A bi-stable quantum wire array of self-assembled nano-medicine and its process present in the invention. The bi-stable quantum wire array with quantum bit and kondo effect is prepared by self-assembling an oxygen radical antagonist of antioxidase, a β-receptor agonist, a P2 receptor agonist, a calcium antagonist of phenyl alkyl amines, and/or a nucleotide monomer of purines and its binary, ternary, quaternary or quinary compounds and using the interaction of inelastic electron tunneling. The invention not only benefits mechanisms-targeted multifunctional device discoveries, but also profits inventions of nanometer structures, novel materials, quantum calculation devices, biosensors and quantum bit magnetic random access memories (MRAM).
