Abstract
The invention refers to a new process for preparing coated particles and hollow shells by coating colloidal particles with alternating layers of oppositely charged nanoparticles and polyelectrolytes and optionally removing the colloidal cores.
Claims26
A process for preparing coated particles comprising the steps:
- (a) providing template particles and
- (b) coating said template particles with a multilayer comprising (i) alternating layers of oppositely charged nanoparticles and polyelectrolytes and/or (ii) alternating layers of oppositely charged nanoparticles.
A coated particle having a core which is a template particle and a multilayer shell comprising a member selected from the group consisting of alternating layers of (i) oppositely charged nanoparticles and polyelectrolytes, and (ii) oppositely charged nanoparticles.
