LATERAL FLOW DEVICE FOR SIMULTANEOUS QUANTITATIVE ANALYSIS OF MULTI-COMPONENT

摘要

The present invention provides a lateral flow device comprising the following: a sample pad for accommodating a fluid sample to be analyzed; a conjugate pad arranged in contact with the sample pad and including nanospheres coated with a first binder that is combined with different target analytes included in the fluid sample; and a patterned sheet arranged in contact with the conjugate pad and having a branched channel pattern formed to make the fluid sample flow, wherein the channel pattern is formed by spraying a pattern material on a base material composed of paper using an ink-jet printing method. The lateral flow device for simultaneous quantitative multi-component analysis according to the present invention does not need a clean room or a high-priced complex facility and can be mass-produced as the channel pattern is formed on a base composed of paper using the ink-jet printing method. In addition, the present invention can contribute to the growth of environment and energy industries and bio-industry via biotechnology and chemical applications as the simultaneous quantitative multi-component analysis can be conducted to explain the physicochemical phenomena of various particles via the design and manufacture of a high-throughput diagnostic device and ultra-high-precision imaging process technology or to provide basic materials to various biochemical substance diagnoses or the application or development of in-vitro experimentation.
