Abstract
A biomedical testing sheet comprises: a substrate with calligraphy paper material, wherein the substrate comprises a wax pattern layer, which is a part of a surface of the substrate coated by a waxy material, and penetrated and diffused by the waxy material, and the wax pattern layer comprises one or more carrying units for carrying one or more droplets of liquids to be measured. The lotus effect substantially prevents diffusion of the liquids and reagents on the carrying units, and reduces the required amount of liquids to be measured and the amount of agent.
Claims14
A biomedical testing sheet, including:
- a substrate with calligraphy paper material,
- wherein the substrate comprises a wax pattern layer, which is a part of a surface of the substrate that is coated with a waxy material, and penetrated and diffused by the waxy material, and
- the wax pattern layer comprises plural carrying units that are completely diffused with the waxy material and laterally surrounded by the calligraphy paper material with no waxy material diffused thereinto and protrude from the substrate for carrying one or more droplets of liquids to be measured, and
- the calligraphy paper material with no waxy material diffused thereinto separates the carrying units from one another.
A method for manufacturing a biomedical testing sheet, comprising steps of:
- coating a waxy material on a surface of a substrate, wherein the substrate is calligraphy paper material;
- heat treating the waxy material to make the waxy material penetrate the substrate to form a wax pattern layer, the wax pattern layer formed into plural carrying units that are completely diffused with the waxy material and laterally surrounded by the calligraphy paper material with no waxy material diffused thereinto and protrude from the substrate for carrying one or more droplets of liquids to be measured, wherein the calligraphy paper material with no waxy material diffused thereinto separates the carrying units from one another.
