With fancy chemicals being developed for new medicines, a question remains: how can we deliver the most bang for the buck? It would be ideal to have a microscale delivery truck, capable of delivering the drug to the precise location needed. This would also eliminate many side effects experienced through a general delivery of the drug.
Catalytic nanoswimmers are being researched as potential cargo vehicles. They are tiny spheres, with one half coated with a reactive material. This side reacts with chemicals in the environment, and the energy of reaction is transmitted into motion
forward. Attach a blob of drug to them, and they can move medicine. But questions remain about how to get them to go a specific direction, without having to babysit them. Can we make these trucks driverless?
