Title: Separation of Metallic Single-walled Carbon Nanotubes and Semiconducting Single-walled Carbon Nanotubes by Agarose Gel Electrophoresis
Abstract: The agarose gel electrophoresis(AGE) is one of the low-cost,large scale technologies for the separation of metallic single-walled carbon nanotubes(m-SWCNTs) and semiconducting single-walled carbon nanotubes(s-SWCNTs).The separated m-SWCNTs are divided into several parts and characterized by the UV-visible-near infrared absorption spectrum and the Raman spectrum respectively.The results show that the moieties with the fastest electrophoresis migration rate contain more m-SWCNTs.Furthermore,the effects of different agarose concentrations on the separating efficiencies of SWCNTs are investigated.It is found that higher concentration of agarose gel is beneficial to the enrichment of the m-SWCNTs and the separating efficiency of the m-SWCNTs could be realized by increasing the charge density on the surface of the SWCNTs.
