A method of coating a microneedle array by applying a coating fluid using aflexible film (200) in a brush-like manner. A method of coating a microneedlearray (250) comprising: providing a microneedle array having a substrate and aplurality of microneedles (230)； providing a flexible film； providing acoating solution (210) comprising a carrier fluid and a coating material；applying the coating solution onto a first major surface of the flexible film；performing a transfer step of bringing the first major surface of the flexiblefilm into contact with the microneedles and removing the flexible film fromcontact with the microneedles； and allowing the carrier fluid to evaporate.Also, a method of coating a microneedle array by applying a coating solutiononto a first major surface of a coating substrate to form a layer of appliedcoating solution having a thickness equal to or less than the height of atleast one of the microneedles and performing a transfer step of bringing thefirst major surface of the coating substrate into contact with themicroneedles and removing the coating substrate from contact with themicroneedles, thereby transferring at least a portion of the coating solutionto the microneedle array.
