“…This may be caused by changing the hydrogen bonds between the bases of natural DNA molecule under DNA/SWNTs interaction, resulting in the unwrapping of the DNA double helix and the exposure of the primary redox sites of adenine and guanine residues in natural DNA. This is consistent with the result of DNA/ SWNTs interaction studied by IR and UV spectroscopy [31,32]. Similar results of natural calf thymus DNA was also obtained at the SWNT-modified electrode.…”

Single-wall carbon nanotubes (SWNTs) can be used as an electrochemical probe to study the electrochemical oxidation of DNA, two voltammetric oxidation peaks corresponding to electrochemical oxidation of guanine and adenine residues in DNA could be observed, demonstrating a new potential application of SWNTs in DNA analysis. Compared to other types of electrode materials, the electrochemical response of natural DNA was greatly enhanced at the SWNT-modified electrode. This method can be used to investigate the interaction of SWNTs with DNA.

“…UV and IR spectroscopy have both been used to show that non-f -SWNTs and double-stranded DNA interact through hydrogen bonds [224,225]. Changes in the electronic levels in the nucleotide bases of the DNA molecule were found in these studies and the DNA acquired a chaotic sphere conformation upon interaction with CNTs.…”

“…In Figure 1c, the peak absorption observed around 275 nm is for the layer of wrapped DNA, which is due to the variation of the bonds between the bases of guanine-adenine under the partial unfolding of the DNA double spiral in the SWCNT-AgNPs/DNA NCs. [30] The dispersion of SWCNT-AgNPs in the PVA solution show relatively well resolved Van Hove transition absorption peaks (Figure 1e). In all the NCs, the surfactant plays an important role that the hydrophobic tails of SDS surrounds the individual conjugates and prevents their tendency to re-aggregation.…”

We report a comprehensive study of fabrication of advanced CNT-AgNPs/Polymer based nanocomposites (NCs) including structural (UV-Vis, FT-Raman, EDS, and XRD), morphological (FE-SEM, AFM, and TEM), thermal (TGA and DSC), and preliminary antimicrobial properties. Electrostatic attraction was utilized to incorporate silver nanoparticles (AgNPs) on carboxylic group functionalized single walled carbon nanotubes (SWCNTs). This was achieved by in-situ reduction of AgNO 3 and immobilization of AgNPs using NaBH 4 (reductant) under ultrasonication. As fabricated, AgNPs-SWCNTs were then reacted separately with various kinds of polymers such as DNA (bio-polymer), methacryl polyhedral oligomeric silsesquioxane (MA-POSS inorganic elastomer), and poly vinyl alcohol (PVA organic polymer) in presence of anionic surfactant sodium dodecyl sulfate (SDS). Obtained results ensure the successful incorporation of AgNPs and hybridization of different polymers on SWCNTs, respectively. Reaction mechanism involved between the SWCNTs, AgNPs, and polymers were significantly explained. Fundamental antimicrobial screening of NCs meets the requirement of biomedical application. Further, the resulted nanocomposites might have a promising role in reinforcement, coating, nanofillers, and as substrate additives for multiple studies.
