Claim 12:
13. A bi-phase layer-by layer process for forming the plurality of superficially porous particles of claim 1, comprising:
(a) mixing an aqueous bottom phase and an organic top phase for a mixing duration to form a bi-phase mixture, wherein:
the aqueous bottom phase includes a plurality of core particles (or modified core particles in (e)), a template, and a catalyst; and
the organic top phase includes an organic solvent and a silane precursor;

(b) heating the bi-phase mixture under reflux conditions for a refluxing duration to form modified core particles;
(c) cooling the bi-phase mixture to room temperature;
(d) separating the plurality of modified core particles from the bi-phase mixture; and
(e) repeating (a)-(d).
