Abstract: The invention lies in the technical field of cell biology and transplantation medicine. It concerns devices and methods for rapid and noninvasive analysis or checking of biological samples, especially for sterility control, for characterization of infectious particles and microorganisms contained in the biological sample and for characterization of tissue cells and transplants. The main areas of application of the invention are biotechnological production of pharmacological active ingredients and therapeutic agents as well as transplantation medicine.

Abstract: Method and device for the plasma treatment of a substrate in a plasma device, wherein—the substrate (110) is arranged between an electrode (112) and a counter-electrode (108) having a distance d between a surface area of the substrate to be treated and the electrode, —a capacitively coupled plasma discharge is excited, forming a DC self-bias between the electrode (112) and the counter-electrode (108), —in an area of the plasma discharge between the surface area to be treated and the electrode having a quasineutral plasma bulk (114), a quantity of at least one activatable gas species, to which a surface area of the substrate to be treated is subjected, is present —it is provided that a plasma discharge is excited, —wherein the distance d has a value comparable to s=se+sg, where se denotes a thickness of a plasma boundary layer (119) in front of the electrode, and sg denotes a thickness of a plasma boundary layer (118) in front of the substrate surface to be treated or —wherein the quasineutral plasma bulk (114

Abstract: The invention relates to a thermochromic polymer layer and also a method for production thereof. The method is based on addition of a thermochromic colorant and if necessary further additives at the beginning of the extrusion process and subsequent extrusion to form the thermochromic polymer layer. Furthermore, the invention relates to a multilayer composite system comprising at least one thermochromic polymer layer and also at least one further layer.

Abstract: A device is disclosed for pipetting a liquid, comprising a pipette body enclosing a pipette volume, into which a fluid medium can be placed and in which an actuator that controllably displaces the medium in the pipette volume is provided, as well as a pipette tip, which can be connected to the pipette volume in a fluid-tight manner. The present invention is distinguished by the pipette volume and the pipette tip being connected via a fluid-tight connecting means directly or indirectly to each other in such a manner that the pipette tip is moveable relative to the pipette volume.

Abstract: Disclosed is a device and a process for examining cells using the patch-clamp method. A plane arrangement is used of a first number of micro-cuvettes for receiving cells and a plane arrangement of a second number of micro-pipettes which can be positioned in relation to the plane arrangement of micro-cuvettes in such a manner that a multiplicity of cells located in the micro-curvettes can be examined simultaneously.

Abstract: A connecting device is disclosed for operatively interconnecting a superscture element and an implant member having at least one bore, which device includes a rod member made of a material of construction having a high modulus of elasticity and which device further includes a projection means made of the same material of construction as used for the rod member, or a dissimilar material, and the device further including, as required, an envelope means. There are further disclosed an implant member which includes the aforesaid connecting device, and a method for arranging the connecting device in an implant member.
