Magnetic Resonance

Carbon Nano Tubes (CNTs) have excellent electrical and mechanical properties. Their Young’s modulus is about 1 TPa, and the tensile strength reaches about 11-63 GPa. These extraordinary properties make them very attractive for advanced mechanical applications. At microscopic scale, CNTs have promised bright future for Nano Electro Mechanical Systems (NEMS) through the successful demonstrations on high frequency oscillators, rotational actuators, nanometer tweezers and nanometer cargoes. These NEMS devices possess unique motion capabilities that are useful for a range of sensing and detection applications. The ultraminiature sensors could provide spatial resolution at the atomic scale and vibrate at frequencies in the gigahertz range, making them possible to measure the forces between individual biomolecules, forces arising from magnetic resonance of single spin, and perturbations that arise from mass fluctuations involving single atoms and molecules.
