摘要:
The present invention provides a microf luidic device, for instance for molecular sieving or for detecting a target substance in a sample fluid. The device comprises a first substrate (120) having a substantially flat first surface that is provided with first recesses (124), and a second substrate (128) having a substantially flat second surface that is provided with second recesses (130). At least some of the first recesses are filled with a porous material (114). Alternate first recesses and second recesses form a meandering channel for a sample fluid. The second recesses may be filled with a further porous material. In an embodiment, a capture substance for binding a target substance is arranged in or on the porous material.

This invention provides a biosensor solid or hydrogel substrate comprising one or more temperature indicating agents, each of said one or more temperature indicating agents operating by changing its optical properties and being deposited in and/or at the surface of the biosensor solid or hydrogel substrate as one or more layers and/or spots
摘要:
The invention relates to a substrate material for analyzing one or more fluid samples for the presence, amount or identity of one or more analytes in the samples, whereby the substrate material is adapted in that way that a flow of the sample or parts thereof in and/or with the substrate material is influenced and/or caused by phase transitions, preferably photoinducable phase transitions, in selected areas of the substrate material.
摘要:
The present invention relates to a method for the production of scaffold materials and/or scaffolds for tissue and/or organ engineering, said method comprising the addition of at least one anchoring unit for a labelling agent, to at least one scaffold material and/or to at least one scaffold.
摘要:
A micro system power supply (1) comprises a compartment (7), at least one ion sink void (51, 52) being separated from the compartment (7) by ion pervious separation means (61, 62), a first electrode (41) being arranged in the ion sink void, and a second electrode (42). Such a micro system power supply (1) allows to provide power for a micro system, such as, e.g., an implantable micro device, a MEMS, a bioMEMS, or the like, wherein the micro system power supply (1) can be comparably efficiently manufactured in a manner to be comparably environmentally friendly disposable.
摘要:
To improve automation, especially in 2D gel electrophoresis of proteins, DNA etc., a separation device (1) has a physically activatable means for releasing surfactant, eg. SDS, into the gel fr SDS-PAGE. In one embodiment, surfactant-bound polymer is photolytically cleaved; in another, a barrier layer (30) is melted/destroyed to allow surfactant from reservoir (20) to reach the separation area (10). The barrier layer may comprise a novolac.

The invention relates to a substrate material for analyzing one or more fluid samples for the presence, amount or identity of one or more analytes in the samples, whereby the substrate material is adapted in that way that a flow of the sample or parts thereof in and/or with the substrate material is influenced and/or caused by phase transitions, preferably temperature-inducible phase transitions, in selected areas of the substrate material.
摘要:
The present invention is related to a process for providing an assembly of cell microcarriers, comprising the steps of providing planar, two-dimensional objects having two sides (“flakes”), wherein these objects comprise a material which, upon application of an extrinsic stimulus, is transferred from the planar state into a rolled state, providing cells on one side of said flakes (“cell-bearing side”), transferring the flakes from the planar state into a rolled state (“cell wrap”) by application of said extrinsic stimulus, and coupling at least one type of binding agent to the flakes.
