摘要:
The invention concerns a method and an apparatus for generation of micropartides containing an immobilized functional component, where the following measures are proposed: —spraying a liquid (32) containing a soluble alginate and a functional component consisting of molecules or nanoparticles to generate a stream (60) of droplets, —directing the stream (60) of droplets onto a precipitation bath (16) and capturing the droplets therein by application of high voltage (14), —precipitating the droplets in the precipitation bath (16) by means of a precipitation liquid (18) containing an alginate complexing agent, such that the droplets are solidified to form micropartides (10) containing the functional component and —extracting the micropartides (10) from the precipitation bath (16).

The invention relates to a disposable diagnostic part with a puncturing element (14), which is constructed for puncturing the skin (26) and has a collecting tubule (16) for taking up body fluid, and a detecting element (18), which has a test layer (42) provided with reagents for the detection of an analyte in the body fluid and is disposed in the collecting tubule (16). In order to ensure an improved stability and biocompatibility, it is proposed that the detecting element (18) be provided with a sealing layer (20), which is applied on the test layer (42) and covers the reagents.
摘要:
Body fluid sampling device comprising a skin-piercing element (1) having a collection zone (9) for receiving body fluid, and the device further comprising a fluid receiving means (10) remote spaced apart from said collection zone so that body fluid in said collection zone will not contact the fluid receiving means initially. Said collection zone takes up a very small volume of body fluid of about 10 to 500 nl in a very short time period of less than 0,5 s. Said fluid receiving means may have a test zone for performing an analytical reaction. Fluid sample from said collection zone is automatically or manually transported to said fluid receiving means to contact said fluid with said test zone.

The present invention relates to an analytical testing element comprising a surface designed as a chemical verification layer (14) and a spreading net (16) disposed thereon for the planar distribution of a liquid sample, wherein the spreading net has a filament structure. According to the invention, the spreading net (16) comprises an oxidized metallic layer (20) at least at the surface of the net facing the verification layer (14).

Disclosed is a device that is to be introduced into a body and comprises a distal region which is provided with a tip zone for creating an opening in the skin, and a segmented area which encompasses at least two subareas. Said subareas are connected at least to one another and to the distal region in an essentially rigid manner in a rigid state while being movable towards each other in a flexible state. Also disclosed is a system in which a sensor is integrated into the inventive device that is to be introduced into a body.
摘要:
The invention relates to a diagnostic test strip for liquid samples comprising a flexible conveyor strip (12) and a plurality of test fields (14) attached to the conveyor strip (12) so as to be distributed in the longitudinal direction of the strip, wherein the test fields comprise a detection layer (18) and a spreading net covering the detection layer (18) for accommodating liquid samples over the area thereof, wherein the spreading net is composed of a grid-like woven fabric (20) having woven-fabric threads (28, 30) that cross at right angles. In order to avoid bulging of the woven fabric under strip tension, it is proposed that the woven fabric (20) be oriented at an angle to the conveyor strip (12) so that all woven-fabric threads (28, 30) extend at an angle to the longitudinal direction of the strip.
