Special Issue Information

Dear Colleagues,

Carbon nanomaterials (CNMs) such as graphene, graphene oxide, carbon nanotubes, and nanofibers possess excellent chemical, physical, and biological properties, which render them very promising for a wide range of bioengineering applications: tissue engineering, drug/gene delivery, anticancer therapy, stem cell differentiation, agriculture engineering, photodynamic therapy, biosensors, etc. Furthermore, carbon nanotechnology has emerged as an alternative promising antimicrobial strategy against clinically relevant multidrug-resistant pathogens. Thus, most recent studies have demonstrated high antimicrobial activity and noncytotoxicity of CNMs. In this regard, CNMs in pure form, functionalized or in combination with other materials such as polymers can be exploited to produce a broad range of advanced nano- and macrobiomaterials with enhanced properties in terms of mechanical, electrical, and thermal performance, water sorption/diffusion, wettability, antimicrobial activity, and cell adhesion and proliferation.

In this context, we invite authors to submit original research articles, communications and reviews for this Special Issue of C—Journal of Carbon Research, “Carbon Nanomaterials and Nanocomposites in Bioengineering & Chemical Engineering”, which is focused on all the advances in this research field.

It has been reported that even if single-walled carbon nanotubes (SWNTs) are coated with the same polymer, the redox characteristics change of each chirality may differ. Particularly, the addition of hydrogen peroxide (H2O2) minimally affects the near-infrared (NIR) absorption spectra of the dsDNA-(6,5)-enriched SWNT complex (DNA-SWNT complex). Detecting the redox properties of (6,5) chirality using NIR absorption spectra has been one of the issues to be solved. We hypothesized that an oxidizing agent with high oxidizing power is required to detect the absorption spectra of (6,5) chirality. In this study, we used KMnO4, which contains atoms with a high oxidation number. A dispersion was prepared by mixing 0.5 mg of (6,5)-enriched SWNT powder with 1 mg/mL of DNA solution. After adding H2O2 or KMnO4 to this dispersion and oxidizing it, catechin solutions were added to reduce the dispersion. The absorption peak of the DNA-SWNT complex decreased by 23.9% following the addition of KMnO4 (final concentration: 0.5 µM) and recovered 30.7% following the addition of the catechin solution. We revealed that the changes in the absorption spectra change of (6,5) chirality, which could not be detected by H2O2, can be detected by using KMnO4. We also varied the concentration of KMnO4 and verified whether the adsorption of KMnO4 can be modeled as a Langmuir adsorption isotherm. Full article
