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\n-	Wall thickness and co
 mposition\n-	Multiple components and variation along the normal\n\nConsequ
 ently these capsules offer the control of the permeability along the norma
 l via pH\, salt\, temperature\, light\, ultrasound\, or microwaves. They t
 herefore promise applica-tions in many areas making use of controlled rele
 ase. Examples on this will be given by means of drug delivery and remote c
 ontrolled release inside cells and of triggering of chemical reactions in 
 enzyme chemistry. The latter can be induced via multicompartment capsules 
 or via fusion of capsules containing different reactands.\n
