Canadian scientists have published an article in the journal Nature Chemistry stating that they have successfully achieved a molecular "chain reaction" on a physical surface, generating the nano "wires" required for nanocircuits. This study greatly shortens the time currently required to "write" molecular information on specific surfaces, bringing new hope for the realization of nanocircuit manufacturing.
In the field of nanoscience, which is still in its early stages of development, there are currently various ways to "write" information at molecular size on specific physical surfaces. But these methods can only "write" one molecule at a time, so they will all consume a lot of time.
Canadian scientists have achieved for the first time that when a single molecule undergoes a chemical reaction on a surface, it also creates a favorable environment for the next molecule to undergo a chemical reaction. Similarly, molecules randomly placed on this page by researchers will undergo a so-called "chain reaction" to generate a "molecular chain". This molecular chain is the "nanowire" that researchers hope to obtain.
John Polanyi, a professor in the Department of Chemistry at the University of Toronto who led the research, believes that the "nanowire" can enable multiple molecules to self assemble and "write" a complete shape on their own, which is an infinitely long linear shape. This lays the technical foundation for the production of molecular thin "wires" required for nanocircuits.
It is reported that the theoretical basis of this experimental research comes from Ji Wei, associate professor of the Department of Physics of Renmin University of China, who was engaged in postdoctoral research in McGill University, Canada, and proposed the theory of natural growth of molecular chain through calculation. Scientists of the University of Toronto successfully obtained the image evidence of the molecular chain in the laboratory.
