The invention relates to a method for capsulating microbial, plant and animal cells or biological and chemical substances, using a nozzle to obtain small, especially spherical particles by vibrating an immobilisation mixture. According to said method, the immobilisation mixture, especially a laminar fluid jet taking the form of an immobilisation mixture, is divided into equal parts by superimposition of an external vibration. In a device especially well suited to carry out this method a metallic counter-element (18) which is mounted down-stream from the nozzle (16) at a distance (a) to, and on the outside of, the nozzle axis (A) is connected to a high-voltage source (30). The counter-element is to be embodied by a metal ring (18) through whose through hole (20) the nozzle axis (A) extends. The metal ring (18) is radially connected to an insulated support (22, 24).

1. A method for encapsulating an immobilization mixture comprising the steps of:providing a stream of an immobilization mixture; vibrating the stream wherein the stream is formed into drops by the vibration; subjecting the drops to a magnetic fluid wherein the drops are electrically charged thereby

1. A method for encapsulating an immobilization mixture comprising the steps of:providing a stream of an immobilization mixture; vibrating the stream wherein the stream is formed into drops by the vibration; subjecting the drops to a magnetic fluid wherein the drops are electrically charged thereby resulting in mutual repulsion; and passing the charged drops to a hardening bath for encapsulating.
