  • Patent number: 11366061
    Abstract: An approach is described that combines distinct properties of a specialized porous nitrocellulose film (PNC) with quantum nanoparticles to create an improved assay and detection sensitivity, permitting the development of a camera-based imaging system for fluorescent detection of macromolecules in microarray format. The two properties of PNC that facilitate the approach are an extraordinarily high binding capacity and a newly observed internal scattering of light. Quantum nanoparticles complement these PNC properties by providing a higher level of emitted light than the fluorescent dyes in common microarray use. Overall, the approach allows for instrument cost savings, reduced imaging time, and the ability to remotely image.

  • Patent number: 11112233
    Abstract: Aspects of the subject technology relate to an apparatus for self-mixing particulate-matter sensing using a vertical-cavity surface-emitting laser (VCSEL) with extrinsic photodiodes. The apparatus includes a dual-emitting light source disposed on a first chip and to generate a first light beam and a second light beam. The first light beam illuminates a particulate matter (PM), and a light detector extrinsic to the first chip measures the second light beam and variations of the second light beam and generates a self-mixing signal. The variations of the second light beam are caused by a back-scattered light resulting from back-scattering of the first light beam from the PM. The light detector is coupled to the dual-emitting light source. The direction of the second light beam is opposite to the direction of the first light beam, and the second light beam is directed to a sensitive area of the light detector.

  • Patent number: 10929641
    Abstract: An automated microscope system is described that detects dicentric chromosomes (DCs) in metaphase cells arising from exposure to ionizing radiation. The radiation dose depends on the accuracy of DC detection. Accuracy is increased using image segmentation methods are used to rank high quality cytogenetic images and eliminate suboptimal metaphase cell data in a sample based on novel quality measures. When a sufficient number of high quality images are detected, the microscope system is directed to terminate metaphase image collection for a sample. The microscope system integrates image selection procedures that control an automated digitally controlled microscope with the analysis of acquired metaphase cell images to accurately determine radiation dose. Early termination of image acquisition reduces sample processing time without compromising accuracy. This approach constitutes a reliable and scalable solution that will be essential for analysis of large numbers of potentially exposed individuals.

    Abstract: A novel SH-SAW biosensor capable of non-invasive and touch-free detection of cancer cell viability and growth or proliferation in two-dimensional (2D) and three-dimensional (3D) cell cultures as well as stem cell regeneration as it pertains to cancer cell biology and anti-cancer drug development is presented. The biosensor includes two pairs of resonators including interdigital transducers reflecting fingers to quantify mass loading by the cells in suspension as well as within a tumoroid culture platform. The biosensor can be part of a perfused 3PNS-tumoroid system that is amenable to real-time non-invasive monitoring of the cell proliferation, viability, and multiplexed detection of key physiologic and clinical biomarkers.

  • Patent number: 10509007
    Abstract: Interference signals from other gases in an air sample are eliminated by flowing an air sample directly to an electrochemical gas sensor and subsequently flowing an air sample through a selective scrubber and removing the target gas of interest before flowing the sample to the electrochemical gas sensor. The difference in responses of the electrochemical gas sensor is directly proportional to the concentration of the target gas of interest in the air sample.

  • Patent number: 10495637
    Abstract: A universal sensor fabrication approach, molecular substrate imprinting technique, which utilizes the interaction between molecular building blocks and the surface of a transducer to develop specific molecular recognition cavities has been established. Integration of molecular recognition cavities with the surface of a nanoscale transducer will result in a nano-tunneling effect that takes place which will provide a sensor or a device that exhibits new properties not already exhibited by either the molecular recognition cavities on a bulk transducer or the nanotransducer material. One of the new properties of this nano-tunneling effect is that a universal potentiometric molecular sensor can be fabricated and used to detect any compounds, whether they are ions or molecules, with enhanced selectivity, sensitivity, and stability when molecular recognition cavities or elements are integrated on the surface of a nanoscale transducer.

  • Patent number: 10371688
    Abstract: A sensing system for explosives is provided. The sensor is based on a layered structure of approximately a monolayer of a fluorophore deposited onto a few nm of a transparent polymer, supported by a substrate. The fluorophores can be xanthene laser dyes, which have high quantum yields, and the polymers can be commodity materials polymethylmethacrylate and polyvinylidene difluoride. The different fluorophore/polymer combinations give different emission responses to analytes, including both signal quenching and enhancement. The pattern of responses can be used to identify the analyte. The common explosives TNT, PETN, RDX, HMX, and TATP as gas phase species can all be uniquely identified at room temperature using only the natural vapor pressure of the explosive to deliver sample to the sensor.

Sample-containing fluid flows from the sample well to a droplet-generation region of the device via the first channel. Carrier fluid flows from the carrier well to the droplet-generation region via the second channel. Sample-containing droplets and carrier fluid flow from the droplet-generation region to the droplet well via the third channel.
