Method and device for producing a printed microarray and verifying the same

A device for manufacturing a microarray and verifying said microarray, the device comprising:

• a print head adapted to load at least one reagent, the print head being adapted to move at a determined speed with respect to a substrate and to dispense said at least one reagent on the substrate, during a print pass, to obtain a microarray,
• illumination device for illuminating the substrate,
• a camera for obtaining an image of the printed microarray on the substrate,
• processing device connected to said camera for processing the obtained image to verify the microarray,
• wherein the illumination device and the camera are connected to the print head and are adapted to move with respect to the substrate together with the print head, the illumination device and the camera being positioned to move behind the print head, the camera being located at a determined distance from the print head, wherein the device further comprises:
• control device adapted to control the movement of the assembly of the print head, illumination device and the camera with respect to the substrate, the control device being adapted to receive information related to an optimal time interval between the steps of printing the microarray, illuminating the substrate, and obtaining an image, said optimal time interval being based on the substrate and the reagent, the control device being adapted to modify the determined speed to move the assembly of the print head, illumination device and the camera with respect to the substrate at the modified determined speed to allow obtaining the image of the microarray after said optimal time interval.
