Abstract
A measuring apparatus for a biochemical compound has a channel structure having an inlet port and an outlet port. A passageway extends between the inlet and outlet ports for passing a liquid sample therethrough. The passageway has its inside walls lined with a layer of hydrophilic material. A biosensor is provided in the passageway to detect a biochemical compound contained in the liquid sample. Preferably, the hydrophilic material comprises a metal oxide having a photocatalytic characteristic, which is illuminated with ultraviolet rays.
