Abstract: The present invention relates to a device and method for shifting a fluid within a fluid channel. The device comprising: - a fluid channel (20) comprising at least one chamber (15), each chamber (15) being filled with a fluid (12) comprising an electrolyte and having at least two inlets (17), wherein each inlet (17) has a cross-section which is smaller than a cross-section of the at least one chamber (15); - a sealing control element (13) being enclosed in the fluid (12) of the fluid channel (20) for sealing the at least one chamber (15) and controlling a shift of the fluid (12) within the fluid channel (20) in response to a control signal (30); and - at least one pair of electrodes (8) arranged such that the electrodes (8) are in fluidic contact with the at least one chamber (15) for causing, in response to the control signal (30), an electrocapillary force acting on the sealing control element (13); wherein the sealing control element (13) has a surface tension which is higher than a surface tension of the fluid (12), such that in the absence of the control signal (30) at least a portion of the sealing control element (13) is trapped in one of the at least one chamber (15) due to an intrinsic capillary force, thereby sealing said one of the at least one chamber (15).

Abstract: The present invention relates to a method of manufacturing a metal mold for replicating a component having a predetermined three-dimensional shape, the manufacturing method comprising: (a) fabricating a glass-based mold by using a moldable nanocoposite comprising an organic binder and glass particles dispersed therein, the glass-based mold having the predetermined three-dimensional shape; and (b) replicating the glass-based mold obtained in step (a) by melting a metal inside the glass-based mold or by melting a metal outside the glass-based mold and pouring it onto or into the glass-based mold, followed by cooling, or by pressing the glass-based mold into a malleable metal substrate, thereby obtaining the metal mold for replicating the component, the metal mold having the predetermined three-dimensional shape inverted. Further, the present invention relates to a method of replicating a component having a predetermined three-dimensional shape, wherein the metal mold obtained by the manufacturing method is used for replicating the component, wherein the glass particles of the moldable nanocomposite comprise a first type of glass particles having a diameter in the range from 5 nm to 500 nm.
