 - Nobility is the measure of potential needed to chemically reduce the material; these were measured against a standard hydrogen electrode.  
 - RMS roughness is a measure of deviation from the mean plane. 
 - Protein was measured in vitro with ellipsometry and step-technique atomic force microscopy, with metal in a dilute plasma solution.
  This is very similar to extracellular fluid, which is suspected to contain the proteins that make first contact with the surface, 
  and form the first adsorbed layer. As stated before this first layer determines the adsorption from then on out.
