  • Patent number: 11320303
    Abstract: Embodiments relate to a sensor structure for an acoustical pressure sensor and an opto-mechanical sensor and system that may be used for detecting acoustical pressure waves. Embodiments of a sensor structure for an acoustical pressure sensor include an optical waveguide closed-loop resonator and a plurality of sensor elements. The individual sensor elements of the plurality of sensor elements are configured to be affected by an acoustical pressure wave such that a physical property of the individual sensor element is changed. The optical waveguide closed-loop resonator is arranged at the plurality of sensor elements and associated with each of the individual sensor elements such that a resonance frequency of the optical waveguide closed-loop resonator is shifted due to the affected physical properties of all individual sensor elements. The sensor structure provides a high sensitivity from each sensor element, which is advantageous in e.g.

  • Publication number: 20220091096
    Abstract: A method for detecting an analyte in a sample includes the steps of obtaining a nanopore sensor comprising a nanopore and a protein adaptor internalized in the lumen of the nanopore, adding a sample comprising an analyte to the cis side or the trans side of the nanopore, and measuring conductance across the nanopore. A change in conductance after adding the sample indicates the analyte is present in the sample and has bound to the protein adaptor. Nanopore sensors comprise a nanopore and a protein adaptor internalized in the lumen of the nanopore. The protein adaptor is a functional enzyme or ligand-binding protein.

  • Patent number: 11278859
    Abstract: A miniaturized, automated method for controlled printing of large arrays of nano- to femtoliter droplets by actively transporting mother droplets over hydrophilic-in-hydrophobic (“HIH”) micropatches. The technology uses single or double-plate devices where mother droplets can be actuated and HIH micropatches on one or both plates of the device where the droplets are printed. Due to the selective wettability of the hydrophilic micropatches in a hydrophobic matrix, large nano- to femtoliter droplet arrays are created when mother droplets are transported over the arrays. The parent droplets are moved by various droplet actuation principles. Also, a method using two plates placed one top another while being separated by a spacer. One plate is dedicated to confirming and guiding parent droplets by using hydrophilic patches in a hydrophobic matrix, while the other plate contains HIH arrays for printing of the droplets.

  • Patent number: RE48856
    Abstract: The application relates to the field of cancer, particularly to the field of solid tumors. It was found that a particular long non-coding RNA (lncRNA), NEAT1, an essential architectural component of nuclear paraspeckles, is required for the survival of cancer, but not that of normal, non-transformed, cells. Inhibition of NEAT1 reduces cell viability of cancer cells and induces apoptosis. These data identify NEAT1 as a novel therapeutic target for treatment of solid tumors.
