  • Patent number: 11878182
    Abstract: A method of modulating neural activity using a combination of electrical and optical stimulation transmitted via a gold nanoparticle covered nanoelectrode is presented. The combination of short-duration green visible light optical pulses with the complementary sub-threshold level electric current pulses are capable of producing action potentials in neurons. Cells were found to have a greater than a 5× survival rate using this hybrid stimulation method as compared to pure plasmonic/optical stimulation. The cell stimulation success rate was 3× greater with hybrid stimulation.

  • Patent number: 11561343
    Abstract: A novel polymer optical waveguide and method of manufacturing is presented herein. A digitally manufactured process is described which utilizes a micro-dispensed UV optical adhesive as the contour guiding cladding, a fused deposition modeling technology for creating a core, and a subtractive laser process to finish the two ends of the optical interconnect. The optical waveguide can be printed directly on a circuit board in some embodiments. Alternatively, using a slightly modified process including a step to bond the optical fiber to the substrate, the optical interconnect can be manufactured on a flexible substrate.

  • Patent number: 10463878
    Abstract: A novel method to stimulate electrically active biological cells using visible wavelength light and metallic nanoparticles possessing plasmonic properties is presented herein. Using this technology, prosthetic devices such as cochlear and retinal implants and cardiac pacemakers can be developed to have superior properties as compared to the currently utilized electrical stimulation designs. These properties include improved spatial resolution; less or non-invasive devices; and higher fidelity of transduction. An additional advantage of using visible light wavelengths is the avoidance of unwanted heating of surrounding tissue that occurs with infrared stimulation.

  • Patent number: 10031140
    Abstract: Devices and methods for use in removing non-specific binding in a bioassay are disclosed. A substrate can be used with input and output transducers to output surface acoustic waves. The surface acoustic waves can be transmitted through a medium. One of the input and output transducers can be formed on the surface of the substrate aligned with an x-axis of the substrate. These input and output transducers can excite a Rayleigh surface acoustic wave through the medium. Another one of the input and output transducers can be formed orthogonal to the x-axis. These input and output transducers can excite a shear wave.
