DEVELOPMENT OF ARC DISCHARGE METHOD IN ORGANIC SOLVENTS FOR THE FORMATION OF DNA ENCAPSULATED CARBON NANOTUBES

摘要

A simplified arc discharge plasma method in DNA dispersed organic solvents is developed for the formation of DNA encapsulated nanocarbons. The arc discharge is performed using graphite electrodes in a DNA/distilled water and DNA/methanol solution, and as a result, the soot is obtained in the solution containing multi-walled carbon nanotubes and onion-like nanocarbons. In the case that the arc discharge is performed in a DNA/toluene solution, the soot is obtained at the electrode tip and the contained nanomaterials have spheroidal shapes. Therefore this arc discharge method in the DNA dispersed solution has a possibility of the formation of the encapsulation of DNA into their structure.
