Microparticles/microcrown

A device for producing a microparticle, the device comprising:

• a first mould;
• and
• a second mould,
• wherein
• the first mould and the second mould are adapted such that,
• in a closed position, the first mould and the second mould define a micro-cavity and are pressed against each other to compress a pliable moulding material within the micro-cavity, wherein a shape of the micro-cavity corresponds to a shape of the microparticle, and
• in an open position, one of the first mould and the second mould adheres to the microparticle while the other separates from the microparticle,
• wherein one of the first and second moulds is dimensioned such that it sticks to the moulded microparticle and wherein the other of the first and second moulds is dimensioned such that it does not hold or stick to the moulded microparticle.

A method of producing a microparticle, the method comprising:

• providing a mould assembly, which comprises two moulds that comprise a stationary mould and a moveable mould, wherein one or both of the stationary and moveable moulds comprises an inner surface including a mould-body surface and several mould-spike surfaces with several partial mould-spike surfaces,
• positioning the mould assembly in an open position, wherein the stationary and moveable moulds are separated from each other,
• providing a polymeric material to the mould assembly in the open position, wherein the polymeric material is more pliable than the mould assembly,
• positioning the mould assembly in a closed position to define a micro-cavity,
• pressing the moveable moulds against the stationary mould to cause the stationary and moveable moulds to compress the polymeric material within the micro-cavity to take up the shape of the micro-cavity to form the polymeric material into a microparticle, and
• positioning the mould assembly in the open position after the microparticle is moulded, wherein the microparticle adheres to one of the two moulds of the mould assembly,
• wherein one of the stationary and moveable moulds is dimensioned such that it sticks to the moulded microparticle and wherein the other of the stationary and moveable moulds is dimensioned such that it does not hold or stick to the moulded microparticle.
