Beats Array Counter Sensor The scheme of specific (a) and non- specific (b) reactions is shown. Lower part of the figure consists the microphotographs of the particles on the supporting-plate and the calculated surface concentration of the beads. The scheme of specific (a) and non- specific (b) reactions with magnet elimination of non-specific reaction is shown. Lower part of the figure consists the microphotographs of the particles on the supporting-plate and the calculated surface concentration of the beads. a a b b. Ratio of signal: noise achieved 4:1. Magnetic field allowed improving it up to 8:1
