- PublikationA new electrospray method for targeted gene delivery(Nature, 03/2018) Boehringer, Stephan; Ruzgys, Paulius; Tamò, Luca; Satkauskas, Saulius; Geiser, Thomas; Gazdhar, Amiq; Hradetzky, David [in: Scientific Reports]A challenge for gene therapy is absence of safe and efficient local delivery of therapeutic genetic material. An efficient and reproducible physical method of electrospray for localized and targeted gene delivery is presented. Electrospray works on the principle of coulombs repulsion, under influence of electric field the liquid carrying genetic material is dispersed into micro droplets and is accelerated towards the targeted tissue, acting as a counter electrode. The accelerated droplets penetrate the targeted cells thus facilitating the transfer of genetic material into the cell. The work described here presents the principle of electrospray for gene delivery, the basic instrument design, and the various optimized parameters to enhance gene transfer in vitro. We estimate a transfection efficiency of up to 60% was achieved. We describe an efficient gene transfer method and a potential electrospray-mediated gene transfer mechanism.01A - Beitrag in wissenschaftlicher Zeitschrift
