Disclosed is a method of preparing a sensor for the analysis of a sample fluid, said sample fluid containing one or more target molecules. The method comprises the step of introducing said sample fluid into a chamber equipped with a porous substrate, one or more probe molecules being applied to said porous substrate and said probes being able to specifically bind to said one or more target molecules. The method further comprises the step of moving said substrate and said chamber relatively to each other in order to force said sample fluid through the pores of said porous substrate and to capture the one or more target molecules with the one or more probe molecules. Also disclosed is a sensor for the analysis of a sample fluid.

The present invention provides a reaction vessel (20) for a PCR device. The reaction vessel (20) comprises a sample vial (32) defining a reaction chamber (33) for performing PCR and a storage vessel (62) defining a storage chamber (63) for optical detection. The reaction chamber (33) is in fluid communication with a liquid supply port (34) for supplying a liquid sample containing at least one target DNA to the reaction chamber (33). The reaction chamber (33) and the storage chamber (63) are in fluid communication via a spacer element (42) and a porous membrane (51) for hybridization of the at least one target DNA within the liquid sample onto specific immobilised hybridization probes. The lower end of the spacer element (42) extends into the reaction chamber (33), but does not reach the bottom thereof. The upper end of the spacer element (42) is located in proximity of the porous membrane (51), which is made from a material having different physical properties in a dry state and a wet state. In the dry state the porous membrane (51) allows air as well as liquid to pass therethrough. In the wet state the porous membrane (51) still allows the passage of liquid therethrough, but not of air, such that during a PCR the liquid sample remains in the reaction chamber (33) and after the PCR the reaction vessel (20) is configured to force the liquid sample via the spacer element (42) to the porous membrane (51) for hybridization and detection of the at least one target DNA in the liquid sample. Moreover, a PCR device comprising such a reaction vessel (20) as well as a method for performing PCR are described.
摘要:
A patient presses a finger concurrently against a needle (14) of a collection container (12) and a fingerprint surface (22, 52). In one embodiment, the patient's fingerprint is read electronically by a scanner (24) and correlated with a container serial number (16). In another embodiment, the patient's fingerprint is embossed in a foil layer (52). An analyzer assembly (40, 40′ 40″) analyzes the biological sample and reads either the container serial number or scans the fingerprint carrying layer (52) and sends the test results and either the fingerprint or container identification to a patient memory (30). Using the fingerprint information, a processor (32) correlates the test results with a record (60) of a corresponding patient. Alternately or additionally, the analyzer assembly includes a DNA analyzer (70) which measures preselected DNA characteristics (76) of the sample. The processor (32) compares the measured DNA subset characteristics with DNA subset characteristics (66) in the patient records to correlate or confirm the correlation of the analysis results with the proper patient.

The actuator can be formed of LC material in an elastomeric network. The detector (30) can be optical, magnetic or capacitive. The actuator can be arranged as a layer and the deformation be a curling of the layer.
摘要:
Determining the fetal heart rate comprises irradiating an ultrasound beam in the direction of the fetal heart. The moving parts of the fetal heart cause a Doppler shift which is used to determine the fetal heart rate via an autocorrelation function. Moving parts of the fetal heart with different velocities and Doppler shifts originating from other physiological sources generate secondary maxima in the autocorrelation function, so that an accurate heart rate determination becomes nearly impossible. This problem is overcome by parallel processing of the demodulated ultrasound signal in various pass-bands, for which purpose the signal is fed to filters (28, 30) of different frequency characteristics. The output of the pass band with the better result is used for fetal heart rate circulation.
