1. The wavelike properties of electrons inside matter are influenced by variations on the nanometer scale. 2. The systematic organization of matter on the nanometer length scale is a key feature of biological systems. 3. Nanoscale components have very high surface areas. 4. The finite size of material entities, determine an increase of the relative importance of surface tension and local electromagnetic effects. 5. The interaction wavelength scales of various external wave phenomena become comparable to the material entity size.

Proteins that form nanoscopic aqueous tunnels in cell membrane Enormous range of Biological functions - regulate ion flow and composition inside cell - control electrical signaling in the nervous system - muscle contraction, drug delivery – Disease malfunctioning channels

IRA A. Fulton School of Engineering Arizona Institute for Nano-Electronics So, why are we interested in ion channels ??

– Channels are naturally occurring device elements – Nanoscale devices with ~0.2-15nm in diameter and between 0.3-10nm length – self-assembled – perfectly reproducible – have many specific built-in features and functions – can be mutated – Channels can be designed with specific conductances, selectivities and functions
