In recent over ten years, owing to the mutual permeation and the coexperiments of biologists and physicists, a new field of biophysical technology was born and has grown up. It not only involves the basic study of cell electromagnetic effect and its mechanism, but also, as a new field in biotechnology, it relates to the wide application of many other fields, such as molecular biology, cellular biology, immunology, medicine, food and agriculture. The newest progresses in this field are summarized.
