The Institute of Plasma Physics, under the Chinese Academy of Sciences, has recently rolled out a single ion beam based irradiation device for accurate cell positioning. The single ion beam irradiation based accurate cell positioning technology is able to shot ions to the prescribed cell positions one by one, making it a desirable solution to positioning micro targets and accurate irradiating particles in a quantitative manner.

It is believed that the successful development of the device marks an important progress achieved in China?¯s ion beam irradiation technology, facilitating research activities in the fields of radioactive biophysics, cell signal transmission, genetic expression control, and developmental biology. In addition, a low-energy ion beam based cell-repairing technology and associated device, developed along with the efforts, have become a basic methodology and classic device for future innovative studies. In 2003, the Chinese State Intellectual Property Office and the World Intellectual Property Organization jointly honored the finding ?°Gold Award for China Invention?±. The technology and associated device have found extensive applications in microbe studies and plant species breeding. During the 10^th Five-year Plan period(2001-2005), the device has technically been upgraded to a smaller and more practical one for an annual production capacity of 10 to 15 units. The device has been installed respectively at the labs in Xinjiang, Inner Mongolia, Anhui, Jiangsu, Zhejiang and other places. The Institute, in collaboration with Xinjiang and Inner Mongolia scientists, also established ion beam breeding device application and demonstration center in two autonomous regions, making its due to the diffusion of ion beam biotechnology to the west region.
