(a) Entrapment of 100 nm fluorescently-tagged liposomes suspeneded in the PBS solution using a 1 μm pipette and 10 V/cm applied E-field. (i) The results after 100 seconds of applied positive bias at the base. (ii) The results after 100 seconds of applied negative bias at the base. (b) Selective entrapment of 100 nm flourescently-tagged liposomes and 510 nm non-fluorescent COOH-PS beads suspended in the PBS solution. (i) The results after 100 seconds of applied negative bias at the base of the pipette. (ii) The results after 100 seconds of the voltage polarity reversal to positive bias at the base. (c) Selective entrapment of 100 nm fluorescently-tagged liposomes and 510 nm non-fluorescent COOH-PS beads suspended in PBS solution. (i) The results after 100 seconds of applied positive bias at the base of the pipette. (ii) The results after 100 seconds of the voltage polarity reversal to negative bias at the base.
