The following graph shows the results from a study in which the adhesion of
  Staphylococcus epidermidis to two different material surfaces was examined. In this study,
  the adhesive coefficient is defined as the percent of the bacteria transported to the
  biomaterial surface that were retained per unit surface area. The surfaces consisted of either
  poly(ethylene) that was coated with plasma proteins or poly(ethylene) with adherent
  platelets. Shear stress was applied to the samples to determine how well the bacteria attached
  to the experimental surfaces. What do these results indicate? How would you apply this
  information if you were to design a cardiovascular implant? (Figure adapted with permission
  from 9.)
 
 
  What will be an ideal response?
