  • Patent number: 8969827
    Abstract: A specimen kit having a tiny chamber is disclosed for a specimen preparation for TEM. The space height of the chamber is far smaller than dimensions of blood cells and therefore is adapted to sort nanoparticles from the blood cells. The specimen prepared under this invention is suitable for TEM observation over a true distribution status of nanoparticles in blood. The extremely tiny space height in Z direction eliminates the possibility of aggregation of the nanoparticles and/or agglomeration in Z direction during drying; therefore, a specimen prepared under this invention is suitable for TEM observation over the dispersion and/or agglomeration of nanoparticles in a blood.

    Abstract: A method and apparatus for nanoscopy comprising a salt microlens. The microlens-based nanoscope comprises a conventional microscope, a microlens, and a XYZ piezoelectric stage is shown (SEE FIG. 1A). The microlens is mounted on a Z-stage and can be driven to accomplish the scanning. The specimen is placed above the microlens which is a plano-convex lens. The set up employed for the Salt Microlens for Ultra-high Resolution Imaging (SAMURI) can use a halogen-tungsten lamp with a dominant wavelength at 600 nm. A magnified virtual image of the specimen is obtained when the distance between microlens and specimen is less than the focal length of the microlens. The virtual image can then be magnified by the microscope and captured by eyes or a CCD camera.

  • Patent number: 8704155
    Abstract: Detection of individual objects using a light source and a whispering gallery mode (WGM) resonator. Light from the whispering gallery mode (WGM) resonator is analyzed. The presence of an object is determined based on mode splitting associated with the light received by the photodetector. For example, the presence of the object may be determined based on the distance between two whispering gallery modes and/or the linewidths of the two modes in a transmission spectrum. Alternatively, the presence of the object may be determined based on a beat frequency that is determined based on a heterodyne beat signal produced by combining split laser modes in the received light from a WGM microcavity laser.

    Abstract: A method for producing planar extended electrodes with nanoscale spacings that exhibit very large SERS signals, with each nanoscale gap having one well-defined hot spot. The resulting highly sensitive substrate has extended metal electrodes separated by a nanoscale gap. The electrodes act as optical antennas to enhance dramatically the local electromagnetic field for purposes of spectroscopy or nonlinear optics. SERS response is consistent with a very small number of molecules in the hotspot, showing blinking and wandering of Raman lines. Sensitivity is sufficiently high that SERS from physisorbed atmospheric contaminants may be detected after minutes of exposure to ambient conditions.

  • Patent number: 8184298
    Abstract: Methods and apparatus for rendering quantitative phase maps across and through transparent samples. A broadband source is employed in conjunction with an objective, Fourier optics, and a programmable two-dimensional phase modulator to obtain amplitude and phase information in an image plane. Methods, referred to as Fourier transform light scattering (FTLS), measure the angular scattering spectrum of the sample. FTLS combines optical microscopy and light scattering for studying inhomogeneous and dynamic media. FTLS relies on quantifying the optical phase and amplitude associated with a coherent image field and propagating it numerically to the scattering plane. Full angular information, limited only by the microscope objective, is obtained from extremely weak scatterers, such as a single micron-sized particle. A flow cytometer may employ FTLS sorting.

One method includes generating positional information about a location on a surface of a specimen with an optical subsystem. The method also includes positioning an atomic force microscopy probe proximate the location based on the positional information. Another system includes an optical subsystem configured to measure overlay of a wafer using scatterometry. The system also includes an atomic force microscope configured to measure a characteristic of a feature on the wafer. An additional method includes measuring overlay of a wafer using scatterometry. The method also includes measuring a characteristic of a feature on the wafer using atomic force microscopy.

  • Publication number: 20080154521
    Abstract: A scanning probe microscope's probe tip dimensions as they exist or existed for a certain data or measurement are inferred based on probe activity taking place since a probe characterization procedure was performed. The inferred probe tip dimensions can be used to correct nanoscale measurements taken by the probe to account for changes in the probe's geometry such as wear.

  • Patent number: 7315374
    Abstract: An embodiment of the present invention is a technique to monitor carbon nanotubes (CNTs). A carbon nanotube (CNT) is manipulated in a fluid by a laser beam. An illuminating light from a light source is aligned along axis of the CNT to produce an optical response from the CNT. The CNT is monitored using an optical sensor according to the optical response.

  • Patent number: 7268269
    Abstract: A reactive and adsorptive (i.e., multi-functional protective) textile and methods for constructing and using same which possess at least chemically reactive and biocidal properties. Nanoparticles from different classes such as metal oxides, metal hydroxides, metal hydrates and POMs are incorporated into elements which can be utilized in a wide variety of protective materials. The nanoparticles may be treated to reduce water solubility or combined with halogens, alkali metals or secondary metal oxides to specifically engineer the nanoparticle to address a particular chemical or biocidal threat.
