  • Patent number: 11099004
    Abstract: A method of marking a hydrated tissue specimen for mechanical testing is provided. The method includes adding a metal nanoparticle precursor solution to a reducing agent solution to form a mixture; incubating the mixture to form a plurality of aggregated metal nanoparticles, where each of the aggregated metal nanoparticles includes a plurality of individual metal nanoparticles; separating the plurality of aggregated metal nanoparticles from a supernatant by means of centrifugation or gravitational settling; resuspending the plurality of aggregated metal nanoparticles in a buffer solution to form a colloidal metal nanoparticle suspension; and soaking the hydrated tissue specimen in the colloidal metal nanoparticle suspension, where at least a portion of the plurality of aggregated metal nanoparticles adhere to the hydrated tissue specimen in a random pattern of speckles.
    Type: Grant

  • Publication number: 20150089394
    Abstract: A technology for interacting with a collaborative videoconferencing environment is disclosed. A display having a substantially “L-shaped” configuration allows for display of collaborative materials and video of remote participants simultaneously, which provides for a more natural interaction for a meeting participant interacting with the collaborative materials. Meeting participants can electronically retrieve or send materials to the collaborative meeting via interactions with their personal computing devices.
