Eric Drexler may get the credit for popularising the idea of nanotechnology in his books of the 1980s, but chemists have been dreaming of manipulating molecules to do their bidding ever since they found out that all matter is made of atoms. While Drexler’s self-assembling molecular machines may remain a dream, in the last decade chemists have already achieved a more practical version of that dream. Nanoparticles have found use in manufacturing, materials, energy, electronics and medicine. Now, a newly emerging field is using them to do two things at once diagnose and treat diseases.
