Abstract:
1. A microfluidic target sampler comprising: a microfluidic chip comprising a substantially circular area; a conveyor adapted to convey collected targets to the microfluidic chip; a pair of filters adapted to confine microbeads from a solution within the microfluidic chip; a capture area in the substantially circular area and independent of the pair of filters; an immunoassay stack in the capture area, configured to be completed by presence of the targets, thereby enabling capture of the microbeads exclusively in the presence of the targets; electrodes connected with the capture area, the electrodes adapted to measure a change of the capture area dependent on an amount of captured microbeads thus detecting the capture of the microbeads; and a circulator connected to the substantially circular area and configured to continuously circulate the microbeads in the substantially circular area.
