Abstract: This invention relates to a polymer membrane comprising a hydrogen bond donor polymer and a hydrogen bond acceptor polymer and to the use of such membrane as the shell of a capsule. The invention also relates to a method of manufacturing a polymer membrane comprising a step of contacting an aqueous phase comprising a first polymer, and an oil phase comprising a second different polymer; wherein one polymer is a hydrogen bond donor polymer and the other polymer is a hydrogen bond acceptor polymer. The invention also relates to a method of encapsulation comprising a step of manufacturing a polymer membrane.

Abstract: The invention relates to a fluidic device for producing platelets from a suspension of megakaryocytes or their fragments, comprising a production chamber comprising at least one channel in which a suspension of megakaryocytes is introduced to flow from its inlet to its outlet wherein said channel is textured with a plurality of obstacles on at least one portion of its inner surface. The invention is further directed to an ex vivo method for producing platelets from megakaryocytes using a fluidic device as defined above.
