摘要: The present invention relates to DNA sequencing with reagent cycling on the wiregrid. The sequencing approach suggested with which allows to use a single fluid with no washing steps. Based on strong optical confinement and of excitation light and of cleavage light, the sequencing reaction can be read-out without washing the surface. Stepwise sequencing is achieved by using nucleotides with optically cleavable blocking moietys. After read-out the built in nucleotide is deblocked by cleavage light through the same substrate. This ensures that only bound nucleotides will be unblocked.

摘要: The invention relates to an apparatus (100) and a method for the processing of single molecules, particularly for the sensing or sequencing of single-stranded DNA. A bottom layer (110) and an electrically conductive top layer (120) with a first and a second slit (111,121), respectively, are disposed on top of each other such that an aperture (A) is formed by the slits. The slits (111,121) are preferably perpendicular to each other. An electrical circuit (140) may be connected to the top layer (120), allowing to sense single molecules that pass through the aperture (A).

摘要: A microfluidic device (100) comprising at least one passive valve (PV, 120, 130), the passive valve being constituted by a sequence of a first carrier layer (CL 1) with an aperture providing a passage (P 1) for fluid flow, a first binding layer (BLI) with a first opening, a flexible layer (FL) with a through-hole (TH), a second binding layer (BL2) with a second opening, and a second carrier layer (CL2). Moreover, the flexible layer (FL) can move within a valve chamber (VC) constituted by the openings. Depending on the pressure difference across the passive valve (PV), the flexible layer (FL) can bend towards the first carrier layer (CLI) and close the aperture, while it opens the passage (P1) when bending in the opposite direction. Two of such properly oriented passive valves together with an intermediate active valve (AV) can constitute a one-stroke pump. A method for manufacturing such a fluidic device is also disclosed.

摘要: The invention refers to a system (100) for affecting a subject and a method for operating the system comprising a medical device like a biopsy gun (130) set in a first state in which it is not able to affect the subject based on a trigger signal or in a second state in which it is able to affect the subject based on the trigger signal, wherein the state is set based on a provided location of the medical device, i.e., for instance, is set based on the distance of the medical device to a target region. The location of the medical device is provided by a location providing unit (140) comprising, for instance, an imaging unit like an ultrasound system (142). Thus, unintended, possible dangerous injuries of the patient are prevented and the safety of the patient during the interventional procedure is increased.

摘要: The invention relates to a biopsy container, a biopsy device, an imaging system, and a method for processing images of a biopsy container. The biopsy container comprises a container orientation mark and an alignment mark. The container orientation mark is configured for a cooperation with a corresponding shaft orientation mark arranged on a tube shaft of a biopsy device to indicate a specific orientation of the biopsy container relative to the tube shaft. The alignment mark is configured for a registration of images of the biopsy container.

摘要: A biopsy device for taking a 3D biopsy may comprise an outer sleeve, a hollow main shaft, a biopsy tube and a tube shaft. The hollow main shaft may have a distal end portion with a sideward facing notch, and the main shaft may be adapted to be accommodated within the outer sleeve. The biopsy tube may be provided for receiving cut and thus isolated tissue. A proximal end of the biopsy tube may be releasably attachable to a distal end of the tube shaft so that the biopsy tube is movable together with the tube shaft within the hollow main shaft between a proximal position in which the biopsy tube is not located in the notch, and a distal position in which the biopsy tube is located in the notch.

摘要: The invention relates to an optical device (110) and a corresponding detection apparatus (100) that may for example be used for monitoring the replication of nucleotide sequences at a surface. In a preferred embodiment, the optical device (110) comprises a waveguide substrate (130) with a wiregrid (140) on a bottom surface (132), wherein apertures (141) of the wiregrid are in at least one direction (x) smaller than a characteristic wavelength (λ) of input light (IL). Moreover, a diffractive structure (120) is disposed on the opposite surface (131) of the substrate (130) for coupling input light (IL) into the substrate (130) such that constructive interference occurs at the apertures (141). Thus evanescent waves can be generated with high efficiency in these apertures, allowing for example for a surface-specific excitation of fluorescence (FL) that can be sensed by a detector (160).
