Abstract:
1. A process for making particles comprising a hydrophobic dopant therein said dopant being releasable from the particles, the process comprising: forming an emulsion comprising a hydrophilic phase and a hydrophobic phase dispersed in the hydrophilic phase, said hydrophobic phase comprising a precursor material and the dopant; adding an aminofunctional silane catalyst to the emulsion, whereby the catalyst penetrates into the hydrophobic phase; and reacting the precursor material in the presence of the catalyst to form the particles comprising the dopant therein, wherein (i) each of the particles is a porous solid particle and (ii) the dopant is distributed substantially homogeneously within and is releasable by diffusion from each particle.
