In the present study, we have carried out the study to understand the interaction between the plasma and nanostructured materials. The main research subjects are to fabricate nano-sized particles by using dc arc discharge, to modify their surfaces of nanoparticles or nano-structured materials by using plasma chemical modification, and to immobilizethe biomolecules onto the surface of nanoparticles for bio- and medical application. Immobilization of the antibody of influenza virus onto the surface of aminated magnetic nanoparticles has been carried out for aiming at developing the feasibility of the selective detection of virus. The significant enhancement of condensation rate of influenza A type virus was confirmed by magnetic collection of antibody-immobilized magnetic nanoparticles. The result suggests a feasibility of the present method for selective influenza virus detection.
