Abstract: |
|||
| This invented technique uses low-energy ion beam to carry on sputtering etching, external gene introduction, and cell fusion, for animal and plant cells which are placed in micro-environmental target chamber and have been cold-pretreated. This invented device consists of an ions source, a chief vacuum chamber allowing the pass through of ion beam, and a micro-environmental target chamber. The latter is provided with smple stand, pre-evacuating system, highly effective filtering material, and gas current purifying structure which interfaces with gas source. An isolating valve connects the chief vacuum chamber with the micro-environmental target chamber. | |||
