Neutralized ion beam modification of cellulose membranes for study of ion charge effect on ion-beam-induced DNA transfer
Low-energy ion beam biotechnology (IBBT) has recently been rapidly developed worldwide. Ion-beam-induced DNA transfer is one of the important applications of IBBT. However, mechanisms involved in this application are not yet well understood. In this study plasma-neutralized ion beam was applied to i...
