✦ Synopsis

A new model for the influence of non-equilibrium impurity adsorption on the collective behaviour of growth steps is presented . It is shown to lead to a dynamical coupling of step motion . Under quite general conditions this leads to a macrostep height increasing proportional to ln(time) . Predictions for and comparisons with experiments are indicated .

## Abstract The adsorption kinetics of human serum albumin (HSA) on CH~3~‐ and COOH‐terminated self‐assembled monolayers (SAMs) has been investigated using radioassays and atomic force microscopy (AFM). On both surfaces, the amount of HSA adsorbed reached a plateau after 30 min. The plateau level w
