In a method of injecting a substance into a living cell, the substance, the cell and a liquid are placed into a tapering passage (312). Energy is applied, thereby inducing poration. To sort cells, a cellular suspension is placed in a tapering passage (312), including a narrow end that defines an opening (314) that has a dimension corresponding to a cell size. An acoustic wave is applied by a transducer (330), thereby forcing cells having a cell size smaller than the selected cell size through the opening (312). To extract material from a cell, an electric field, formed between a first electrode (320) and a second electrode (322), and an acoustic wave are applied, thereby causing the cell membrane to allow the material to pass out of the cell. |
