Using UV Absorption Spectroscopy to Analyze ssDNA-Coated CNTs NanoLetters DNA ssDNA CNT CarbonNanotubes
By Bhavna KavetiOct 17 2022Reviewed by Susha Cheriyedath, M.Sc. Single-stranded DNA shows remarkable selectivity when coated onto single-walled carbon nanotubes. Although many previous reports have focused on the applications of these structures, very few reports have analyzed their structure and composition.
Furthermore, spectrophotometry was employed to measure the absolute concentrations of similar single-walled carbon nanotube samples in aqueous sodium dodecyl sulfate , a typical surfactant that is transparent in the mid-UV. Solute concentration plays a critical role when working with a solution or suspension. However, determining this concentration is difficult for most samples of single-walled carbon nanotubes owing to their inhomogeneous compositions. Although optical absorption measurements are inexpensive, quick, and non-destructive techniques for determining the solute concentration, knowledge of the absolute absorptivity values is required.
Moreover, adding SDS to the sample enabled the removal of ssDNA from the single-walled carbon nanotube and facilitated the measurement of pure ssDNA concentration via UV absorption spectroscopy, which resulted in an unperturbed ssDNA spectrum.
