Abstract
The idea that some functioning bio-surfaces may be built-up using dry (in-vacuum) techniques is interesting because of the compatibility with existing dry-fabrication technologies and that completely novel bio-surfaces not seen in nature may be created. Adsorption chemistry and surface bonding of simple bio-molecules at metal and semiconductor surfaces is probed using synchrotron-based photo-emission techniques. Cysteine, for example, appears to adsorb intact onto Pt{111} in its zwitterionic form. Other examples of in-situ amino-acid and peptide deposition onto metal surfaces are given with a discussion on surface damage due to radiation exposure. © 2005 Australian Institute of Physics
