Having trouble deflecting charged microparticles in a nanoscale device

  1. Jan 5, 2010 #1
    hey guys
    i am trying to deflect charged microparticles inside a tubed device...
    the device looks like a horizontal Y...
    the microparticle solution in DI water is sent through the base of the Y...and i am trying to deflect them to either one of the two branches at the other end totally...
    i put copper plates at the point where the branches seperate and apply voltage...
    the device is fabricated in PDMS and mounted on glass surface...
    the particles are not deflecting...
    can u guys suggest me what the problem might be?
    furthermore...the supply is enough to deflect the particles as comparing the charge stored in them
