Abstract:
A microfluidic bead-packing method includes activating a first micropump to transfer active microbeads through an inlet microchannel from a bead suspension reservoir to an adsorbing channel; packing the microbeads in the adsorbing channel; and activating a second micropump to reverse flow through at least a portion of the inlet microchannel and to transfer a sample fluid through the inlet microchannel from a sample reservoir to the adsorbing channel such that the sample fluid interacts with the packed microbeads.
Abstract:
A microfluidic device in which a first substrate and a second substrate are joined via an adhesive layer, and in which a first fluidic channel and a second fluidic channel are formed between the first substrate and the second substrate, including a communication-reducing portion configured to reduce communication of air bubbles in the adhesive layer disposed in a region between the first fluidic channel and the second fluidic channel, wherein the communication-reducing portion includes a first region in which the adhesive layer is thinner than in peripheral regions due to existence of a projecting portion included in the first substrate, and a second region disposed next to the first region, in which the adhesive layer has lower density than in peripheral regions due to existence of a recessed portion or a through hole included in at least one of the first substrate and the second substrate.
Abstract:
The invention relates to a microfluidic component made of a metal sheet having a structure which comprises a closed fluid line and which is formed of a structured surface of a first section of the metal sheet and an adjoining structured or unstructured surface of a second section of the metal sheet, wherein the metal sheet is folded such that the sections integrally connected to each other are located on top of each other in a surface-parallel manner. The metal sheet further comprises at least one third section having a contoured edge and is moreover folded such that the third section is also supported in a surface-parallel manner and the contoured edge forms a first wall section and the adjoining structured or unstructured surface of the first or second section forms a second wall section of an open fluid line. The invention further relates to a microfluidic reactor comprising a plurality of such microfluidic components and to a method for producing such components.
Abstract:
Microfluidic devices having wall structures comprised of sintered glass frit and further including a glass, glass-ceramic or ceramic membrane structure sealed by a sintered seal to said wall structures, such that a a fluid passage or chamber is defined at least in part by the wall structures and said membrane structure. This allows for changes in pressure within the fluid passage or chamber to cause deflections of the membrane structure, providing for direct measurement of pressure within the device. The microfluidic device may have both floors and walls of sintered frit, or may have only walls of sintered frit, with planar floor-like substrate structures, thicker than the membrane structure defining the vertical boundaries of the internal passages. The device may include multiple fluid passages or chambers each defined at least in part by a membrane structure. Multiple membrane structures may be used in a single device, and one single membrane structure may be used for multiple passages or chamber.
Abstract:
The present invention provides a process for producing a stamp for hot embossing (HE). The stamp can be constructed from any photo-resist epoxy that is stable at temperatures equal to the glass transition temperature (T g ) of the material to be stamped. The stamp can be used repeatedly without significant distortion of features. The stamp benefits from low relative cost, high fidelity of features in all three-dimensions and fast construction. The process for producing a stamp for hot embossing from a resist, comprising the steps of producing a seed layer L1 from a selected photoresist polymer material, soft baking the seed layer L1, exposing said seed layer L1 to initiate cross-linking and then post-exposure bake L1 to fully cross-link it, coating the cross-linked seed layer L1 with a second photoresist polymer layer L2; soft baking the second photoresist polymer layer L2; applying a mask to the top surface of the soft baked layer L2 and illuminating the unmasked portions of the soft baked layer L2 with UV radiation through the mask, wherein the exposed areas form the pattern of the embossing features, washing away un-exposed regions of the photoresist with a developer to leave behind a relief pattern formed in the second photoresist polymer layer L2, which relief pattern corresponds to a pattern in the mask.
