1. A method of coating a surface, comprising sequentially depositing on a surface, under pH-controlled conditions, alternating layers of polymers to provide a coated surface, wherein a first polymer is selected from the group consisting of pH dependent cationic polyelectrolytes and neutral polymers, and a second polymer is selected from the group consisting of anionic polyelectrolytes, thereby preventing or permitting cell adhesion to said coated surface.
