Synthesis procedure starting with (a) mixing of equal volumes of buffered CaCl2 and Na2CO3 for 10 s with a magnetic stir bar, followed by a two-step coating procedure starting with APTMS. b The CaCl2-APTMS solution was placed in a shaker for ~2.5 h. Particles were then coated with (c) TEOS and placed in a shaker for 5.5 hours. The two-step coating procedure was then repeated.
