  • Publication number: 20140077315
    Abstract: An electronic sensor apparatus for detecting chemical or biological species includes a semiconductor chip, a sensor device, and a substrate. The chip is produced from a semiconductor substrate and is configured for one or more functions such as: amplifying and/or evaluating an electrical voltage, amplifying and/or evaluating an electric current, amplifying and/or evaluating an electrical charge, and amplifying and/or reading out capacitance changes. The sensor device has an active surface configured to detect chemical or biological species and generate an electrical signal based on a species-characteristic interaction with the active surface. The electrical signal can be an electrical voltage, an electric current, an electrical charge and/or a capacitance change. The substrate is produced from a melt-moldable material and has a surface including first and second regions. The chip is at least partly embedded in the first region, and the sensor device is at least partly embedded in the second region.

  • Publication number: 20130175213
    Abstract: A system for separating bodily fluid constituents is disclosed. The system includes a first substrate which, in a first main surface, has a first cavity for holding a bodily fluid sample, a second substrate, which, in a first main surface facing the first substrate, has a second cavity) for holding constituents separated from the bodily fluid sample, which second cavity lies opposite to the first cavity, a filter layer, which is arranged between the first substrate and the second substrate and which is designed to separate constituents of the bodily fluid sample in the first cavity and to pass the separated constituents to the second cavity, and a first thermoplastic connection layer, which is arranged between the first substrate and the filter layer, interconnects the first main surface of the first substrate and the filter layer in a fluid-tight manner and has a cutout lying opposite to the first cavity.

  • Publication number: 20130008511
    Abstract: A microfluidic device includes a first supply channel and a first discharge channel fluidically connected to one another by a first valve. The device also includes a second supply channel and a second discharge channel fluidically connected to one another by a second valve. At least one of the first channels can be fluidically connected to at least one of the second channels by a T-valve. The device also includes a control unit for controlling the valves, the control unit being configured in such a way that a first fluid from one of the first channels and a second fluid in one of the second channels can be laminated in parallel by actuating the valves in one of the first or second channels. A microfluidic system and a method for transporting fluids, and a use thereof are also disclosed.

  • Publication number: 20120276592
    Abstract: A microfluidic system for a polymerase chain reaction is disclosed. The system includes a substrate having three chambers fluidically connected to one another in series, which chambers are held at different temperature levels. An elastic film on the substrate closes the chambers, wherein the chambers connected to one another in series are fluidically closable at the ends of the serial connection. The film above a chamber is movable into the chamber for emptying of the chamber. Thus, without a separate pump, it is possible for a PCR solution to be pumped through the chambers or temperature levels, with the PCR solution in a chamber acquiring the temperature thereof very rapidly.

  • Publication number: 20110306930
    Abstract: A hypodermic needle, particularly for injecting a pharmaceutical substance into a human or animal body is disclosed. The needle provides a simple way of improving long-term use in a human or animal body. The hypodermic needle includes a tubular hollow body having a needle tip for introducing the hypodermic needle into the human or animal body, wherein the hollow body has a rigidity which is reducible by the influence of heat and/or moisture.
