  • Patent number: 11319575
    Abstract: An imaging system and method provides automated microbial growth detection for antibiotic sensitivity testing. A processing system having an image sensor for capturing images of an inoculated culture plate having antibiotic disks disposed on the culture media captures images of the plate at separate times (e.g., first and second images). The system generates pixel characteristic data for pixels of the second image from a comparison of the first image and second image. The pixel characteristic data may be indicative of plate growth. The system may access growth modeling data concerning the antibiotic disk(s) and generate simulated image data with a growth model function. The growth model function uses the growth modeling data. The simulated image data simulates growth on the plate relative to the disk(s). The system compares the simulated image and the pixel characteristic data to identify pixel region(s) of the second image that differ from the simulated image.

  • Patent number: 11305283
    Abstract: Biological activity in holding pens in a micro-fluidic device can be assayed by placing in the holding pens capture objects that bind a particular material of interest produced by the biological activity. The biological material of interest that binds to each capture object can then be assessed, either in the micro-fluidic device or after exporting the capture object from the micro-fluidic device. The assessment can be utilized to characterize the biological activity in each holding pen. The biological activity can be production of the biological material of interest. Thus, the biological activity can correspond to or arise from one or more biological cells. Biological cells within a holding pen can be clonal cell colonies. The biological activity of each clonal cell colony can be assayed while maintaining the clonal status of each colony.

  • Patent number: 11022888
    Abstract: The formation of microporous surfaces through polymer induced phase separation in a photopolymer solvent mixture using photopolymerization via light self-focusing and self-trapping. The self-trapping of light sets fixed regions of brightness and darkness, sustained by the polymerization of light, and then wave guiding within the substrate. Phase separation occurs with the solvent phase separating in the regions of darkness and crosslinking in the regions of brightness. Upon removal of the solvent, precise and uniformly dispersed pores are created in the surface. The pore size and spacing may be tuned by adjusting the weight fraction of the photopolymer solvent mixture as well as through changes in the mask pattern.

  • Patent number: 10261077
    Abstract: A subtractive corrective assay device and methodology, whereby ail required binding and label detection reagents are initially located within the detection zone. Application of a magnetic field is used to selectively remove bound label from the detection zone by means of paramagnetic particles. The relationship between measured label concentration before and after the application of a magnetic field within the detection zone is used to accurately measure analyte concentration within the sample.

  • Patent number: 10252907
    Abstract: A group of micro-objects in a holding pen in a micro-fluidic device can be selected and moved to a staging area, from which the micro-objects can be exported from the micro-fluidic device. The micro-fluidic device can have a plurality of holding pens, and each holding pen can isolate micro-objects located in the holding pen from micro-objects located in the other holding pens or elsewhere in the micro-fluidic device. The selected group of micro-objects can comprise one or more biological cells, such as a clonal population of cells. Embodiments of the invention can thus select a particular group of clonal cells in a micro-fluidic device, move the clonal cells to a staging area, and export the clonal cells from the micro-fluidic device while maintaining the clonal nature of the exported group.

  • Patent number: 10233505
    Abstract: The present invention is concerned with PCR-based detection methods and kits for the identification, differentiation, and quantification of different bacterial strains (e.g., Gram-negative bacterial strains), and also association of two or more PCR-positive genes to a single genome. The methods generally comprise carrying out PCR reactions using at least a first PCR primer set and/or probe for at least one target nucleic acid; and a second PCR primer set and/or probe for at least a second target nucleic acid. Positive PCR reaction products are then detected to determine test samples containing positive PCR reaction products for both the first and second target nucleic acids. This information can be used to calculate the gene association rate to determine whether the sample contains, for example, Shiga toxin-producing E. coli of the O-type serogroup.

  • Patent number: 10221440
    Abstract: The invention relates to medicine and to veterinary medicine, and specifically to means for determining the sensitivity of various microorganisms, including bacteria and fungi, to antimicrobial substances. The method for determining the sensitivity of microorganisms to antimicrobial substances comprises taking biological material, incubating microorganisms contained therein on a nutrient medium, introducing an antimicrobial substance to be investigated into the nutrient medium and subsequently assessing the result. A dense, rich nutrient medium is used for cultivating the microorganisms. The antimicrobial substance being investigated is introduced into the nutrient medium prior to cultivation of the microorganisms in a concentration close to the maximum concentration achievable at the location at which the biological material is taken. The sensitivity of the microorganisms to the antimicrobial substance is assessed after the appearance of visible growth of microorganisms in a control culture.

  • Patent number: 10163629
    Abstract: Systems and methods for processing films on the surface of a substrate are described. The systems possess aerosol generators which form droplets from a condensed matter (liquid or solid) of one or more precursors. A carrier gas is flowed through the condensed matter and push the droplets toward a substrate placed in a substrate processing region. An inline pump connected with the aerosol generator can also be used to push the droplets towards the substrate. A direct current (DC) electric field is applied between two conducting plates configured to pass the droplets in-between. The size of the droplets is desirably reduced by application of the DC electric field. After passing through the DC electric field, the droplets pass into the substrate processing region and chemically react with the substrate to deposit or etch films.

  • Patent number: 10101349
    Abstract: A test management system is presented. The system comprises an analyzer to perform tests a sample according to a first set of instructions, a manager module connected to the analyzer, and a first order interface connected to the manager module. The manager module directs activity of the analyzer according to a second set of instructions. The first order interface receives an order for a first analytical test and a second analytical test and transmits the order to the manager module. If the order is for the first analytical test, the test manager module forwards the order directly to the analyzer and the sample is analyzed by the analyzer according to the first set of instructions. If the order is for the second analytical test, the manager module handles the order according to the second set of instructions and generates and transmits secondary test requests to the analyzer.
