Just for reference, you should know that the more-or-less minimum feature size for a biological structure is about 100 nm: https://en.wikipedia.org/wiki/DNA#/media/File:DNA_nanostruct...

that's only about 100x smaller than contemporary transistor features, so realistically there is a upper limit to the energy benefit of biocomputing structures which is about 10,000x, based on energy typically scales with size squared.
