摘要：
A biological cell preservation or culturing arrangement (20) comprises a chamber defining a fluid retaining space (30) for retaining in use a body of fluid (34) and a deformable membrane (36) in communication with the fluid retaining space, and being manipulable by an electroactive polymer actuator arrangement (38) to undergo a defined topology change to induce in the fluid a pattern of fluid flow by which fluid is exchanged between a sub-region (46) immediately proximal the deformable membrane and a sub-region (48) removed from the deformable membrane.
