Title:
NANOPARTICLE FOR PHOTOACOUSTIC IMAGING
Document Type and Number:
WIPO Patent Application WO/2016/143017
Kind Code:
A1
Abstract:
The nanoparticle according to the present invention comprises a molecular aggregate containing an amphiphilic block polymer. The amphiphilic block polymer comprises a hydrophilic block chain having 20 or more sarcosine units and a hydrophobic block chain having 10 or more lactic acid units. The molecular aggregate contains a near-infrared absorbing organic molecule, which has a near-infrared absorbing functional group, at a concentration of 5 μmol/g or greater. It is preferred that the near-infrared absorbing organic molecule is a hydrophobic polymer in which the aforesaid near-infrared absorbing functional group is attached to a polymer chain having 10 or more lactic acid units. The nanoparticle according to the present invention is usable as a contrast agent for photoacoustic imaging.
