Cells get sprayed
Date:1/18/2008

e tip of an extremely fine steel capillary is put under a high voltage. A highly charged drop of water exits the capillary and is atomized into many micro- or nanoscopic droplets. These charged microdroplets are strongly accelerated in an electrical fieldtoward the plate holding the cell culture.

The advantage of this new method: It is suitable for a large variety of cell typesmammalian cell cultures and bacteria, as well as living tissue, as was demonstrated with bird embryos. No cytotoxic reagents that could damage the cells are needed; only pure water or a cell-tolerated saline solution are used. An entire plate of cell cultures can be sprayed bit by bit, or a specific point on some tissue can be targeted. The equipment needed is simple, inexpensive, and portable.
