Optical pH Response of DNA Wrapped HiPco Carbon …

Here we have observed that HiPco nanotubes can be stably dispersed into double-stranded DNA aqueous solutions. Interestingly, the first optical interband transitions of the DNA wrapped semiconducting HiPco nanotubes possess a unique pH dependence, a phenomenon observed in SDS-encased and carboxylic group functionalized single-walled carbon ...

Optical Absorption Spectroscopy of DNA-Wrapped …

Optical absorption spectroscopy provides evidence for individually dispersed carbon nanotubes. A common method to disperse SWCNTs into aqueous solution is to sonicate the mixture in the presence of a double-stranded DNA (dsDNA). In this paper, optical characterization of dsDNA-wrapped HiPco carbon nanotubes (dsDNA-SWCNT) was carried out using near infrared (NIR) spectroscopy and ...

An Efficient Method to Completely Remove Catalyst ...

An efficient, economic and easy method for removing 99% of catalyst particle from high pressure carbon monoxide (HiPCO) single walled carbon nanotubes (SWCNT) is reported. The experiment is carried out at low temperature followed by acid treatment. The process exploited here is oxidation of the carbon impurities to gaseous phase as CO2 and removal of oxidized catalyst debris using acid treatment.

New Way to Make Carbon Nanotubes Compares Well …

Moreover, over the years, nanotubes made through the HiPco method have been very well-studied, reducing the number of challenges associated with their incorporation into numerous applications. While there are multiple ways to produce nanotubes, there are only two types of nanotubes themselves: single-walled and multi-walled.
