    摘要: A method of determining the transfection status of a plurality of cells comprising the steps of providing a population of cells that have been subjected to a cell membrane disruption treatment, passing a focussed stream of the population of cells in a carrier liquid along a microfluidic channel having a detection zone comprising a pair of detection electrodes configured to detect electrical impedance across the channel in the detection zone, detecting a change in the electrical impedance across the channel in the detection zone corresponding to each of the plurality of cells passing the detection zone, comparing the change in electrical impedance for each cell with a reference change in electrical impedance, and calculating the transfection status of the plurality of cells based on the comparison.

    摘要: A device for assessing the status of a fluid containing cells of mammalian origin, the device comprises a cartridge (2) having an enclosed fluidic channel (28), an assay area (22) disposed within the fluidic channel (28) which is covered by at least one agent capable of selectively recruiting at least one type of cell contained within the mammalian fluid, an inlet port (25) for the fluidic channel, an outlet port (24) for the fluidic channel and a piercing means (51) adapted for connecting to a sealed container (4) containing the cell containing fluid by puncturing the container. The inlet port and piercing means are adapted to provide fluid communication between the fluidic channel and the sealed container when the sealed contained is punctured by the piercing means. The outlet port is adapted for fluid communication with a syringe (3) such that actuation of the syringe provides controlled flow of fluid over the assay area to achieve desired physiological shear stress conditions for the type of cell being recruited at the assay area. The cartridge is adapted for integration with a read out instrument for acquiring optical signal at the assay area of the channel.

    摘要: This invention relates to the field of microfluidic flow cytometry and more generally microfluidic techniques for analysis of particulate-containing fluids. It deals with the improvements to such technologies in order to identify subsets of particles or sub-populations of cells that differ in their properties, and, if necessary, separate the said identified sub-populations of cells, e.g. sex of semen cells, alive cells from the dead ones, cancerous cells from the healthy ones, subsets of viruses, bacteria or subsets of particles. This invention disclosure deals with the apparatus and the method for detection of cells or particles based on measurements of complex AC impedance between electrodes across the flow of fluid containing such cells or particles.
