Abstract
In method of injecting a substance into a living cell having a cell membrane, the substance, the cell and a liquid are placed into a tapering passage. Energy is applied to the cell, thereby inducing poration. To sort cells, a cellular suspension is placed in a tapering passage, including a narrow end that defines an opening that has a dimension corresponding to a cell size. An acoustic wave is applied, thereby forcing cells having a cell size smaller than the selected cell size through the opening, with a portion of the cells having a cell size not smaller than the selected cell size not forced through the opening. To extract material from a cell, an electric field and an acoustic wave are applied, thereby causing the cell membrane to allow the material to pass out of the cell.
