▣ Abstract : 
Making nanocomposites from combinations of materials each with their own unique functional advantage can often solve issues that cannot be addressed when utilizing only one type of materials. Therefore, controlling nanostructure and nanoarchitecture have become central issues in energy devices such as high-power rechargeable batteries and highly efficient solar cells whose performance requires several different material properties. Biological systems can provide precise control over materials interaction between peptides and other non-biological materials through biological molecular recognition, and the capability of modifying and controlling materials interaction through genetic engineering provides an attractive route to creating new nano-structured hybrid materials systems. In this talk, new approaches to effectively incorporating single-walled carbon nanotubes (SWNTs) into nanostructures will be presented. Genetically engineered M13 virus clones are developed to assemble SWNTs and technically important inorganic materials biomineralized on the protein surfaces of M13 virus to create hybrid nanostructured electrodes for high-power Li-ion batteries and highly efficient dye-sensitized solar cells. The fundamental understanding and new approaches this work presents will provide new insight into designing materials for high performance energy devices.
