Zusammenfassung:	A microneedle and a chip are disclosed for extraction of fluids. The microneedle (101) provided on a substrate (102), comprises an elongated body (503) extending from a distal end (504) with a bevel (505) to a proximal end (506) on the substrate along a longitudinal axis; the elongated body comprises a capillary bore (507) extending in a longitudinal direction thereof and defines a fluid path (508); the proximal end is integrally connected with the substrate and the capillary bore is in fluid communication with a fluid channel (309) 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.
