(536b) Green Synthesis of Palladium Nanomaterials Via Biological Templates Using Tmv and Bsmv Virus-like Particles with Enhanced Stability and Customized Dimensions

In recent years, there has been increased interest in the use of naturally occurring biomolecules as biotemplates in the fabrication of nanomaterials. The use of the self-assembly biological structures forms one-dimensional metal nanorods and nanowires with monodisperse structures. The virus-like particles (VLPs), which are the self-assembly of virus particles, of Tobacco Mosaic Virus (TMV) and Barley Stripe Mosaic Virus (BSMV) serve as biotemplates to understand the direct synthesis of palladium nanomaterials. The TMV, BSMV VLPs and their engineered variants are produced from bacterial Escherichia Coli system. Our recent work has focused on the stability control and the length customization of BSMV VLPs in order to expand the diverse industrial applications, such as sensing, catalysis, electronics and medical therapy. The optimization of VLP protein extraction and purification process are investigated to be compared to plant virus particles. More uniform palladium nanorods with controllable shapes are synthesized via biomineralization using hydrothermal process in the absence of external reducing agents. The VLPs are characterized with transmission electron spectroscopy, X-ray absorption spectroscopy and energy dispersive X-ray spectrometry to provide the insights into the mineralization process. Briefly, biotemplating using BSMV VLPs expressed from E. Coli. which has the genetic modification malleability, various lengths and enhanced stability to generate controllable monodisperse metal nanomaterials is promising in the bottom-up nanotechnology.
