DRUG-IMMOBILIZED INORGANIC NANOPARTICLE

摘要

An object of the present invention is to provide a composite of an inorganic nanoparticle with a medicinal compound (i.e., an active substance), and to provide a method for producing the inorganic nanoparticle composite, which is highly versatile and convenient. The present invention provides an active substance-immobilized inorganic nanoparticle wherein an active substance is immobilized through physical adsorption on the surface of an inorganic nanoparticle of 1 to 500 nm in average particle size.
