Although nano/microfabrication techniques are rapidly advancing it remains a challenge to fabricate separate individual nanoscale structures and actuators en masse. A possible resource for fabricating such tiny elements exists within microorganisms. Specifically, bacteria produce an assortment of objects from polymeric biomolecules. This talk will discuss the practical integration of biomolecular motors for biologically powered microfluidic systems as well as the development of polymeric protein nanostructures such as bacterial flagellar filaments for use in micro and nanoscale devices. Bacterial flagellar propulsion represents an extraordinary system in nature for generating motion at the small scale. Due to their unique molecular polymeric structure can adopt different shapes, depending on the local chemical and flow conditions. Their motion induces a local flow that can be used to propel cells, as well as much larger structures through a fluid environment. The control of microbots powered by bacterial teamsters will be highlighted through the talk. The use of biological nanostructures in engineered systems represents a critical step toward understanding both how the biological world has evolved at the nanoscale as well as how scientists and engineers can mimic and improve on nature using modern fabrication and assembly. In addition to the bacterial actuation and transport at micro/nanoscales, the possibility of using nanopore technology and synthesis of gold nanorods will be introduced to detect and configure bacteria/viruses in water for the identification of certain types of pathogens.
