Molecular organic biology _is_ already since the dawn of time the realization of nanobots through enzymes and various automata built in chemistry. I think (to your point) what is interesting is adding new chemical nanobot-esque compounds that nature had not yet developed. For example that can coordinate with external focused energy.
