We present a multi-functional electroporation method for delivery of biomolecule utilizing a high-density distributed electrode network (HDEN) under tri-phase electric stimulation. The HDEN device, with which drastic pH change during the electroporation was avoided,was demonstrated to be highly effective for transfection of not only DNA plasmids and small interfering RNAs (siRNA), but also a sm...

Electroporation of skin has recently been shown to enhance transport of charged molecules across skin by up to four orders of magnitude. This study demonstrates that high-voltage pulses can also increase transdermal permeation of two neutral model solutes, i.e. mannitol and water, up to 100-fold. The elevated flux results from the persistent increase in skin permeability following electroporati...

We describe for the first time an impulsive, electropulsation-driven backflow in microchannels for on-chip cell electroporation.

A microfluidic electroporation technique is demonstrated based on the operation of an elastomeric valve in a poly(dimethylsiloxane) (PDMS) fabricated microchip and a common dc power supply. The pulse needed for permeabilization of the cell membrane is generated by temporarily interrupting the circuit using the valve. The electropermeabilization of suspended and adherent Chinese hamster ovary ce...

Electroporation is effective in transferring foreign genes into immature neurons in intact brain tissue. We utilized this approach to transfect genes into developing rodent hippocampi. Transfected hippocampi were subsequently dissociated and allowed to differentiate in culture. By optimizing developmental stage of the hippocampus, promoters to drive the marker cDNA, and culture conditions, neur...

Transfection to living chick embryos in ovo by electroporation has been recently developed. In this mini-review, misexpression in brain vesicles is introduced. To transfect, expression plasmid is inserted in the brain vesicle, and the square pulse of 25 V, 50 ms was charged five times. The translation product of the transfected gene is detected 2 h after electroporation, and reaches the peak at...
