Indeed, the nanobots in this MIT research are primitive, but the present and future prospects look to be amazing. « The first [component of the aerosol] is a colloid, an extremely tiny insoluble particle or molecule…. The second part of the sensor is a complex circuit containing a chemical detector built from a two-dimensional material, such as graphene. When this detector encounters a certain chemical in its environment, its ability to conduct electricity improves. The circuit also contains a photodiode, a device that can convert ambient light into electric current. This provides all the electricity needed to power the circuit’s data collection and memory. » This is fascinating research, well explained in the link. It will open new doors.
