Abstract: A process for the production of a three-dimensional particulate structure embedded in a body formed of a hydrogel matrix, comprising the steps of forming a layer of a hydrogel matrix having a particulate substructure embedded therein by subjecting a suspension of particulates in a layer of a hydrogel matrix precursor to standing acoustic waves (SAWs) to spatially partition the particulates within the layer of hydrogel precursor into a particulate substructure and allowing the hydrogel precursor to solidify such as to form the layer of a hydrogel matrix having a particulate substructure embedded therein, and repeating the process until the three-dimensional particulate structure embedded in a body formed of a hydrogel matrix is formed.
