Abstract
A microneedle array has a plurality of microneedles, said microneedles being supported by a substrate. In order to improve the properties of the microneedle array, the substrate is in the form of a grid structure or comprises a grid structure.
Claims17
A microneedle array comprising:
- a plurality of microneedles;
- and
- a support layer supporting the plurality of microneedles,
- wherein the support layer is formed as a grid structure or comprises a grid structure,
- wherein the grid structure has a plurality of crossing points, the crossing points being at least partially connected with the plurality of microneedles, and
- wherein a material forming the plurality of microneedles surrounds at least one crossing point of the grid structure.
3 more elements
A molding for manufacturing a microneedle array comprising:
- a base body having a plurality of depressions,
- wherein a plurality of channels are provided for forming a grid structure on an upper side of the base body, such that the molding yields a microneedle array comprising:
- a plurality of microneedles;
- and
- a support layer supporting the plurality of microneedles,
- wherein the support layer is formed as a grid structure or comprises a grid structure,
- wherein the grid structure has a plurality of crossing points, the crossing points being at least partially connected with the plurality of microneedles, and
- wherein a material forming the plurality of microneedles surrounds at least one crossing point of the grid structure.
5 more elements
A method for manufacturing a microneedle array, the method comprising the steps of:
- metering one or several materials into depressions extending from an upper side of a molding;
- and
- linearly applying a material to the upper side of the molding in order to form a grid structure, such that the method for manufacturing a microneedle array yields a microneedle array comprising:
- a plurality of microneedles;
- and
- a support layer supporting the plurality of microneedles,
- wherein the support layer is formed as a grid structure or comprises a grid structure,
- wherein the grid structure has a plurality of crossing points, the crossing points being at least partially connected with the plurality of microneedles, and
- wherein a material forming the plurality of microneedles surrounds at least one crossing point of the grid structure.
