Abstract: A method of coating a microneedle array by applying a coating fluid using a flexible film in a brush-like manner. A method of coating a microneedle array comprising: providing a microneedle array having a substrate and a plurality of microneedles; providing a flexible film; providing a coating solution 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 flexible film into contact with the microneedles and removing the flexible film from contact with the microneedles; and allowing the carrier fluid to evaporate.
