Disclosed herein are a transparent immunoassay apparatus and method. The transparent immunoassay apparatus includes a sample pad configured to allow a liquid specimen to be dropped thereonto, a first porous pipe configured to move the dropped specimen in a lateral flow manner, an immunobinding reaction unit configured to generate a detectable signal from binding of a previously applied reactant and the specimen between transparent upper and lower plates of the immunobinding reaction unit, a second porous pipe configured to move the specimen, having passed through the immunobinding reaction unit, in a lateral flow manner, and an absorption pad configured to absorb the specimen transferred from the second porous pipe.

Transparent immunoassay apparatus and method

A method for diagnosing Alzheimer's disease by detecting the presence of beta-amyloid in cells using a phototransistor device. Cells that potentially contain beta-amyloid are provided and labeled with a multi-protein that selectively binds to beta-amyloid if present and that includes streptavidin, biotin and polyethylene glycol connected in sequence with the streptavidin being bound to a magnetic bead and the polyethylene glycol being bound to the beta-amyloid, to provide labeled cells. A phototransistor device including a channel layer is provided and a difference in photocurrent determined corresponding to incident light measured before and after selectively fixing the labeled cells on a surface of the channel layer by applying an external magnetic field effective to attract the magnetic bead to the phototransistor device through a permanent magnet positioned below the channel. Any difference between the first and second photocurrents indicates the presence of, and optionally amount of, labeled beta-amyloid in the cells.

Disclosed herein is a method of fabricating a CIS or CIGS thin film, comprising:

Method of fabricating CIS or CIGS thin film

Disclosed are a high density CIS thin film and a method of manufacturing the same, which includes coating CIS nanopowders, CIGS nanopowders or CZTS nanopowders on a substrate by non-vacuum coating, followed by heat treatment with cavities between the nanopowders filled with filling elements such as copper, indium, gallium, zinc, tin, and the like. The high density CIS thin film is applied to a photo-absorption layer of a thin film solar cell, thereby providing a highly efficient thin film solar cell.

Method of manufacturing high density CIS thin film for solar cell and method of manufacturing thin film solar cell using the same

Disclosed is a method of manufacturing a thin-film light-absorbing layer using spraying, including mixing precursor solutions comprising CuCl, InCland SeC(NH)under a nitrogen atmosphere at room temperature thus preparing a mixture solution; spraying the mixture solution on a substrate and drying it, thus forming a thin film; and selenizing the thin film under a selenium atmosphere. A method of manufacturing a thin-film solar cell is also provided, which includes forming a back contact layer on a glass substrate using sputtering; forming a light-absorbing layer on the back contact layer using spraying; forming a buffer layer on the light-absorbing layer using chemical vapor deposition; forming a window layer on the buffer layer using sputtering; and forming an upper electrode layer on the window layer.
