Abstract Pristine carbon nanotubes (CNTs) and functionalized (f-CNTs) were introduced into conductive poly(methyl methacrylate)/graphene nanoplatelet (PMMA/GNP) composites to achieve a synergistic effect in the enhancement of conductivity reduction percolation threshold by forming 3-Dimensional(3-D) hybrid structure. Both in-plane perpendicular electrical properties investigated. The synergies ...

In this study, the vanadium pentoxide (V2O5), functionalized carbon nanotubes (f-CNT), and polypyrrole (PPy) based composites films have been prepared through a facile synthesis method their electrochemical performance were evaluated as freestanding negative electrodes of supercapacitor. A hydrous V2O5 gel by treating powder with H2O2 was mixed f-CNT to obtain V2O5/f-CNT composite film. then co...

In spite of significant insolubility and toxicity, carbon nanotubes (CNTs) erupt into the biomedical research, and create an increasing interest in the field of nanomedicine. Single-walled CNTs (SWCNTs) are highly hydrophobic and have been shown to be toxic while systemically administrated. Thus, SWCNTs have to be functionalized to render water solubility and biocompatibility. Herein, we introd...

In this report, a new cholesterol sensor is developed based on a vertically aligned CNT electrode with two-step electrochemical polymerized enzyme immobilization. Vertically aligned CNTs are selectively grown on a 1 mm(2) window of gold coated SiO(2)/Si substrate by thermal chemical vapor deposition (CVD) with gravity effect and water-assisted etching. CNTs are then simultaneously functionalize...

Hydrothermally and sol-gel-synthesized immobilized surfactant-modified polyaniline-carbon nanotubes/TiO₂ (PANi-CNT/TiO₂) photocatalysts were prepared and their application in the degradation of diethyl phthalate (DEP) under visible light at 410 nm was investigated in this sturdy. To improve the dispersion of nanoparticles and the transfer of electrons, the TiO₂ surface was modified with both so...

Sensor coverage will benefit from finding better ways to communicate among smaller sensors. Also, as development in nanotechnology progresses, the need for low-cost, robust, reliable communication among nano-machines will become apparent. Communication and signaling within newly engineered inorganic and biological nano-systems will allow for extremely dense and efficient distributed operation. ...

The preparation of carbon nanotube (CNT)/PdO nanoparticles and graphene oxide (GO)/PdO nanoparticle hybrids via a general aqueous solution strategy is reported. The PdO nanoparticles are generated in situ on the CNTs and GO by a one-step "green" synthetic approach in aqueous Pd(NO(3))(2) solution under ambient conditions without adding any additional chemicals. The production of PdO is confirme...

The effects of oxygen reactive ion etching (RIE) on the surface wettability of aligned carbon nanotube (CNT) films have been systematically investigated. It was found that 3 s of RIE treatment could change the surface of CNT films from hydrophobic to more hydrophilic. The degree of modification in the surface wettability of the film could be controlled by the flow rate of O2 gas during the RIE ...

Carbon nanotubes (CNTs) are nanomaterials with interesting emerging applications. Their properties make CNTs excellent candidates for use as new nanovehicles in drug delivery, immunization and diagnostics. In the current study, we assessed the immune-response-amplifying properties of CNTs to haptens by using azoxystrobin, the first developed strobilurin fungicide, as a model analyte. An azoxyst...

Carbon nanotubes (CNTs) have shown great potential in both photothermal therapy and drug delivery. In this study, a CNT derivative, hyaluronic acid-derivatized CNTs (HA-CNTs) with high aqueous solubility, neutral pH, and tumor-targeting activity, were synthesized and characterized, and then a new photodynamic therapy agent, hematoporphyrin monomethyl ether (HMME), was adsorbed onto the function...
