Ultrasonic standing waves fields can act on particles in suspension and can concentrate them in
nodal (or antinodal) planes of acoustic pressure. This principle of ultrasonic cell trapping is
applied in numerous biotechnological applications, such as mammalian cell filtering and red
blood cells sedimentation. We developed a new ultrasound-based cell immobilisation technique,
which allows the manipulation of cells/particles in different gel matrices. This creates a defined
distribution of particles entrapped within the gel. The challenge now is to develop novel
biotechnological applications of this new technique. The paper discusses the potentials of
ultrasonic cell manipulation as a new cell-immobilisation/encapsulation technology.
