Abstract: A method of extracting neural stem cells from a living subject, comprising the steps of introducing magnetic nanoparticles into the subject, targeting the neural stem cells with the magnetic nanoparticles to form magnetic nanoparticle-targeted cells, isolating the magnetic nanoparticle-targeted cells, extracting the magnetic nanoparticles-targeted cells from the subject.

Abstract: A lip-based speaker verification system for identifying a speaker using a modality of lip motions; wherein an identification key of the speaker comprising one or more passwords; wherein the one or more passwords are embedded into lip motions of the speaker; wherein the speaker is verified by underlying dynamic characteristics of the lip motions; and wherein the speaker is required to match the one or more passwords embedded in the lip motions with registered information in a database. That is, in the case where the target speaker saying the wrong password or even in the case where an impostor knowing and saying the correct password, the nonconformities will be detected and the authentications/accesses will be denied.

Abstract: A novel multilayer flexible metamaterial that can work at near infrared (NIR) regime that can be fabricated on transparent PET substrate using flip chip transfer (FCT) technique. An embodiment of the present invention also provides novel NIR metamaterial device that can be transformed into various shapes by bending the PET substrate, wherein said metamaterial device is tunable via physical manipulation of its flexible substrate with no requirement to change the material composition of the substrate. The flexibility allows the novel NIR metamaterial device to bend and stretch, which can alter the device structure. Since the resonant frequency of each device is a function of the device structure, the resonant frequency can be tuned by the bend and stretch of the substrate. Another embodiment of the present invention further provides novel tunable sensors and emitters using such flexible metamaterials and devices.

Abstract: A method and apparatus of fabrication of a multilayer flexible metamaterial can be fabricated using flip chip transfer (FCT) technique. This technique is different from other similar techniques such as metal lift off process, which fabricates the nanostructures directly onto the flexible substrate or nanometer printing technique. It is a solution-free FCT technique using double-side optical adhesive as the intermediate transfer layer and a tri-layer metamaterial nanostructures on a rigid substrate can be transferred onto adhesive first. Another embodiment of the present invention is the fabrication method and apparatus that allows the transfer of the metamaterial from a rigid substrate such as glass, quartz and metals onto a flexible substrate such as plastic or polymer film. Thus, a flexible metamaterial can be fabricated independent of the original substrate used.
