From Guy van Enst
It seems reactive antigens and antibodies can be implanted into what is effectively a microchip, and there are “hundreds” of antigens and antibodies that have potential in this application (10 July, p 19).
Could you also beef up the capacity of computer chips by replacing the binary logic gate with something offering considerably more options than “yes” and “no”? Have I just claimed prior art for the “antigen logic gate”?
