Background: Pseudomonas aeruginosa is the primary cause of infection with impaired defense mechanisms. P. aeruginosa commonly causes nosocomial infections and is the most common pathogen isolated from patients hospitalized for longer than 1 week. We examined the antimicrobial effect of multilayered carbon nanotubes on multi-drug-resistant. Materials and methods: In this research, 20 clinical i...

Carbon nanotubes are nanocomponents par excellence that offer unique properties to be exploited in next-generation devices. Sensing applications are perhaps the class that has most to gain from single-walled carbon nanotubes (SWNTs); virtually any property of SWNTs (e.g., electronic, electrical, mechanical, and optical) can result or has already resulted in sensor concept demonstrators. The bas...

We use electrostatic force microscopy and scanned gate microscopy to probe the conducting properties of carbon nanotubes at room temperature. Multiwalled carbon nanotubes are shown to be diffusive conductors, while metallic single-walled carbon nanotubes are ballistic conductors over micron lengths. Semiconducting single-walled carbon nanotubes are shown to have a series of large barriers to co...

We report a general strategy for synthesis of a large variety of metal oxide nanoparticles on different carbon nanomaterials (CNMs), including single-walled carbon nanotubes, multi-walled carbon nanotubes, and a few-layer graphene. The approach was based on the π-π interaction between CNMs and modified aromatic organic ligands, which acted as bridges connecting metal ions and CNMs. Our methods ...

Carbon nanotubes (CNTs) were first discovered by Iijima in 1991 [1]. CNTs have sparked great interest in many scientific fields such as physics, chemistry, and electrical engineering [2, 3]. CNTs are composed of graphene sheets rolled into closed concentric cylinders with diameter of the order of nanometers and length of micrometers. CNTs are in two kinds, based on number of walls, the single-w...

The fabrication of single-walled carbon nanotubes is still somewhat of an art form, and processes that either create the nanotubes at a much faster rate or of much greater length or purity is still needed. Zhu et al. (p. 884) use an improved floating catalyst method to create centimeterlong single-walled nanotube ropes that are significantly longer than those obtained from either chemical vapor...

in this paper, carbon nanotubes (cnts) were added into chitosan (cs) hydrogels in the form of chitosan modified cnts (cs-cnts) composites to prepare carbon nanotubes hydrogels (cnts-gel). the products, named cs-mwcnts, were characterized by scanning electron microscope (sem) and fourier transform infrared (ftir) spectroscopy. swelling properties and effect of ph on controlled release performanc...

objective(s): this paper describes a selective and sensitive biosensor based on the dissolution and aggregation of aptamer wrapped single-walled carbon nanotubes. we report on the direct detection of aptamer–cocaine interactions, namely between a dna aptamer and cocaine molecules based on near-infrared absorption at λ807. materials and methods: first a dna aptamer recognizing cocaine was non-co...

the electrochemical oxidation of sulfamethazine (smz) has been studied at a multi-walled carbon nanotubes modified glassy carbon electrode (mwcnt-gce) by cyclic voltammetry. this modified electrode (mwcnt-gce) exhibited excellent electrocatalytic behavior toward the oxidation of smz as evidenced by the enhancement of the oxidation peak current and the shift in the anodic potential to less posit...
