My love for the invisible led me to study the nanoscale world where I turned viruses into nanomaterials. When it comes to design, biology is a master, so why not use what it has already built? Viruses are symmetric nano-sized cages that assembly on their own and protect what's inside them. I built these nano-cages derived from viruses around enzymes (nature's catalysts) to create nano-reactors. The enzymes made a biofuel that maybe someday could be efficient enough to decrease fossil fuel use.
