Keywords:atmospheric-pressure microplasma, Au nanoparticles, SWNTs

The research for the gold nanoparticle (AuNPs) biosensor has been conducted because of their high catalytic activity. The authors have successfully synthesized AuNPs with the diameters of 2-10 nm by irradiating an atmospheric-pressure He microplasma (AP-HeμP) to the HAuCl₄ solution with the volume of 170 μL. In this study, we try to synthesize AuNPs@CNT by irradiating the AP-HeμP to a small amount of a mixed solution comprising HAuCl₄, catechin and SWNTs.
