Analysis apparatus
11366126 · 2022-06-21 · ·

Provided is an analysis apparatus having a control part having a preparatory action setting part for determination of whether the first and second controls are performed or the third and fourth controls are performed. The first control sets a sleep-planned part to a sleep state at a first time point when the state of non-use of the analysis apparatus has lasted for a predetermined time length, and then causes performance of a preparatory action by a first predetermined part; the second control resumes the operation of the analysis apparatus when a command signal to resume the operation is received; the third control places a sleep-planned part in a sleep state at a second time point when the state of non-use has lasted for a time length; and the fourth control causes a preparatory action of a second predetermined part to resume operation.

Real time autonomous surveillance of pathogens

The present invention relates, in part, to systems configured to obtain samples from an organism in an autonomous manner. Such systems can employ a cartridge configured to provide bait to attract an organism, as well as channels to store and/or test samples obtained from the organism.

DETECTION DEVICE AND DETECTION METHOD OF DOT IMMUNOBLOTTING DETECTION

The present invention provides a detection device of dot immunoblotting detection, including a negative pressure suction device, a hole plate, a hose for connecting the hole plate with the negative pressure suction device, and a nitrocellulose membrane in tight fit with the upper end surface of the hole plate. The present invention further provides a detection method of dot immunoblotting detection, including preparation, sample injection, blocking, incubation of a primary antibody, incubation of a secondary antibody, development and analysis. The detection method performs negative pressure suction through the negative pressure suction device, which is favorable for concentrating samples during sample injection and avoiding the influence, caused by cross contamination after diffusion of the samples, on an experimental result, and the experimental result is more accurate.

20220170929 · 2022-06-02 · ·

The present disclosure relates to systems and methods for determination of analyte concentrations in solution using materials that are pre-dispensed and dried on conjugate pads or other solid substrates. The solution including the analyte can reconstitute the dried material within a vial to produce a specified concentration of material in the vial. The resulting solution can be used in lateral flow testing.

IMMUNOASSAY METHOD AND IMMUNOASSAY DEVICE

The present invention relates to an immunoassay method and an immunoassay device.

According to an aspect of the present invention, provided is an immunoassay device including: a stage capable of accommodating a plurality of cartridges having a plurality of wells; a solution transfer unit including a plurality of tips, which are movable relative to the stage and disposed to correspond to a position of the cartridge so as to suction a solution stored in each of the wells or discharge the suctioned solution from the well; and a control unit controlling the stage and the solution transfer unit to be relatively movable and controlling suction or discharge of a content into/from the plurality of tips.

Micro-plate reader for ELISA testing

A micro-plate reader for use with a portable electronic device having a camera includes an opto-mechanical attachment configured to attach/detach to the portable electronic device and includes an array of illumination sources. A slot in the opto-mechanical attachment is dimensioned to receive an optically transparent plate containing an array of wells. Optical fibers are located in the opto-mechanical attachment and transmit light from each well to a reduced size header having, wherein the fiber array in the header has a cross-sectional area that is ≤10× the cross-sectional area of the wells in the plate. A lens located in the opto-mechanical attachment transmits light from the header fibers to the camera. Software executed on the portable electronic device or other computer is used to process the images to generate qualitative clinical determinations and/or quantitative index values for the separate wells.
