Nanomaterials are the foundations of Nanotechnology, which measured in nanoscales, Carbon nanotubes one interesting nanomaterials, studied for over 25 years because their superlative properties such as high surface area, electrical and thermal conductivity, biocompatibility, flexibility, resistance to corrosion nanosize. According research, carbon applied sensing, water treatment, drug delivery...

Background: Drugs, especially antibiotics, are one of the serious problems of modern life and the main pollution sources of the environment, especially in the last decade, which are harmful to human health and environment. The aim of this study was to investigate the removal of penicillin G from aqueous solutions using single-walled and multi-walled carbon nanotubes. Methods: In this study, t...

Local chemical functionalization of single-walled carbon nanotubes (SWCNTs) has been developed as a means defect doping to enhance the near infrared photoluminescence properties materials. Wavelength-tunable and exciton trapping-induced bright emission appears from locally functionalized SWCNTs (lf-SWCNTs). Molecularly designed lf-SWCNTs based on our approach produce new dynamic switching funct...

Single walled carbon nanotubes were functionalized with different functionalities by simple dip coating. This fast and reproducible procedure was realized with nanotube coated electrodes for the construction of polyvalent biosensors. Three different pyrene derivatives were attached to the nanotube sidewalls by π-stacking interactions in a one-step reaction.

Protein nanofibrils offer advantages over other nanostructures due to the ease in their self-assembly and the versatility of surface chemistry available. Yet, an efficient and general methodology for their post-assembly functionalization remains a significant challenge. We introduce a generic approach, based on biotinylation and thiolation, for the multi-functionalization of protein nanofibrils...

The use of the biocompatible amphiphilic diblock copolymer poly(ethylene glycol-b-propylene sulfide) (PEG44PPS20) allows a tuned loading of doxorubicin onto the surface of non-functionalized multi-walled carbon nanotubes and an efficient cell internalization. The obtained multi-walled carbon nanotube-based systems show enhanced cytotoxic activity with respect to non-vehicled doxorubicin.

Carbon nanotubes display either metallic or semiconducting properties. Both large, multiwalled nanotubes (MWNTs), with many concentric carbon shells, and bundles or "ropes" of aligned single-walled nanotubes (SWNTs), are complex composite conductors that incorporate many weakly coupled nanotubes that each have a different electronic structure. Here we demonstrate a simple and reliable method fo...

The nanotribological characterization of carbon nanotubes is fundamental for the exploration of new sliding applications. In this study, a comprehensive investigation of adhesion, friction and wear of a multiwalled nanotube (MWNT) tip, and SWNT (single-walled nanotube) and MWNT arrays has been carried out. A nonlinear response of the MWNT tip is observed when the tip is brought into and out of ...

We introduce intertube interactions of a cantilevered triple-walled carbon-nanotube (TWCNT) resonators via classical molecular dynamics simulations. The fundamental frequencies of TWCNT resonators were less than those of singleand double-walled carbon nanotubes of a given diameter because of the increasing intertube disturbance. Our results imply that for a nanotube with a given diameter, the f...
