The present disclosure relates to a method for manufacturing a body comprising a particle structure fixated in a matrix material, said method comprising the steps of: providing a mixture of a viscous matrix material and particles, subjecting said particles to an acoustic standing wave, so as to arrange at least portion of said particles in a pressure node and/or a pressure antinode of the acoustic standing wave thereby creating a particle structure In said viscous matrix material and fixating said viscous matrix material so as to fixate said particle structure In said matrix material. The disclosure also relates to a body obtained by said method, and to the use of said method in various applications.
