    Abstract: The resonance contact scanning force microscope includes a reflective cantilever arm which is oscillated at a high harmonic of the resonance frequency of the cantilever arm, while the probe tip is maintained in substantially constant contact with the surface of the specimen. The motion of the free end of the cantilever arm is measured, to generate a deflection signal indicative of the amount of actual deflection of the probe tip. The method and apparatus permit high speed scans and real time imaging of the surface of a specimen with a substantial reduction in noise normally arising due to tip-surface interaction and acoustic noise.

    Abstract: Systems for analyzing multiple samples in parallel using mass spectrometric preferably coupled with fluid phase separation techniques are provided. A multi-analyzer mass spectrometer includes multiple inlets, multiple mass analyzers, and multiple transducers to conduct mass analyses of multiple samples in parallel. A modular mass analyzer may include a vacuum enclosure, a chassis, and multiple mass analysis modules disposed within the chassis. Modules are preferably disposed in a spatially compact two-dimensional array. A common multi-stage vacuum system may be utilized in conjunction with baffles or partitions disposed within and between modules to maintain differential vacuum conditions within the spectrometer utilizing a minimum number of pumps. Common control inputs may be provided to multiple modules or other components within a multi-analyzer spectrometer. Fluid phase separation devices for use with a multi-analyzer spectrometer may be microfluidic devices utilizing chromatographic, electrophoretic, or other separation methods.

    Abstract: The scanning force microscope is an improved free standing type scanning force microscope with integrated scanning drivers for examination of a wide range of sizes and weights of stationary specimens, with the capability of scanning a sample in contact with a fluid. The scanning force microscope also includes motorized driver legs for operating the approach of the optical lever arm and sensor head to the sample, to allow for automation of the approach of the sensor head to the specimen.

    Abstract: An agent for contrast enhancement in nuclear magnetic resonance imaging is disclosed. Micellular particles such as phospholipid vesicles are associated with or enclose a paramagnetic material. The particles may be formulated with an agent, such as cholestrol, to promote vesicle stability and water exchange across the vesicle bilayer. The vesicles may or may not have antibodies or other cell recognition targeting agents attached to the surface to provide specific targeting. The vesicles provide enhanced target specificity, reduced burden of toxic contrast material and amplified contrast enhancement.
