Before revision: Femtotechnology is a hypothetical term used in reference to structuring of matter on the scale of a femtometer, which is 10−15 m. This is a smaller scale in comparison with nanotechnology and picotechnologywhich refer to 10− 9 mand 10− 12 mrespectively .
After revision: Femtotechnology is a hypothetical term used in reference to the hypothetical manipulation of matter on the scale of a femtometer, or 10−15 m. This is three orders of magnitude lower than picotechnology, at the scale of 10− 12 m, and nanotechnology, at the scale of 10− 9 m .
