ABSTRACT:
A microfabricated containment capsule has a bulk substrate delimiting a cavity with a boundary, a first portion of which constitutes an inner wall of a solid portion of the bulk substrate. The bulk substrate also provides at a second portion of the boundary a membrane joined to one side of the bulk substrate, the membrane having at least one porous area with controlled pores.
