This patent is from Fuji Xerox and teaches a new type of bioelectronic interconnect for nanoscale circuitry. Claim 1 reads:

1. An electrical connection structure comprising

plural carbon nanotubes provided as electrodes, and

a biopolymer,

wherein carbon atoms of graphene sheets of the plural carbon nanotubes and the biopolymer are directly fixed with each other at an arbitrary portion of the biopolymer in a stable electrically connected state

wherein the biopolymer is one of DNA and RNA;

the electrodes are in contact with a portion of the biopolymer, and

wherein the electrodes include Na+ ions diffused inside of the carbon nanotubes.
