Murphy, Copyright 2001 by Wiley-Liss, Inc, ISBN 047125391X: Viruses: 100 nm to 10 nm Proteins: 10 nm to slightly more than 1 nm Amino Acids: somewhere around 1 nm Atoms: 0.1 nm typical Wavelengths: Ultraviolet: Roughly 10 nm to 100 nm [rounded] Gamma and X rays: 0.1 nm to 10 nm Electron microscopes resolution limit: 0.1 nm Summary: 6nm is smaller than a virus but comparable to the size of a protein molecule.
