|Title:||Low-energy ion beam biotechnology at Chiang Mai University|
|Authors:||L. D. Yu|
Physics and Astronomy
|Abstract:||MeV-ion beam has long been applied to research and applications in biology for many decades as highly energetic ions are undoubtedly able to interact directly with biomolecules to cause biological changes. However, low-energy ion beam at tens of keV and even lower has also been found to have significant biological effects on living materials. The finding has led to applications of ion-beam induced mutation and gene transfer. From the theoretical point of view, the low-energy ion beam effects on biology are difficult to understand since the ion range is so short that the ions can hardly directly interact with the key biological molecules for the changes. This talk introduces interesting aspects of low-energy ion beam biology, including basis of ion beam biotechnology and recent developments achieved in Chiang Mai University in relevant applications such as mutation and gene transfer and investigations on mechanisms involved in the low-energy ion interaction with biological matter such as eV-keV ion beam bombardments of naked DNA and the cell envelopes. © 2009 Materials Research Society.|
