From molecules to systems: sol-gel micro-encapsulation in silica based materials.

by Rosaria Ciriminna, Marzia Sciortino, Giuseppe Alonzo, Aster de Schrijver, and Mario Pagliaro.
Chemical Reviews 2011, 111, 765–789


This paper presents a review on the different methods for producing sol-gel micro-capsules and controlled release particles. It also discusses a number of applications of these capsules including advanced sun-screen, antiacne-therapy and self healing cement. It also tries to consider the economic and environmental impact of those sol-gel encapsulation process. Although, the assumption used for the economic and environmental impact remain clearly questionable, the technical review proposed by Pagliaro et al. is a good starting point for anybody wanting to learn about sol-gel encapsulation.
