A playing piece (10, 20) for use in a board game, and comprising at least one shapeable segment (11, 21), an input (12) and shaping means (13). An input signal from an outside control unit (17) is received at the input (12), the input signal representing a particular shape and/or size of the playing piece (10, 20). The shaping means (13) couples the input (12) to the shapeable segment (11, 21) to deform the shapeable segment (11, 21) in dependence of the input signal, for obtaining the particular shape and/or size of the playing piece (10, 20).

According to an aspect of the present invention, a device for fragmenting molecules in a sample by ultrasound is provided. The device comprises a planar-shaped cartridge and a fragmentation instrument that has a vessel-like shape. By means of applying under-pressure in the fragmentation instrument the cartridge is pulled towards the fragmentation instrument and therefore spatially closes a fluid compartment that is comprised by the fragmentation instrument. Afterwards, an ultrasound treatment of the sample, which is comprised in a sample compartment of the cartridge, may be processed. A sealing layer is provided in between the cartridge and the fragmentation instrument in order to hold the fixation of the cartridge tightly and in order to provide for leakage prevention out of the fluid compartment.
摘要:
A device or support, system and method are provided for precisely targeted and/or highly controlled interaction with a targeted cell or tissue in a body, with the support providing an ergonomic connecting interface for selectively connecting the support to a cell or tissue with at least minimal adverse affect to such cell or tissue, the system providing a remote facility that may be operatively associated with the support, and the method providing steps for employing the support and/or system so as to, inter alia, improve treatment, diagnostic and/or monitoring techniques and increase sensitivity and specificity with respect to interacting with, for example, diseased or abnormal cells or tissue without adversely effecting surrounding healthy cells or tissue, and/or the body in general.

The present invention provides micro-fluidic systems, a method for the manufacturing of such a micro-fluidic system and a method for controlling or manipulating a fluid flow through micro-channels of a such a micro-fluidic system. Herefore, an inner side of a wall of a microchannel is provided with actuator elements which can change shape and orientation as a response to an external stimulus. Through this change of shape and orientation the flow of a fluid through a microchannel may be controlled and manipulated.
摘要:
A device for transporting magnetic or magnetizable beads over a transport surface includes a chamber holding magnetic or magnetizable beads in a fluid, a transport element including the transport surface within the chamber, and a current wire structure including at least two sets of meandering current wires arranged on a side of the transport element opposite to the transport surface. The at least two sets are displaced with respect to each other in at least two directions. A switching unit switches currents individually applied to the sets of current wires according to a current driving scheme resulting in a transport of the beads over the transport surface.
摘要:
The present invention relates to a device for the specific selection of target molecules, comprising: (a) at least one reaction zone comprising a microarray, wherein the microarray comprises a substrate, on which one or more species of capture molecules are immobilized, comprising one or more temperature control and/or regulating units for controlling and/or regulating the temperature within the zone; (b) at least one non-reaction zone comprising one or more temperature control and/or regulating units for controlling and/or regulating the temperature within the zone, which is in fluid connection with the reaction zone; and (c) at least one transportation means capable of generating and/or regulating a fluid flow between said reaction zone (a) and said non-reaction zone comprising one or more temperature control and/or regulating units (b). The present invention further relates to a device for the specific selection of target molecules wherein the immobilized capture molecules are organized in the microarray in the form of spots, elongated spots and/or lines. In a further aspect the present invention relates to a method of specifically selecting target molecules, comprising the introducing a medium to such a device, performing interaction reactions in a reaction zone, transporting not interacted or not bound target molecules to a zone allowing reactivation of the target molecules and performing additional interaction reactions with the reactivated target molecules at the reaction zone, as well as the use of such a device for specifically selecting target molecules, e.g. for target enrichment also referred to as microarray based genome selection (MGS) in the literature.
