Hybrid Carbon

This report deals with a simple and efficient method to develop hybrid carbon nanoparticles (Nps) employing Multi-walled carbon nanotubes (MWCNTs) and Fullerene nps. Fullerene nps were self-assembled via Ultrasonicated Liquid-Liquid Precipitation. Surface treated MWCNTs were entangled with fullerene nps during the process of assembling of the fullerene nps. Fullerene nps are formed by reaction between two solutions, one is the saturated solution which contains dissolved fullerene and other solution is a rough alcohol. This reaction increases the concentration of carbon in the solution and leads to super saturate hence self-assembling into nanoparticles. The obtained hybrid nanoparticles sizes were in the range of 100 nm to 300 nm with entangled mwcnts and were confirmed by characterization using SEM, Raman, UV-Vis, XRD, and DLS.

ABSTRACTGram positive (Lactoccocus lactis) and Gram negative bacteria (Escherichia coli) were used to study the interaction of water-dispersible muti-walled carbon nanotubes (CNTs) with the bacterial cell envelope during microwave (MW) energy exposure. It was observed that the addition of a tiny amount of CNTs to a medium containing bacteria and subsequent exposure of the samples to MW, leads to an intimate contact between the CNT tips and the cell envelope. This phenomenon can be explained in terms of attractive forces between opposite charges of polar structures. Since CNTs under MW irradiation behave like electric dipoles, this would make it possible for the CNTs to target the cell surface without inducing changes in the cell shape and viability. Thus, the electrochemical properties of CNTs and their capillarity make them useful tools for cell manipulation, and therefore for the intracellular transport of drugs, dyes or biomolecules.
