An integrated device for a sample collection and transfer is provided. The integrated device comprises a capillary channel disposed between a first layer and a second layer, wherein the first layer comprises a hydrophilic layer comprising a fluid inlet for receiving a sample fluid to the capillary channel, wherein the capillary channel comprises an inner surface and an outer surface; and an outlet for driving out the sample fluid. The device further comprises a third layer comprising an adhesive material such as a patterned adhesive material, and a flow path, wherein the third layer is disposed on the outer surface of the capillary, at a determining position relative to the outlet, such that the capillary is in contact with the third layer and the outlet is in contact with the flow path of the third layer for allowing the sample fluid out from the integrated device.
