Imparting inorganic compositions into patchy particles will allow functional materials to be coupled in complex architectures that have potentially new emergent properties. Here we demonstrate a kinetically-controlled approach which can encapsulate inorganic clusters into patchy particles. This method avoids the swelling process and is only relevant to the cluster's surface property. Silicon dioxide and titanium dioxide patchy particles are obtained with various numbers of patches that adopt highly symmetrical geometries . The patchy size can be varied systematically via the modification of three parameters: amount of matrix material, surfactant concentration and reaction time.
