The disclosure of the present invention is directed to isolated particles having a diameter of ≤ 1,500 nm, obtainable according to the process comprising the steps of (a) forming a highly dispersed colloidal suspension of particles; (b) adding to the suspension an encapsulant material to at least substantially encapsulate individual particles with the encapsulant material; and (c) isolating from said suspension independent and discrete, individually encapsulated or substantially encapsulated particles. |
