  • Abstract
    We report three improvements towards the handling of biological liquids, using the so-called liquid-dielectrophoresis technique (L-DEP). Firstly we actuated liquids with 10mS/m conductivity (i.e. 10 times larger than literature). Secondly we lowered the actuation voltage down to 100Vpp (i.e. about 3 times lower than literature). Thirdly we could reach up to 15 successive actuations before device breakdown.
