| 摘要 |
There is provided a microelectronic sensor device for the detection of target components comprising label-particles, comprising a carrier with a binding surface at which target components can collect; a light source for emitting a light beam incident at the binding surface; a light detector for determining the amount of light in a reflected light beam. In one aspect of the invention, the binding surface is provided by a plurality of aperture defining structures having a smallest in plane aperture dimension (W1) smaller than a diffraction limit, the diffraction limit defined by a medium for containing the target components. Preferentially, the sensor device is used, wherein target components are non-luminescent.
