Separation of materials is achieved using affinity binding and acoustophoretic techniques. A column provided with a fluid mixture of materials for separation and support structures may be used with acoustic waves to block flow of the support structures. The support structures can have an affinity for one or more materials in the fluid mixture. By blocking flow of the support structures, materials bound or adhered to the support structure are also blocked.

Expanded bed affinity selection

Transducer assemblies that can be used in acoustophoretic systems are disclosed. The acoustophoretic systems including the transducer assemblies and methods of operating the acoustophoretic systems are also disclosed. The transducer assemblies include a housing, a polymeric film attached to the housing, and a piezoelectric material attached to the polymeric film. The piezoelectric material is not attached to, and does not come in direct contact with, the housing. The piezoelectric material is configured to be driven by a drive signal to create a multi-dimensional acoustic standing wave. The piezoelectric material can be attached to the polymer film by an adhesive coating on the polymer film.
