History of Nanotechnology
E = mc2 Atomic bomb Biotechnology/Genetic Engineering Quantum Physics Nanophase materials
6
Nanotechnology Past and Present
(A) a hand holding a computer chip. (B) computer chip (C) living cell placed on the chip (D) two nanocomputers beside the cell. (E) shows an irregular protein from the cell on the lower right, and a cylindrical gear made by molecular manufacturing at top left. (F) shows two atoms in the protein, (G) reveals the nucleus of the atom as a tiny speck. Below: 35 xenon atoms spell out a familiar logo
