is preferable that the amphiphilic block polymer has biodegradability. Nanoparticles according to the present invention are obtained by granulating an amphiphilic block polymer in the presence of an amino acid having an isoelectric point of 7 or less. In one embodiment of the present invention, granulation is carried out by bringing a solution containing the amphiphilic block polymer or a dried product of the solution into contact with an aqueous liquid. By having the amino acid having an isoelectric point of 7 or less contained in at least one of the solution containing the amphiphilic block polymer or the aqueous liquid, granulation is able to be carried out in the presence of the amino acid.
