Nnaturally occurring biomolecules are used to generate monodisperse nanomaterials where, especially by the use of self-assembling biological structures are used to formfor ordering inorganic materials into one-dimensional metal nano-structures (nanorods and nanowiares)., biotemplating has become a promising mean in bottom-up nanofabrication. The self-assembly of virus-like particles (VLPs) as biotemplates are used to understand the underlying mechanisms governing bottom-up nanofabrication. Genetically engineered Tobaco Mosaic Virus (TMV) and Barley Stripe Mosaic Virus (BSMV) VLPs produced from <i>Escherichia Coli</i>. are served as biotemplates in the synthesis of metal nanorods. The rRecent work has focused on customizing the lengths of BSMV VLPs to meet the multiple applications ranging from electronics, sensing, optics, catalysis and cancer therapy. A hydrothermal solution process in the absence of external reducing agents is performed in the high yield synthesis of more monodisperse/uniform palladium nanomaterials with controllable shapes. The visualization of purified VLPs and the metal coated VLPs via biominerlization are monitored with characterization techniques such as UV-Vis spectroscopy, X-ray absorption spectroscopy and transmission electron spectroscopy. Overall, BSMV VLPs produced from the bacterial expression system is a promising biotemplating candidate with the enhanced stability and the malleability of genetic modification of novel functionalities.
