  • Patent number: 11820970
    Abstract: The present invention relates to methods and compositions for the high throughput screening of protein-protein interactions in yeast liquid culture. Protein fusions non-native to yeast may be expressed to replace endogenous sexual agglutination proteins and mediate library-by-library interrogation of protein interactions. The methods and compositions of the invention can be utilized for the characterization of protein interaction networks in high throughput for both binding affinity and specificity, which is crucial for understanding cellular functions, screening therapeutic candidates, and evaluating engineered protein networks.

  • Publication number: 20230363654
    Abstract: Examples of systems and methods are described for detecting heart beats of a subject. The systems and methods may be based on motion of the subject due to cardiac activity, and may operate without contact with the subject. Example systems may provide an interrogation signal to the subject. Reflected signals from the subject are incident on a microphone array. The reflected signals may be processed and beamformed using a set of beamforming weights. The beamforming weights may be selected in a manner to reduce components of the reflected signals due to breathing motion of the subject while increasing the relative contribution of the reflected signals due to cardiac activity. The beamformed signal may provide a waveform indicative of heart beats. Inter-beat intervals, heart rates, and/or other health metrics may be calculated based on the waveform.

  • Patent number: 11806177
    Abstract: Various noncollimated single photon emission computed tomography (SPECT) technologies are described herein. An example device includes an array of detectors configured to detect a flux of first photons transmitted from a field of view (FOV) over time. The device also includes an attenuator disposed between the array of detectors and the FOV. The attenuator is configured to move over time and to attenuate second photons emitted from the source. In various implementations, the attenuator is not a collimator. Based on the fluxes of the first photons detected by the detectors, and the position of the attenuator over time, an imaging system may be configured to generate an image of the FOV.

  • Patent number: 11808734
    Abstract: Methods for nanopore-based protein analysis are provided. The methods address the characterization of a target protein analyte, which has a dimension greater than an internal diameter of the nanopore tunnel, and which is also physically associated with a polymer. The methods further comprise applying an electrical potential to the nanopore system to cause the polymer to interact with the nanopore tunnel. The ion current through the nanopore is measured to provide a current pattern reflective of the structure of the portion of the polymer interacting with the nanopore tunnel. This is used as a metric for characterizing the associated protein that does not pass through the nanopore.

  • Patent number: 11803043
    Abstract: Apparatuses, systems, and methods for dynamically shaped focal surface with a scanning microscope. A microscope (e.g., a scanning confocal microscope) may use a scanning element to scan an illumination beam to generate a focal region. The scanning element may include multiple degrees of freedom, such as rotation and translation along orthogonal axes. For example, if the illumination beam is a line focus, rotation along a first axis and translation along a second orthogonal axis may sweep the line focus across a focal surface which is substantially flat and normal to the second axis. In some embodiments, the microscope may be a dual-axis handheld microscope, where a single objective in a handheld housing is used to both direct the scanned illumination beam and receive the collected light.
