Abstract: The invention provides a system (1) for performing sperm analysis and selection based on sperm cell morphology of sperm cells (6) in a fluid (5), the system (1) comprising: (i) a fluid flow channel (2) for transport of said fluid (5), the fluid flow channel (2) comprising an inlet (10) an analyzing zone (40) configured downstream from said inlet (10) and comprising a first pair of electrodes (41) comprising a first intra-electrode distance (dl), a sorting zone (50) configured downstream from said analyzing zone (40) and comprising a sorting device (51), and outlets (80, 90, . . .

Abstract: The invention provides a lab-on-a-chip device comprising a micro channel for a fluid, wherein the micro channel comprises a circumferential channel wall, wherein the channel wall comprises a first electrode, a second electrode, and a floating third electrode. The device can be used in a method for the analysis of an analyte fluid comprising flowing the analyte fluid through the channel of the electronic lab-on-a-chip device by measuring an electric signal between the first and the second electrode, especially measuring the electrical impedance between the first electrode and the second electrode. This may be used for instance for the analyses of mammalian semen.

Abstract: The invention provides a method for taking a plurality of samples (200) from a substrate (40) with sample material (20) by using an optical microscope (1000) and a stamp (50). At least part of the stamp (50) is transparent and the stamp (50) is arranged in front of the objective (41). The elevations (58) of the stamp (50) are contacted with sample material (20) in a substrate (40). The samples (200) may be replicated to other substrates.

Abstract: The invention relates to the field of microbiology. Provided is a method which is particularly powerful for High Throughput Screening (HTS) purposes. More specific a high throughput method for determining heterogeneity or interactions of microorganisms is provided.

Abstract: The invention relates to a biochip (5) comprising a porous support (10), wherein the porous support (10) comprises at least one surface coated with a coating, preferably a polymer coating (20), wherein the coating is patterned with a micro compartments (25) pattern, with the support providing a bottom surface to the compartments and the coating providing edges to the compartments, and wherein the pattern comprises at least 400 compartments per mm2. The biochip (5) can be obtained by a process comprising providing a porous support (10); coating at least one surface of the support with a coating (20); arranging between the coated surface and an ion etching device a shadow mask with a predetermined hole pattern; and ion etching at least part of the coating such that a patterned coating with micro compartments (25) is obtained.
