Abstract

The present invention relates to a high-speed screening and analysis system for reaction optimization. More specifically, the present invention provides a system capable of analyzing samples at low cost through control of fluids using hydrophilic plate-like material (for example, paper), and of analyzing chemical reactions of a sample with a plurality of materials simultaneously, thereby allowing samples to be analyzed rapidly.

First claim

What is claimed is:

1. A high speed screening analysis system for reaction optimization, comprising:
a sample injection part configured to receive a sample;
a plurality of reactant-coated parts, disposed radially around the sample injection part and coated with a substance capable of reacting with the sample;
a plurality of injecting micro channels connecting the sample injection part and the plurality of reactant-coated parts, each of the injecting micro channels being connected with each of the reactant-coated parts;
an absorbing part configured to absorb remaining sample after reaction in the reactant-coated parts;
a plurality of discharging micro channels connecting the plurality of reactant-coated parts and the absorbing part, each of the discharging micro channels being connected with each of the reactant-coated parts; and
a hydrophilic disc-shaped material which is fully coated with a hydrophobic wax except for the sample injection part, the reactant-coated parts, the injecting micro channels, the discharging micro channels, and the absorbing part,
wherein the absorbing part is formed in a continuous ring shape at an edge of the hydrophilic disc-shaped material, and
wherein the reactant of each of the reactant-coated parts consists of a reactant only to detect at least one selected from the group consisting of nickel, copper, iron, zinc, mercury, lead, chromium, cadmium, cobalt, manganese, silver and arsenic,
wherein each of the injecting micro channels and the discharging micro channels has a micropillar structure, and wherein the micropillar structure is comprised of dots patterned with the hydrophobic wax and having a regular arrangement.

2. The high speed screening analysis system for reaction optimization according to claim 1 , wherein:
the high speed screening analysis system is manufactured by patterning of the hydrophobic wax on the hydrophilic disc-shaped material,
the sample injection part is located at a center of the hydrophilic disc-shaped material, each of the injecting micro channel, the reactant-coated part and the discharging micro channel are disposed radially around the sample injection part, and
the edge of the hydrophilic disc-shaped material forms the absorbing part.

3. The high speed screening analysis system for reaction optimization according to claim 2 , wherein:
the hydrophilic disc-shaped material is paper.

4. The high speed screening analysis system for reaction optimization according to claim 1 , wherein:
the sample injection part comprises a sample injection pad configured to absorb the sample,
the sample injection pad is coupled to protrude from a surface of the hydrophilic disc-shaped material, and
the sample injection pad is made of the same material as the hydrophilic disc-shaped material.

5. The high speed screening analysis system for reaction optimization according to claim 1 , wherein:
the absorbing part comprises a sample absorbing pad in which the sample is absorbed,
the sample absorbing pad is coupled to protrude from a surface of the hydrophilic disc-shaped material, and
the sample absorbing pad is made of the same material as the hydrophilic disc-shaped material.
