Automated real-time particle characterization and three-dimensional velocimetry with holographic video microscopy
An in-line holographic microscope can be used to analyze on a frame-by-frame basis a video stream to track individual colloidal particles' three-dimensional motions. The system and method can provide real time nanometer resolution, and simultaneously measure particle sizes and refractive indexes. Through a combination of applying a combination of Lorenz-Mie analysis with selected hardware and software methods, this analysis can be carried out in near real time. An efficient particle identification methodology automates initial position estimation with sufficient accuracy to enable unattended holographic tracking and characterization.

METHODS AND APPARATUS FOR DETERMINING PARTICLE CHARACTERISTICS BY UTILIZING FORCE ON PARTICLES
An instrument for measuring characteristics of particles. A particle sample is introduced into a sample cell. The sample particles are subjected to gravitational or centrifugal forces wherein particle motion is dependent upon particle characteristics. The particles are illuminated by an illumination device to produce light scattered by the particles. The light is detected by at least one detector. Characteristics of the particles are determined from the detector signals.
METHODS AND COMPOSITIONS FOR MULTIPLE-PARAMETER SINGLE-CELL ANALYSIS USING SPECTRALLY ENCODED MICROBEADS
The invention provides compositions and methods for associating data from phenotypic analysis of a single cell with sequencing data from the single cell using spectrally-encoded microbeads.
Device And Method For Detecting A Concentration Of Predetermined Particles On The Basis Of Their Morphological Properties In Air
A device (1) for detecting a concentration of predetermined particles, particularly viruses, in air (3) with organic and/or inorganic aerosol particles, has a supply unit (10), an imaging unit (20), an image acquisition unit (40) and an evaluation unit (50). The supply unit (10) binds the aerosol particles as particles in a fluid (4). The imaging unit (20) operates on the functional principle of a scanning electron microscope in order to generate an enlarged image of the particles contained in the fluid (4). The image acquisition unit (40) acquires and transmits the image. The evaluation unit (50) evaluates the particles depicted in the image. The evaluation unit (50) automatically detects morphological properties of the particles depicted in the image and compares the detected morphological properties with morphological properties of the predetermined particles. Through the comparison, it determines a proportion and/or number of predetermined particles in the image and the concentration of the predetermined particles in the air (3).
SYSTEMS FOR CELL CONTROL
The disclosure relates to growing cells, directing cells to grow into specified cell types, genetically and physically manipulating cells, and addressing one or more individual cells within a mixed cell population. Aspects of the disclosure relate to vectors useful to induce developmental changes in cells, in which those vectors have a temporal component. Vectors of the disclosure encode a controllable, temporal series of events. Once the vectors are delivered into target cells, a series of discrete and different genetic events may be induced. The disclosed methods generally provide for the temporal encoding of multiplex genetic effectors in vector format for cell state transitions.
3D PARTICLE IMAGING IN PHARMACEUTICAL CONTAINERS
A method for 3D imaging of a sample, in a vessel having a longitudinal axis orthogonal to a horizontal plane, includes capturing, by at least three cameras located at different positions around the vessel, respective 2D images of the sample. Each image comprises pixels having associated pixel values. The optical axis of a first camera is inclined or declined at a first angle relative to the horizontal plane, with the first angle being greater than or equal to zero degrees. The optical axis of a second camera is inclined or declined at a second, larger angle relative to the horizontal plane. The method also includes generating a 3D image of the sample based on the pixel values associated with the 2D image pixels, and one or more look-up tables that collectively indicate, for pixels in each image, expected paths for light traversing the vessel and the sample.
CELL EVALUATION DEVICE, OPERATION METHOD FOR CELL EVALUATION DEVICE, AND OPERATION PROGRAM FOR CELL EVALUATION DEVICE
There is provided a cell evaluation device including an acquisition unit that acquires a cell image in which a nerve cell having a cell body, an axon, and a dendrite is shown; a first specifying unit that specifies the axon in the cell image; a second specifying unit that specifies spines formed on the dendrite in the cell image; a selection unit that selects a synapse-estimated spine, which is estimated to constitute a synapse with the axon and is close to the axon specified in the first specifying unit, from the spines specified in the second specifying unit; and a display control unit that performs control to display the synapse-estimated spine in a display form different from that of other spines in the cell image.
Device, System and Method For The Detection and Screening of Plastic Microparticles
A device, system and method for the detection and screening of plastic microparticles in a sample is disclosed. A nanoporous silicon nitride membrane is used to entrap plastic microparticles contained in the sample. The sample may be a water sample, an air sample, or other liquid or gas sample. The entrapped plastic microparticles are then heated or otherwise processed on the nanoporous silicon nitride membrane. An imaging system observes the nanoporous silicon nitride membrane with tic entrapped plastic microparticles to determine the type and quantity of the various plastic microparticles that are entrapped on the membrane.
