Bent microstructures for sampling, transporting or dispensing a fluid media
View Patent ↗A device for sampling, transporting and/or disposal of fluid media in the nl and μl-range comprises a substrate with an open or closed capillary-like groove or channel respectively, the substrate with the open or closed groove or capillary respectively is bent or arcuated at least at one location. The substrate comprises at least one end into which the open or closed capillary-like groove or channel respectively is extended, which end is shaped according to its application or use as e.g. needle-like, straight-lined cut, tip-like, at least most half circle-shape, rounded, etc.
1. A device for sampling, transporting and/or disposal of fluid media via capillarity in the nanoliter (nl) to microliter (μl) range comprising a substrate defining a substrate plane and having at least one etched channel disposed within the substrate and at least one longitudinal extending strip like portion disposed within the at least one etched channel and bent at least at one location out of the substrate plane, the strip like portion is provided with a fluid channel which provides a capillary force to the fluid media when contacted therewith wherein the fluid channel is disposed at least at the bend of the strip like portion.
2. The device according to claim 1 wherein the fluid channel is open and arranged along the side of the strip like portion defining the inside surface of the bend of the strip like portion.
3. The device according to claim 1 wherein the fluid channel is open and is arranged along the side of the strip like portion defining the outside surface of the bend of the strip like portion.
4. The device according to claim 1 wherein the fluid channel is open and is arranged along the sides of the strip like portion defining the inside and outside surfaces of the bend of the strip like portion.
5. The device according to claim 1 wherein the strip like portion comprises at least one end to which the fluid channel is extended, said end is provided with a shape selected from the group comprising needle-like, straight-lined cut, and rounded.
6. The device according to claim 1 wherein at least the strip like portion is a deformable material comprising a metal, a polymer, and combination thereof.
7. The device according to claim 1 wherein the bent location has a bend-angle that is in the range between 60 and 120°.
8. The device according to claim 1 wherein positioning elements are provided to enable relative adjustment of the strip like portion to the substrate plane.
9. The device according to claim 1 wherein the strip like portion is a plurality of the strip like portions provided on the substrate.
10. The device according to claim 1 wherein the fluid channel is closed and arranged along the side of the strip like portion defining the inside surface of the bend of the strip like portion.
11. The device according to claim 1 wherein the fluid channel is closed and is arranged along the side of the strip like portion defining the outside surface of the bend of the strip like portion.
12. The device according to claim 1 wherein the substrate has a shape selected from the group comprising circular, rectangular, square, hexagonal, and disk-like.
13. The device according to claim 1 wherein the strip like portion comprises at least one end to which the fluid channel is extended, and wherein said end is resilient.
14. A structure containing the device according to claim 1 .
15. The structure according to claim 14 wherein said strip like portion is a plurality of strip like portions and said structure comprises a plate having two or more individual grooves, said plate being provided adjacent said substrate such that said grooves is configured to be source of the fluid media for a respective fluid channel of said strip like portions.
