Abstract

<p>Non-lithographic fabrications of devices such as electronics and sensor have been studied extensively by assembling nanometer-sized building blocks into the device configurations. We have been functionalizing biological nanotubes by metal and semiconductor nanocrystals and assembling them to devices for photonics, electronics, and sensor applications. By using peptides and proteins on the nanotubes as templates, peptide nanotubes with a variety of electric properties can be grown by coating them with various metals/semiconductors via their mineralization function. In addition, peptides’ molecular recognition functions enable one to add functionalities to various positions on the nanotubes (e.g., inside, outside, edges) or anchor them to desired places on device substrates such as integrated circuits. Over all, these features provide peptide nanotubes multi-functionality, and they can be applied to build complex geometries of nanoscale devices.</p>
