Abstract:
The invention relates to a component (4) of a biosensor, comprising at least one first device (6) for receiving a sample liquid, wherein the device (6) is connected via a distributor channel (7) to further receiving devices (8 to 11), into each of which a feed channel (71, 72, 73, 74) branching off from the distributor channel (7) opens, and the feed channels (71, 72, 73, 74) are arranged in succession in flow direction (S) of the sample liquid passed on through the distributor channel (7). In accordance with the invention, it is envisaged that, in the distributor channel (7), in each case between two immediately successive feed channels (71, 72; 72, 73; 73, 74) in flow direction (S), at least one region (K) for at least temporary slowing or stoppage of the capillary flow of the sample liquid has been inserted. It is thus possible to control the capillary flow of the sample liquid such that always only one receiving device (8, 9, 10, 11) is filled with the volume flow of sample liquid available before the next is filled, and effectively simultaneous filling of the receiving devices (8, 9, 10, 11) is prevented. This leads to rapid and complete filling of the respective receiving device (8, 9, 10, 11). Additionally presented is a process with which the regions (K) can be inserted into the distributor channel (7) in a simple manner.
Abstract:
Die Erfindung betrifft ein Bauteil (4) eines Biosensors, mit wenigstens einer ersten Einrichtung (6) zur Aufnahme einer Probenflüssigkeit, wobei die Einrichtung (6) über einen Verteilerkanal (7) mit weiteren Aufnahmeeinrichtungen (8 bis 11) verbunden ist, in die jeweils ein vom Verteilerkanal (7) abzweigender Zulaufkanal (71, 72, 73, 74) mündet und die Zulaufkanäle (71, 72, 73, 74) in Strömungsrichtung (S) der durch den Verteilerkanal (7) weitergeleiteten Probenflüssigkeit aufeinander folgend angeordnet sind. Erfindungsgemäß ist vorgesehen, dass im Verteilerkanal (7) jeweils zwischen zwei in Strömungsrichtung (S) unmittelbar aufeinander folgenden Zulaufkanälen (71, 72; 72, 73; 73, 74) wenigstens ein Bereich (K) zum zumindest zeitweisen Verlangsamen oder Stoppen des kapillaren Flusses der Probenflüssigkeit eingebracht ist. Hierdurch ist es möglich, den kapillaren Fluss der Probenflüssigkeit so zu steuern, dass mit dem zur Verfügung stehenden Volumenstrom an Probenflüssigkeit immer nur jeweils eine Aufnahmeeinrichtung (8, 9, 10, 11) befüllt wird, bevor die nächste befüllt wird und eine quasi gleichzeitige Befüllung der Aufnahmeeinrichtungen (8, 9, 10, 11) verhindert wird. Dies führt zu einer schnellen und vollständigen Befüllung der jeweiligen Aufnahmeeinrichtung (8, 9, 10, 11). Des Weiteren wird ein Verfahren vorgestellt, mit dem auf einfache Weise die Bereiche (K) in den Verteilerkanal (7) eingebracht werden können.

Abstract:
A method for manufacturing an optical microelectromechanical device, includes forming, in a first wafer of semiconductor material having a first surface and a second surface, a suspended mirror structure, a fixed structure surrounding the suspended mirror structure, elastic supporting elements extending between the fixed structure and the suspended mirror structure, and an actuation structure coupled to the suspended mirror structure. The method continues with forming, in a second wafer, a chamber delimited by a bottom wall having a through opening, and bonding the second wafer to the first surface of the first wafer and bonding a third wafer to the second surface of the first wafer so that the chamber overlies the actuation structure, and the through opening is aligned to the suspended mirror structure, thus forming a device composite wafer. The device composite wafer is diced to form an optical microelectromechanical device.
Abstract:
MEMS structure, comprising: a semiconductor body; a cavity buried in the semiconductor body; a membrane suspended on the cavity; and at least one antistiction bump completely contained in the cavity with the function of preventing the side of the membrane internal to the cavity from sticking to the opposite side, which delimits the cavity downwardly.
Abstract:
Crosslinkable random copolymers comprising atom transfer radical polymerization (ATRP) initiators and crosslinked copolymer films formed from the copolymers are provided. The random copolymers, which are polymerized from one or more alkyl halide functional inimers and one or more monomers having a crosslinkable functionality, are characterized by pendant ATRP initiating groups and pendant crosslinkable groups.
