Abstract
A microneedle and a chip are disclosed for extraction fluids. The microneedle is provided on a substrate and comprises an elongated body extending from a distal end with a bevel to a proximal end on the substrate along a longitudinal axis. The elongated body comprises a capillary bore extending in a longitudinal direction thereof and defines a fluid path. The proximal end is integrally connected with the substrate and the capillary bore is in fluid communication with a fluid channel of the substrate. The cross-sectional area of the capillary bore in the distal end is larger than the cross-sectional area of the capillary bore in the proximal end.

A microneedle provided on a substrate, comprising:
- an elongated body extending from a distal end thereof with a bevel to a proximal end on the substrate along a longitudinal axis, wherein:
- the elongated body comprises a capillary bore extending in a longitudinal direction thereof and defines a fluid path;
- the proximal end is connected to the substrate and the capillary bore is in fluid communication with a fluid channel of the substrate;
- wherein the cross-sectional area of the capillary bore comprises a triangular cross-section in a perpendicular direction relative the longitudinal direction of the microneedle.
A chip, comprising:
- a plurality of microneedles integrally formed on a substrate, each microneedle comprising:
- an elongated body extending from a distal end thereof with a bevel to a proximal end thereof on the substrate along a longitudinal axis;
- wherein the elongated body comprises a capillary bore extending in a longitudinal direction thereof and defining a fluid path, wherein the cross-sectional area of the capillary bore comprises a triangular cross-section in a perpendicular direction relative the longitudinal direction of the microneedle;
- and
- wherein the proximal end is integrally formed with the substrate and the first fluid path is in fluid communication with a fluid channel of the substrate.
