Biomedical studies of single -walled carbon nanotubes using near-infrared fluorescence
… providing a scientific foundation for the use of single-walled carbon nanotubes (SWNTs) in biomedical applications. SWNTs have been found to be a unique class of nanoscale near-infrared (NIR) fluorescence contrast agents that also exhibit novel therapeutic capabilities. In our first study, we …

Gas phase production of single-walled carbon nanotubes
Single-walled carbon nanotubes have been produced in a continuous flow gasphase catalytic growth process, in a heated flow of carbon monoxide at pressures of 1--10 atmospheres and temperatures of 800--1200°C. Catalytic cluster nuclei for the nanotubes are generated in situ by thermal …

Theoretical and simulation tools for electron transfer and chain reactions in single walled carbon nanotubes
Single walled carbon nanotubes (SWNT) are cylindrical sheets of graphene whose electronic structures and diameters are determined by their chiralities. Current synthetic methods produce batches of nanotubes containing a variety of electronic properties. The separation of these mixtures into …

Biopolymer-mediated analyte detection via photoluminescence modulation of single-walled carbon nanotubes
Single-walled carbon nanotubes (SWNT) have unique photo-physical properties which, through the work in this dissertation, are investigated and harnessed to produce optical sensors with unique capabilities. Early studies of the modulation of SWNT optical properties—both photoluminescence and …

Electronic detection of molecules on the exterior and molecular transport through the interior of single walled carbon nanotubes
Single walled carbon nanotubes (SWNT) are unique materials with high surface to volume ratio and all atoms residing on the surface. Due to their tubular shape both exterior and interior of the SWNT are available for interaction with other molecules. One-dimensional electronic structure of SWNT is …

Charging and defects in single-walled carbon nanotubes
Single-Walled Carbon Nanotubes (SWCNTs) have been one of the most intensively studied materials. Because of their single-atomic-layer structure, SWCNTs are extremely sensitive to environmental interactions, in which charge transfer and defect formation are the most notable effects. Among a number …

Gas chromatography on self assembled single walled carbon nanotubes
Carbon nanotubes (CNTs) are nano-sized carbon-based sorbents, which have high surface area, large aspect ratio, can be self-assembled and are known to be stable at high temperatures. It is therefore conceivable that separation techniques, such as, gas chromatography (GC) can benefit from their …
