The present invention relate to a method and corresponding apparatus for just in time mixing of a solid or powdered formulation and its subsequent delivery to a biological body. In some embodiments, a powdered formulation is maintained in a first chamber. A bi-directional electromagnetic actuator is in communication with the chamber. The actuator, when activated, generates a pressure within the first chamber. The pressure results in mixing of the powdered formulation and a diluent in time for delivering into the biological body.
