Fabrication, Development, and Characterization of HiPco SWCNT-Alginate Hydrogel Composites for Cellular Product Applications
In this study, we designed, synthesized, and characterized ultrahigh purity single-walled carbon nanotube (SWCNT)-alginate hydrogel composites. Among the parameters of importance in the formation of an alginate-based hydrogel composite with single-walled carbon nanotubes, are their varying degrees of purity, their particulate agglomeration and their dose-dependent correlation to cell viability, all of which have an impact on the resultant composite’s efficiency and effectiveness towards biomedical applications. To promote their homogenous dispersion by preventing agglomeration of the SWCNT, at first, we used three different surfactants-sodium dodecyl sulfate (SDS-anionic), cetyltrimethylammonium bromide (CTAB-cationic), and Pluronic F108 (nonionic). After experimentation and corroboration through evidence obtained by characterization methods such as Dynamic Light Scattering, Rheology, Raman Spectroscopy, Conductivity, UV-Vis, Tensile testing and Swelling/Degradation studies with Dimensional Statistical Analysis, among others, it was determined that PF108 SWCNTs were the most stable for biomedical applications such as tissue engineering and biosensors.
