Abstract
A functional material for testing a liquid sample includes a based material in a sheet shape and a channel part provided on a mounting surface of the base material wherein the channel part is composed with water-permeable fibers having permeability, and water-impermeable fibers having impermeability. The water-permeable fibers and the water-impermeable fibers are arranged along the longitudinal direction of the channel part, forming voids wherein the voids are in a mesh structure in which one of the voids connects to another of the voids such that the empty spaces are linked from a base end to a tip end of the channel part. A thickness of the channel part is ranged from 20 μm mm to 5 mm, and a width of the voids is ranged from 10 μm to 200 μm, allowing the liquid sample to move from the base end to the tip end due to capillarity.
