Control of metal nanoparticles by protein engineering technique
"ACS Nano" (Impact Factor: 13.709), a study on the control of electrical properties of nanobio-materials by controlling multi-dimensional alignment structure of metal nanoparticles through protein engineering technique performed by Prof. Yong-Ho Kim of Nano Science and Technology. It was posted online on the 29th.
The title of the paper is "Peptide-Programmable Nanoparticle Superstructures with Tailored Electrocatalytic Activity". It is a research result that it is possible to control the catalytic activity by dispersing carbon nanotubes which are strong in self-cohesion and hard to disperse by protein design technique and by regulating the size and size of metal nanoparticles to grow specifically.
Conventional carbon nanotubes do not dissolve in organic solvents, and they are difficult to disperse due to aggregation phenomenon that spontaneously gather and are toxic and difficult to use.
Professor Yong Ho Kim synthesized metal nanoparticle-peptide supramolecules. and He confirmed that metal nanoparticles can be formed regularly on nanomaterials by using 3D-Tomography, which is a state-of-the-art technology capable of real-time imaging of a three-dimensional structure.
Professor Yong-Ho Kim said, "The results of this study suggest the possibility of developing electrochemical sensor through nanoparticle-protein self-assembled structure, which is expected to contribute to the development of new nanobiotechnical materials and the development of new conductive protein-based materials."
