It is known to use capillary transport zones to convey drops of patient sample to a test area along a given path. Such a path is defined by a pair of opposing surfaces which are spaced apart by a capillary distance and are held together by means of an adhesive. Plastics materials which are preferred for the construction of such transport zones tend not to be readily wettable and high equilibrium contact angles result. Described herein is a device (110) for providing liquid transport, and a method of making such a device. The device (110) features a capillary transport zone (140) comprising opposing surfaces (134, 136, 170) which are formed from supporting material (130, 132) having unsatisfactory wettability. The wettability is improved by applying a coating (20) of an adhesive to at least one of the opposing surfaces (134, 136, 170). |
