Abstract
Method and arrangement (10, 20) for preparing samples (15, 27) submergible in a liquid medium. The arrangement includes a carrier structure (11). The carrier includes a device (13, 23) for controllable generation of a magnetic field through influence of a control signal to attract at least part of the at least first and second type of samples (15, 27) towards specific locations on the carrier when connected to a first control signal and to repel at least one of the first or second type of samples when connected to a second control signal.
Claims31
A sample preparing arrangement suitable for enhancing detection of different samples comprising a plurality of samples, said arrangement comprising:
- a carrier structure including a device for controllable generation of a magnetic field through a control signal that controls the device to generate the magnetic field to attract said plurality of samples towards specific locations on said carrier when connected to a first control signal, wherein said samples comprise magnetic particles;
- a controllable releasing force through a second control signal, wherein the controllable releasing force is a force for releasing a known number of the attracted samples;
- and
- a plurality of detection elements, wherein each of said detection elements is integrated in said carrier structure proximal to each of said specific locations, said detection elements enabling detection of localization of said plurality of samples relative to said specific locations.
