Abstract: In accordance with an embodiment, a microfluidic chip including a first cells enrichment system and a second cells enrichment system is provided. Channel layouts of the first and the second cells enrichment systems are symmetric with respect to a reflection plane vertical to the microfluidic chip. Each of the first the second cells enrichment systems includes a first fluid channel, a second fluid channel, a sample channel, an inlet channel, and a filtration chamber. The sample channel of the first cells enrichment system has a first inner wall and a first outer wall. The sample channel of the second cells enrichment system has a second inner wall and a second outer wall. The first outer wall and the second outer wall are both far from the reflection plane. A distance between the first outer wall and the second outer wall is in the range from about 10 ?m to about 1 cm.

Abstract: In a biosensor measuring system, a biosensor includes a bio-sensing unit embedded in a main body formed with a visually identifiable character pattern that corresponds to identification information associated with the biosensor. A biosensor measuring device includes an image capturing unit for capturing an image of the character pattern. An image processing unit identifies the captured image to obtain identification data, which is displayed on a display unit. A signal processing unit analyzes a reactive signal generated by the bio-sensing unit and associated with a specific component in a test sample based on an input signal, which is generated by an input unit when the displayed identification data matches the character pattern, to obtain a measurement result.
