System and method for anatomical pathology sample handling, storage, and analysis
A carrier strip having a plurality of areas for retaining anatomical pathology specimens may have a backing, a cover coupled to the backing along side regions located along opposite longitudinal edges of the carrier strip and along lateral intermediate regions positioned between each of the plurality of areas for retaining anatomical pathology specimens. The carrier strip may be configured to individually retain each of the anatomical pathology specimens in one of the plurality of areas for retaining anatomical pathology specimens between the backing and the cover. Diagnostic studies of anatomical pathology specimens may be facilitated by distributing a digital copy of an image of the specimen may be to a pathologist. A diagnosis may be received from the pathologist based on the digital image of the specimen.
Device and a method for collecting and transferring samples of biological material
A device for collecting, transferring and/or conserving samples of biological material, comprising at least: a support body having at least a housing seating for a conserving element for samples, the housing seating being configured for enabling removably housing the conserving element for samples of biological material, the support body being configured for maintaining at least a conserving portion of the conserving element accessible for depositing a sample when the conserving element is housed in the housing seating; an operating portion, movable between a first closed position in which it is arranged in proximity of said housing seating and at least an open position in which it is arranged in a distanced position from the housing seating; and engaging portion configured for selectively and removably engaging a sampling element for samples, in particular an element for buccal sampling, to the support body and/or to the operating portion.
A method for controlling timing of events in a microfluidic device and a timer microfluidic device
A method for controlling timing of events in a microfluidic device and a timer microfluidic device are disclosed. The method comprises adding a liquid on a first end of a microfluidic device at a first time t.sub.0, the liquid flowing by capillarity towards a second end; producing, by a battery (12) included in the microfluidic device, energy from a second time t.sub.start until a third time t.sub.end to feed an auxiliary device (16) connected to the battery (12). The battery (12) is sized and composed to provide a given amount of energy during a delivery energy time interval t.sub.operation, comprised between a time t.sub.on in which a voltage output of the battery (12) is above a threshold and a time t.sub.off in which the voltage output is below the threshold, to control the duration of an event including a selective activation and deactivation of said auxiliary device (16).
Devices And Method For Enrichment And Alteration Of Cells And Other Particles
The invention features devices and methods for the deterministic separation of particles. Exemplary methods include the enrichment of a sample in a desired particle or the alteration of a desired particle in the device. The devices and methods are advantageously employed to enrich for rare cells, e.g., fetal cells, present in a sample, e.g., maternal blood and rare cell components, e.g., fetal cell nuclei. The invention further provides a method for preferentially lysing cells of interest in a sample, e.g., to extract clinical information from a cellular component, e.g., a nucleus, of the cells of interest. In general, the method employs differential lysis between the cells of interest and other cells (e.g., other nucleated cells) in the sample.

More specifically, well plates are presented that comprising an array of wells configured to retain a plurality of beads suspended in a fluid during an assay procedure, each well in the array comprising a first trench and a second trench, wherein the working volume of each well is between about 25 uL and about 10 mL.
Method of processing dried samples using digital microfluidic device
Methods are provided for the preparation of a sample using a digital microfluidic platform and the optional subsequent mass analysis of an extracted analyte. A sample is dried, optionally on a solid phase support, and contacted with digital microfluidic array. An analyte present within the dried sample is extracted into an extraction solvent by electrically addressing the digital microfluidic array to transport a droplet of extraction solvent to the dried sample spot. The extracted sample may be dried and subsequently processed on the digital micro fluidic array for derivatization. The digital microfluidic device may further include an integrated microfluidic channel having an output aperture, and the method may further include contacting a droplet containing extracted analyte with the microfluidic channel and applying a suitable electric field for generating nano-electrospray, thereby enabling the device to be directly interacted with a mass analysis device.

Kit and method for collecting body fluid for medical diagnosis
A kit and method for collecting body fluid for medical diagnosis. In some embodiments, the method includes collecting a sufficient amount of body fluid and cells comprising nucleic acid, and applying a nucleic acid assay to detect pathogenic genomic material such as human papillomavirus mRNA and/or human papillomavirus DNA. In some embodiments, by testing fluid and cells, a sensitivity of the test is improved. In some embodiments, the method includes inserting an absorbing member into a body orifice, such as the vagina, for a time period such as 1-2 hours; retrieving the absorbing member and placing it in a sample container; extracting fluid from the absorbing member using a fluid extraction device, and testing the fluid. In some embodiments, the kit is a home use kit and the sample is self collected by a user.
MOVING MICRODROPLETS IN A MICROFLUIDIC DEVICE
The present invention relates to a system and method for moving samples, such as fluid, within a microfluidic system using a plurality of gas actuators for applying pressure at different locations within the microfluidic. The system includes a substrate which forms a fluid network through which fluid flows, and a plurality of gas actuators integral with the substrate. One such gas actuator is coupled to the network at a first location for providing gas pressure to move a microfluidic sample within the network. Another gas actuator is coupled to the network at a second location for providing gas pressure to further move at least a portion of the microfluidic sample within the network. A valve is coupled to the microfluidic network so that, when the valve is closed, it substantially isolates the second gas actuator from the first gas actuator.
