Abstract

Microencapsulation, i.e. the process of enclosing micron-sized particles of solids or droplets of liquids or gasses in an inert shell which in turn isolates and protects them from the external environ-ment, 1 is one of the main research topics in contemporary chemical research, as shown by the large body of scientific publications and scientific symposia devoted to the subject.* Heterogenization in micron-sized particles is useful for eliminating a processing step and uses more efficiently costly ingredients by enhancing the precision and effectiveness of action through controlled release, or for isolating molecules that would otherwise react with each other.
