Organic-inorganic composite nanoparticles for diagnosis and therapy, and producing the same

摘要

The present invention relates to an inorganic material operating as a contrast medium for magnetic resonance images (MRI) and an organic polymer composite nanoparticle capable of light and heat treatment. The contrast medium for MRI and a light and heat treatment agent using the nanoparticle of the present invention can diagnose diseases using MRI and generate local heat by emitting low energy. Therefore the present invention can be applied to a noninvasive concentrated treatment to a part after the early diagnosis of cancer. [Reference numerals] (AA) Polymer for the dispersion on the water; (BB) Polyaniline nanoparticle dispersed on the water through surface modification (before doping); (CC) Inorganic nanoparticle capable of acting as a contrast medium; (DD) Organic/Inorganic composite polyaniline nanoparticle (after doping)
