I tried tethering with 4.4kb DNA and 1 micron beads. There were hardly any tethers. The most surprising thing I notices that beads were kind of repelled as I moved the trap towards them. My guess; there might be a (not enough NaCl)repulsion between the surface and the beads, and as I move the trap close to the beads the beads starts coming close to the surface and finally repelled before they even fall into the trap.
