    摘要: The invention relates to a microelectronic sensor device for the examination of target particles (1) that are bound to binding sites (3) at the binding surface (12) of a carrier (11). In a preferred embodiment, an input light beam (L1) is transmitted into the carrier (11), where a frustrated total internal reflection (FTIR) takes place at the binding surface (12). The amount of light in a resulting output light beam (L2) is detected by a light detector (31) and provides information about the presence of target particles at the binding surface. Moreover, an actuation unit (50) induces movements of the bound target particles (1) by an interaction with a magnetic field (B) or an electric field, particularly with a given modulation frequency (COIn), such that by a demodulation of the detector signal (S) effects of the target particles can be distinguished from background.

    摘要: The present invention provides an FTIR system comprising a first light source emitting light of a first wavelength, a sample volume with an adjacent sensor surface, a detector for detecting light reflected at said sensor surface. The sensor surface is illuminated by said first light source fulfilling the condition of total internal reflection and generating an evanescent field with a decay length within the sample volume. The system further comprises means for changing the decay length of the evanescent field and means for correlating the detected signals with the change of the decay length of the evanescent field.

    摘要: A magnetic sensor device is disclosed for the detection or determination of a magnetic field, such as for example, but not limited to, the presence of magnetic particles (15). In particular it relates to an integrated or on-chip magnetic sensor element (11) for the detection of magnetic nano-particles functioning as a label to biological molecules. The device of the present invention offers reduced cross-talk between the magnetic sensor element (11) and a magnetic field generator (12) by compensating capacitive and/or magnetic coupling for instance by using an electrostatic shield and/or modulation and demodulation techniques. The device may be used for magnetic detection of binding of biological molecules on a micro-array or biochip.
