Disclosed are a method and a device for transferring a nanoparticle monolayer by using a capillary tube, wherein a nanoparticle monolayer present in a liquid-gas interface is locally and selectively separated and then transferred to a substrate by using a capillary tube. Accordingly, nondestructive and reproducible transfer can be made regardless of the surficial properties and structures of the substrate to which the monolayer is to be transferred. Therefore, the method and the device enable an in-situ high-speed inspection of harmful materials, such as an illegal drug and a residual pesticide, on surfaces of various solids such as fiber clothes, food and banknotes, and can be easily coupled to a microfluid channel having a small size and a complicated structure. Further, the method and the device can transfer a nanoparticle monolayer in a simple and inexpensive process without using special and expensive equipment.
