Abstract

A new simple transfection method using an integrated electrowetting nano-injector ('INENI') with controlled dosage delivery and high transfection efficiency is disclosed. The volume of delivery can be controlled via voltage application to an inner and outer electrode integrated into a nano-pipette. With higher voltages, more liquid enters the INENI and with lower voltages liquid is expelled. This method can be used to deliver plasmid DNA directly into the nuclei of cells. The INENI requires only the use of a single probe since both electrodes are integrated into the same nano-pipette. Hence, more space is available, and ergo the INENI offers a simplistic means for direct injection of metered amounts of exogenous material into the confines of a cell cytoplasm and/or nucleus while retaining full cell viability.
