・Biocompatibility Improvement:Organic/Inorganic Coating

In case of using nanoparticles in the biomedical field, it is widely studied to modify the surface of the nanoparticles with organic or inorganic materials, for instance, to prevent nonselective protein adhesion. Our research group tried coating various nanoparticles with polyethylene glycol (PEG) or silica (SiO₂) and evaluated its optical properties and stabilities.
