ABSTRACT
Nanoparticle synthesis using the plasma–liquid interface is especially advantageous in that toxic stabilizers and reducing agents are unnecessary and the synthesis is continuous during the plasma irradiation. This chapter discusses the synthesis of metal nanoparticles using plasma irradiation of liquid electrodes and conjugation of the metal nanoparticles with carbon nanotubes to control particle size, interparticle distance, and optical and electrical properties of the hybrid material. In particular, the boundary between plasmas and liquids, which activates physical processes and chemical reactions, has attracted much attention as a novel direction for nanobiomaterial synthesis. The formation of DNA encapsulated carbon nanotubes using a plasma ion irradiation method and controlled the electrical properties of carbon nanotubes by changing the base sequence of the encapsulated DNA. The chapter explains that nanoparticles can be conjugated with DNA and inserted into the carbon nanotubes for applications in biosensors, drug delivery system, and gene therapy.
