Abstract
Provided is a biosensor including a capillary unit having a capillary channel therein and a reagent disposed in the capillary channel, the reagent being configured to develop colors in a sample, and a measuring unit configured to measure a degree of color development of the sample in the capillary channel.
Claims10
A biosensor comprising:
- a capillary channel and a reagent disposed in the capillary channel, the reagent being configured to develop colors in a sample;
- a first pin hole disposed on one side of the capillary channel;
- a light source configured to emit light through the first pin hole;
- a second pin hole disposed on an opposite side of the capillary channel from the first pin hole, the first and second pin holes penetrating sidewalls of the capillary channel;
- and
- a light detector disposed behind the second pin hole and configured to receive light emitted from the light source after it has passed through the first pin hole and the capillary channel and to generate color data from the light;
- wherein the first pin hole, the second pin hole, the light source and the light detector are all disposed along a linear axis, and
- wherein the light detector transmits the color data to a controller that is configured to use the color data to calculate a concentration of biomaterial in the sample, and
- wherein the first and second pin holes are in fluid communication with the capillary channel.
