  • Publication number: 20220003798
    Abstract: A method comprises using an atomic-force microscope, acquiring a set of images associated with surfaces, and, using a machine-learning algorithm applied to the images, classifying the surfaces. As a particular example, the classification can be done in a way that relies on surface parameters derived from the images rather than using the images directly.

  • Patent number: 11099210
    Abstract: A method of carrying out sub-resonant tapping in an atomic force microscope includes causing a probe that is disposed above a sample to be translated in a direction parallel to a horizontal plane defined by the sample and to oscillate in a vertical direction that is perpendicular to the horizontal plane about an equilibrium line that is separated from the horizontal plane by a vertical offset. As a result, the probe repeatedly taps a surface of the sample. Each tap begins with a first contact of the probe on the surface followed by a progressive increase in force exerted by the sample on the probe until a peak force is attained. The vertical offset is controlled by relying at least in part on a feature other than the peak force as a basis for controlling the vertical offset.

  • Publication number: 20200114329
    Abstract: This application discloses the approach of synthesizing cellulose acetate nanoparticles and rods which may have a chemically functionalized surface and an encapsulated cargo load. Functionalization and/or loading of the cargo are made through a physical mixing of the functionalizing and/or cargo components in the synthesizing bath. This can result in particles with functionalized surfaces with various functional groups, as well as active cargo load encapsulated in the particles. The encapsulated cargo includes but is not limited to biologically, chemically, and optically active substances.

  • Patent number: 9701900
    Abstract: Ultrabright fluorescent silica particles that can take stable temperature measurements, and methods of their manufacture. The particles have encapsulated fluorescent substances, some of which can exhibit altering fluorescent characteristics depending on temperature. The particles function as a thermometer allowing one to measure the temperature of the environment. A ratio of the fluorescent peaks in the fluorescent spectrum of each particle depends on temperature, but is dependent on neither the amount of exciting light nor the size of the particles. Further, the particle size can be confined to the range of 8 nm to 100 ?m.

  • Patent number: 9676620
    Abstract: The invention generally relates to fluorescent particles and more specifically to silica-based fluorescent nanoporous particles with physically encapsulated organic dyes. In one aspect of the invention, the nanoporous architecture provides a significant enhancement in fluorescence of the particles brightness compared to free dye. A particular chemical control of the silica matrix prevents the dye molecules from leaking the particles.
