Abstract:
The present invention provides a method for obtaining sequencing-based information from cells/nuclei, the method comprising (a) a first barcoding of cells and/or nuclei of a group of cells and/or nuclei comprising interacting cells with one or more group-specific barcode sequence(s) or a group-specific combination of one or more barcode sequence(s); (b) a second barcoding of nucleic acid molecules contained in and/or attached to individual cells and/or nuclei from said group of cells/nuclei with a cell/nucleus-specific barcode sequence; and (c) sequencing of the barcoded nucleic acid sequences.
Abstract:
Techniques are described for automated microinjection of substances, such as genetic material, into single cells in tissue samples. An example system comprises a robotic manipulator apparatus configured to hold and position a micropipette. Furthermore, the system comprises a microscope camera positioned to observe an injection site. A computing device receives image data from a microscope camera of the system, where the image data represents an image of a tissue sample. The computing device receives, via a user interface, an indication of a line traced by a user on the image of a tissue sample. In response, the computing device controls the robotic manipulator apparatus to move a tip of the micropipette along a path defined by the trajectory line. The pressure controller injects a gas into the micropipette to eject a substance out of the micropipette at one or more points along the path defined by the trajectory line.
Abstract:
There is provided a particle detection apparatus (30) comprising: a channel (32) including an inlet and at least one channel wall, the inlet permitting light to be introduced into the channel (32), the or each channel wall being arranged to define a channel path through which light may propagate; a light source (34) configured to introduce light into the channel (32) via the inlet, the channel (32) being shaped to guide the light to propagate along the channel path for illuminating a particle or a plurality of particles located in the channel path; and a monitoring device (36) configured to detect scattered light that is created by the illumination of the or each particle by the guided light and that leaves the channel (32) by passing through the or each channel wall.
Abstract:
The silicon-based photomultiplier device comprises a substrate (1), a first layer (2) of a first conductivity type, a second layer (3) of a second conductivity type formed on the first layer, wherein the first layer (2) and the second layer (3) form a p-n junction, wherein the first layer (2) and the second layer (3) are disposed on or above the substrate (1). A material layer (15) between the substrate (1) and the first layer (2) fulfils the function of a light absorber, thereby efficiently suppressing crosstalk between adjacent cells of the device. Material layer (15) may further serve as an electrode for readout of electrical signals from the device.

Abstract:
The present invention provides a multifunctional coating having antimicrobial activity and the capability to regulate cell adhesion, comprising, deposited on a substrate surface, i) an optional anchoring layer, ii) a Zn-release layer deposited on the anchoring layer or directly on the substrate surface and iii) a functional barrier layer deposited on the Zn-release layer, wherein the functional barrier layer is capable to slow down the diffusion of Zn from the Zn-release layer through the barrier layer and wherein the surface of the functional barrier layer regulates cell adhesion. In a more specific embodiment of the invention, the polymeric film of the Zn-release layer has been formed by plasma assisted polymerisation of zinc-organic precursors, e.g. Zn (acac) 2 , bis (pentafluoro-phenyl ) -zinc, and zinc-hexafluoro acetylacetonate.
Abstract:
The invention relates to an appliance (18) for at least partially disinfecting/sterilising a contaminated surface (21), wherein the appliance (18) comprises an integrated plasma source for at least partially disinfecting/sterilising the surface by generating a non-thermal atmospheric plasma on the surface thereby reducing the concentration of pathogenic germs on the surface.
Abstract:
Die Erfindung betrifft eine Düsenanordnung (1) zur Abgabe eines Fluids, insbesondere zur Einspritzung des Fluids in eine Vakuumkammer, mit einem Düsenkörper (2) mit einem durchgehenden Düsenkanal (9) und einer ausgangsseitig ausgebildeten Düsenöffnung (10) zur Abgabe des Fluids sowie mit einer koaxial zu dem Düsenkanal (9) verlaufenden Zuleitungskapillare (8) zur Zuführung des einzuspritzenden Fluids.
