Abstract: A Nanomotion Sensor comprises a micromechanical device for the detection and characterization of specimen motions when they interact with one or an array of cantilevered sensors set in the path of the moving specimen. In particular, the present invention provides a method for direct sensing and characterization of motion, including position, torsion, magnitude and direction of velocity, acceleration, force, torque, as well as binding, which may include hydrogen bonding, electrostatic attractions, hydrophobic effects, dipole interactions, or through other forces through the deflection of a micromechanical cantilever sensor. The present invention is particularly useful for the detection and characterization of the motion of biological cells such as bacteria and sperm, biological systems including motor proteins, cilia of the hearing organ and the lining of the airways in asthmatics, and microfabricated systems.

Abstract: A device for producing patterns includes a heater heating a thermal conductivity mask that has at least one cavity, and a thin film positioned adjacent to the mask. The heater may be any convenient heat source. In a preferred embodiment, the thermal conductivity mask is a plate having a pattern of cavities, holes or openings, and the thin film is held in tension over the mask. The cavities, holes or openings in the mask reduce the rate of heat flow because they contain material having lower thermal conductivity than the material of the mask. Thus the thermal conductivity mask can produce a pattern by selectively conducting heat, because properties or characteristics, such as the color, of a sample placed on the thin film can change with exposure to heat. The thermal conductivity mask achieves high print or pattern quality by utilizing the large difference between thermal conductivities of the cavity, typically air, and the mask, typically a metal.
