NOVELTY - A composition (C1) comprises a liquid, a surfactant capable of suspending carbon nanotubes, and carbon nanotubes. The liquid, surfactant and carbon nanotubes are present in a ratio suitable for the suspension of the carbon nanotubes.    USE - In generating products with improved strength, weight, strength to weight ratio, electrical and thermal versatility, radiation shielding, capacitance, dielectric properties, selective ion flow, catalytic activity and biological applications; for industrial processing of materials comprising carbon nanotubes such as fibers, films, synthetic membranes, coatings, drug delivery systems and molecular circuitry components. Also useful in any part of the process and design of fabrication of the fuel cell components such as solid oxide fuel cells and polymer electrolyte membrane fuel cell components; in fabricating storage devices such as charge storage device (supercapacitor) and electrochemical and gas phase hydrogen-storage device, batteries; as an industrial agent in molecular systems and composite systems such as reinforcements, paneling in automotive, aerospace industry, sporting goods and goods industries; in production of sensors and actuators; and in various devices such as optoelectronic and all-optical switches, lenses, probes, lasers, nano electromechanical systems, circuitry and nanoelectronics, nanomechanics (e.g. by attaching nanometers), neutral networks (nanoelectrodes for connections), nanocomputers, quantum computers, high-density magnetic memory or storage media, photonic crystals, nanocrystal antennas, multi-nanowell assay plates, nanocatalysts (e.g. palladium), nanopores for single-molecule DNA sequencing (if small length nanotubes are used), amplifiers for telecommunications (approximately 7 nm PbSe and PbS quantum dots having a tunable gap near 1500 nm), memory or storage device (e.g. hard-disk drive read heads, magnetic RAM), magnetic field sensors, magnetic logic devices, logic gates and switches.    ADVANTAGE - In the presence of the liquid and the surfactant, the interactions between the carbon nanotubes comprising the nanotube bundles, ropes or flocculants is significantly reduced, which results in the suspended, stable, non-aggregating carbon nanotubes. The use of surfactants provides highly concentrated compositions of suspended carbon nanotubes of greater than 1 wt.%. The compositions comprising the carbon nanotubes can be incorporated into bulk material and remains on the surface of the material. The coating of the nanotubes with the surfactant molecules enables the nanotubes to be dispersed in liquids such as water, and the surfactant molecules can be removed if desired after the suspended nanotubes are processed into different host systems.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a composition (C1) comprises a liquid, a surfactant capable of suspending carbon nanotubes, and carbon nanotubes. The liquid, surfactant and carbon nanotubes are present in a ratio suitable for the suspension of the carbon nanotubes to a concentration of at least 3 g/l.    (2) suspending carbon nanotubes involving combining the surfactant, the liquid and carbon nanotubes.
