Nanotechnology involves the creation and manipulation of complex structures on the scale of nanometers— something organisms have done for about 3.8 billion years. Using DNA, RNA, and a huge variety of proteins, living cells build complex molecules and nanoscale organelles, and create nonliving materials, such as tooth enamel, with nanoscale structures. So it is logical for nanotechnologists to seek to duplicate organisms’ own techniques to try to create new nanomachines from the bottom up.
