DESCRIPTION:The versatile technique of preparing multilayers by consecutiv
 e alternating adsorption of oppositely charged polyelectrolytes can be ada
 pted to coat sacrificial colloidal sub-strates. This enables fabrication o
 f capsules with well-defined:\n\n- Size and shape - Wall thickness and com
 position - Multiple components and variation along the normal\n\nConsequen
 tly these capsules offer the control of the permeability along the normal 
 via pH\, salt\, temperature\, light\, ultrasound\, or microwaves. They the
 refore promise applica-tions in many areas making use of controlled releas
 e. Examples on this will be given by means of drug delivery and remote con
 trolled release inside cells and of triggering of chemical reactions in en
 zyme chemistry. The latter can be induced via multicompartment capsules or
  via fusion of capsules containing different reactands.
