Lipase immobilized on magnetic multi-walled carbon nanotubes

Bioresource Technology, 2012
Magnetic iron oxide nanoparticles were loaded onto the surfaces of multiwalled carbon nanotubes (MWNTs) by the impregnation method. The obtained magnetic nanotubes were characterized with high-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD).

Diameter Effects on Cytotoxicity of Multi-Walled Carbon Nanotubes

Journal of Nanoscience and Nanotechnology, 2009
In this work, we focus on the diameter effects on cytotoxicity of different diametered multi-walled carbon nanotubes (MWNTs). Cellular viability, phagocytotic ability, and apoptosis of guinea pig alveolar macrophages (AM) exposed to MWNTs were studied. MWNTs in smaller diameter showed less cytotoxicity than the larger ones at the same dosage.

3D nanorobotic manipulations of multi-walled carbon nanotubes

Proceedings 2001 ICRA. IEEE International Conference on Robotics and Automation (Cat. No.01CH37164), 2002
Multi-walled carbon nanotubes (MWNTs) are manipulated in 3D space with a 10-DOF nanorobotic manipulator, which is actuated with PZTs and Picomotors/sup TM/ (New Focus Inc.) and operated inside a scanning electronic microscope (SEM). The coarse linear resolutions of the manipulator are better than 30 nm (X, Y, Z stages actuated by Picomotors) and the ...

Mechanism of Pt Loading on Multi-Walled Carbon Nanotubes

Journal of Nanoscience and Nanotechnology, 2011
Microwave treatment of multi-walled carbon nanotubes (MWCNTs) with nitric acid (HNO3) and 0.2 M sodium chlorate (NaClO3) can generate and enhance defects on the surfaces of MWCNTs. These defects are the important sites to load Pt nanoparticles (NPs). We investigated the defect induced Raman spectra and observed a decrease in the R-values (D-band/G-band

Resistance-Based Biosensor of Multi-Walled Carbon Nanotubes

Journal of Immunoassay and Immunochemistry, 2014
Multi-Walled Carbon Nanotubes (MWNTs) are a good choice for resistive biosensors due to their great resistance changes when immunoreactions take place, they are also low-cost, more biocompatible than single-walled carbon nanotubes, and resistive measurement equipment is usually not expensive and readily available.

Covalent Conjugation of Multi-walled Carbon Nanotubes with Proteins

2010
Linkage of proteins to carbon nanotubes (CNTs) is fundamentally important for applications of CNTs in medicinal and biological fields, as well as in biosensor or chemically modulated nanoelectronic devices. In this contribution, we provide a detailed protocol for the synthesis and characterization of covalent CNT-protein adducts.
