  • Patent number: 12268833
    Abstract: A microarray receptacle which has a first side and a second side. Furthermore, the microarray receptacle includes a carrier structure for connecting the microarray receptacle to an application point. To the carrier structure there is connected a carrier surface which in turn is connected to a microarray. An articulation device is arranged between the carrier surface and the carrier structure, the articulation device making possible movement of the microarray connected to the carrier surface relative to the carrier structure along the extent of the microarray. Further, a microarray receptacle cluster with a plurality of such microarray receptacles.

  • Publication number: 20230347550
    Abstract: A mold element, in particular a casting mold for manufacturing microstructures, in particular microneedle arrays, includes a base body. On an upper side of the base body, several depressions for receiving material for manufacturing the microstructure are provided. In order to improve the quality of the microstructure to be manufactured, in particular during a drying process, channels are provided on the upper side of the base body, each of which is connected to at least one of the depressions.

  • Publication number: 20220072290
    Abstract: The disclosure relates to an applicator the application of a microarray. The applicator includes a housing and a plunger that can move within said housing to accelerate the microarray. The applicator additionally includes a target force trigger, and said target force trigger secures the plunger in relation to the housing and releases the movement thereof when the target force is applied. The disclosure also relates to an application system for application of a microarray, including such an applicator and a microarray or a microarray receiving portion, preferably connected to a microarray receiving portion cluster, having a microarray. The microarray or the microarray receiving portion are arranged relative to the applicator and/or connected to the applicator such that the plunger is able to apply the microarray.

  • Publication number: 20220062605
    Abstract: The invention relates to an applicator for application of a microarray, comprising a housing (10) in which a plunger (20) is arranged such that it can move linearly. A retainer element (38) is also provided for receiving a microarray (28). A pressure element (34) makes it possible for the plunger (20) to be displaced in order for it to act upon a microarray (28) receive by the retainer element (38). An actuation element (44) allows the plunger (20) to be held in an internal position, and this can be released by actuating said actuation element (44).
