摘要:
The present teachings comprise a device and method for lysing and/or purifying biological sample. The device can comprise a cartridge having a chamber containing a biological sample receiving region, a plurality of electrodes, and one or more sieving matrices. The electrodes can be configured to lyse the biological sample through the production of a pulsed electrical field. The electrodes can also be configured to heat lyse the biological sample. The electrodes can also be configured to electrophoretically move the biological sample through one or more sieving matrices. A portion of the sample can be isolated on a membrane. The portion of the sample isolated on the membrane can be amplified and detected. A portion of the sample can be isolated in a collection area present in the cartridge. The portion of the sample isolated in the collection area can be removed from the cartridge.

This invention provides methods and systems for flushing, washing, and priming microscale devices for reuse. Washing and priming methods include flowing solutions from a manifold to flush wells and microchannels of a microfluidic chip. Systems include manifolds adapted to seal and flow solutions or gasses into chip wells. Devices include microfluidic devices with data storage modules to track the reprocessing status of the microscale devices.
摘要:
A method and miniature analytical device with thermal regulation of reactant using a localized heat source capable of emitting electromagnetic radiation, such as light emitting diodes (“LED”s) and vertical cavity surface emitting lasers (“VCSEL”s), generating internal heat, such as resistive, inductive and Peltier heaters, or external heating. The miniature analytical device comprises of array of temperature-controlled zones to restrict the volume heated and localize the heating by having the localized heat source comprise an array of emitters or heaters.

摘要:
The present invention is an automated microfluidic chip processing apparatus that includes a deck for holding at least one microfluidic chip and capable of being accessed by a liquid handling system, a fluid control system, and a detection system, wherein a chip handling device transports the chip from the deck to the fluid control system and the detection system. The present invention also includes a chip for use with an automated microfluidic chip processing apparatus, and a method for processing a microfluidic chip using such an apparatus.
摘要:
A device for sampling blood from the skin of a patient by puncture. The device includes one or more lancets for lancing the skin and a fluid-conducting plate unit for transporting blood from the lancing wound. The plate unit has one or more channels for conducting fluid to one or more target locations. Preferably there is a first channel for conducting away a first portion of fluid that contains more of a fluid that is emitted initially (initial fluid) from the puncture wound and a second channel for conducting a second portion of fluid that contains less of the initial fluid from the puncture wound. Blood is drawn into the channels by capillary force. The device can be used to lance the skin and obtain a representative sample of blood with relatively simple procedures.
摘要:
A multi-shaft apparatus for incising a substrate of soft resilient material such as a body tissue. The incising apparatus includes two or more incision shafts each having a distal edge. The shafts are not affixed to each other and are allowed to slide against each other to drive the distal edges alternately against the substrate to incise the substrate. In the case of incising a body tissue, such alternate motion would result in less pain to the patient than a puncture resulting from a sharp jab by a sharp shaft of similar size to the shafts.
