Abstract
A structure is provided comprising a number of surfaces 10, 20 joined together with an adhesive 30, said structure being configured to reshape upon at least partial degradation of the adhesive 30. Related method and uses are further provided.
Claims16
A structure, comprising:
- a plurality of surfaces;
- and
- an adhesive layer, as an Atomic Layer Deposition (ALD) coating layer of thickness 0.1-100 nm on all surfaces of the structure,
- wherein the plurality of surfaces are joined together by the adhesive layer in a first configuration having a collapsed shape,
- wherein the structure in the first configuration bears a mechanical load resulting from the adhesive layer joining said plurality of surfaces together and forming the collapsed shape, and
- wherein the adhesive layer is configured to at least partially degrade and thereby permit the plurality of surfaces to detach from one another and release the mechanical load, the structure configured so that when the mechanical load is released the structure reshapes itself from the collapsed shape into a second configuration having an original shape corresponding to a shape the structure had prior to the surfaces being joined together by the adhesive layer.
3 more elements
A method for manufacturing a structure, comprising:
- obtaining a structure having a plurality of surfaces, said structure configured to have an original shape;
- applying an adhesive to all surfaces of the structure by Atomic Layer Deposition (ALD);
- and
- joining said surfaces together with the adhesive so that said structure assumes a collapsed shape different from said original shape,
- wherein the structure is configured to bear a mechanical load when in the collapsed shape and held by the adhesive, and
- wherein the adhesive is configured to at least partially degrade in order to permit release of the mechanical load and thereby cause the collapsed structure to reshape and acquire the original shape that the structure had prior to the surfaces being joined together.
3 more elements
A method for delivering at least one pharmaceutically active agent into the body, wherein said at least one pharmaceutically active agent is provided in a structure comprising a plurality of surfaces joined together with an adhesive provided in the form of a coating layer applied by Atomic Layer Deposition (ALD),
- wherein said structure is configured to release said pharmaceutically active agent upon at least partial degradation of the adhesive in the body.
