Trapping markers in a ring

Back 

Sample: Kreis2
Beads : Micromod, Sicastar-M plain 1,5µm
Video : 2nd_Test
Area : 80,3 x 96,3µm (250x300+423+333)

A current of 100mA is flowing through both top conducting lines (starting after 12sec). The current is applied perpendicular to each other within the circles.

The markers are collected at three local maxima:

  • Right and left at the inner supply lines
  • At the bottom of the circles.
