    • The invention relates to a microelectronic sensor device for manipulating a sample in an exchangeable carrier (111), for example for optically detecting target particles (1) in a sample liquid that is provided in a sample chamber (2) of the carrier (111). The microelectronic sensor device comprises a number of n>1 magnetic field generators (141-143), e.g. electromagnetic coils, with which magnetic fields can be generated in a target region (110). A control unit (150) is provided that can determine and evaluate the mutual coupling or the self-inductance of the magnetic field generators and/or signals from magnetic field sensors attached to the carrier with respect to the presence and/or state of a carrier (111) in the target region (110). In this way, the control unit (150) can for example detect if the carrier (111) is correctly positioned in the sensor device and/or where a magnetically interactive substance (1, 120) is located.
    • 本发明涉及一种用于操纵可交换载体(111)中的样品的微电子传感器装置,例如用于光学检测设置在载体(111)的样品室(2)中的样品液体中的目标颗粒(1) 。 微电子传感器装置包括多个n≥1个磁场发生器(141-143),例如, 电磁线圈,可以在目标区域(110)中产生磁场。 提供控制单元(150),其可以相对于载体的存在和/或状态来确定和评估附接到载体的磁场传感器的磁场发生器和/或信号的相互耦合或自感 (111)在目标区域(110)中。 以这种方式,控制单元(150)可以例如检测载体(111)是否被正确地定位在传感器装置中和/或磁性交互物质(1,120)所在的位置。
