摘要:
An electrotransport device for transdermal drug delivery has a number of electrodes and driving circuitry for supplying driving signals to the number of electrodes. The electrodes are connected to the driving circuitry in rows and columns. The driving circuitry has row driving circuitry for supplying a row signal to a row of electrodes, and column driving circuitry for supplying a column signal to a column of electrodes. A predetermined electrode is individually addressable by supplying a row signal to a corresponding row of electrodes and a column signal to a corresponding column of electrodes.

摘要:
A radiation detection system (100) is described comprising a measurement region (104) in a measurement chamber adapted for receiving at least one sample (108) to be examined and adapted for receiving excitation radiation for impingement on the at least one sample (108) and for generating sample radiation. The radiation detection system (100) furthermore comprises at least one detector element (106) for detection of the generated sample radiation. The radiation detection system thereby is a front irradiation system, i.e. the excitation radiation is incident on a first side of the measurement region (104) in a measurement chamber and the at least one detector element (106) is positioned at a second side of the measurement region (104) in a measurement chamber, the second side being opposite to the first side with respect to the measurement region (104) in a measurement chamber, such that detection occurs at the side facing the first side. The detection system (100) also comprises optical means (112) adapted for guiding said excitation radiation aside the at least one detector element (106).

The invention relates to a microelectronic sensor device and a method for the investigation of biological target substances (20), for example oligonucleotides like DNA fragments. In one embodiment, the device comprises a reaction surface (RS) to which target specific reactants (10) are attached and which lies between a sample chamber (SC) and an array of selectively controllable heating elements (HE). The temperature profile in the sample chamber (SC) can be controlled as desired to provide for example conditions for a PCR and/or for a controlled melting of hybridizations. The reactant (10) and/or the target substance (20) comprises a label (12) with an observable property, like fluorescence, that changes if the target substance (20) is bound to the reactant (10), said property being detected by an array of sensor elements, for example photosensors (SE). The fluorescence of the label (12) may preferably be transferred by FRET to a different fluorescent label (22) or quenched if the target substance (20) is bound.
