Biodegradable Microneedles for Transdermal Drug Delivery

n the final section of this thesis it is described an additional application regarding the manipulation of biomaterials by the pyro-EHD effect. In particular, the pyro-electric field is applied for the deformation of biomaterials into a conical tip that could be assimilated to the shape of a needle. The fabrication process is studied and characterized for different kind of polymers and the final 3D microstructures produced are tested for biomedical application.
