WebIon-beam sculpting at nanometre length scales. Nature 412(6843): 166-169. Abstract Manipulating matter at the nanometre scale is important for many electronic, chemical and biological advances, but present solid-state fabrication methods do not reproducibly achieve dimensional control at the nanometre scale. WebCells employ proteins to perform metabolic functions and maintain active physiological state through charge transfer and energy conversion. These processes are carried out in a narrow space precisely and rapidly, which, no doubt, bring great difficulty for …
