본 발명은 3차원 세포 배양 용구 및 이를 이용한 세포의 3차원 배양 방법 에 관한 것이다. 본 발명의 3차원 세포 배양 장치 및 이를 이용한 3차원 세포 배양 방법은 나노 입자가 포함된 배양액에서 세포를 기초 배양하여, 자성 나노 입자를 세포 내 또는 세포막에 도입시키고, 상기 자성 나노 입자가 도입된 세포에 자성을 인가하여 별도의 표면 처리 없이, 배양액 내의 부유 상태에서 스페로이드를 형성할 수 있는 효과를 나타낸다.
Abstract:
The present invention relates to a 3-dimensional cell culture instrument using a hollow tube and a 3-dimensional cell culture method using the same, and more particularly, to a 3-dimensional cell culture instrument including a plurality of cell receiving portions each having a hollow tube therein, and a 3-dimensional cell culture method using the same. As for the 3-dimensional cell culture instrument, the hollow tube is formed in the cell receiving portion. Therefore, even when the 3-dimensional cell culture instrument is simply immersed in a culture liquid inside a culture plate, in which cells are cultured, the cell culture liquid is absorbed into the hollow tube due to a capillary phenomenon and a surface tension of the hollow tube. The absorbed cell culture liquid forms a liquid droplet on the end in the hollow tube, and cells in the liquid droplet cohere together due to the gravity to form a spheroid. Thus, the present invention can perform a 3-dimentional culture of cells more easily and conveniently as compared with the conventional art.
Abstract:
PURPOSE: A method for manufacturing a hormone sensor and the hormone sensor manufactured by the same are provided to obtain a human hormone sensing system by using a human hormone receptor protein as a primary signal converter and be utilized as a tool for a diseases-diagnosis and a physical examination. CONSTITUTION: A method for manufacturing a hormone sensor is as follows. An amine group is introduced on a surface of a substrate. A conductive polymer nano structure is fixed to the surface of the substrate. A hormone receptor is attached to the conductive polymer nano structure.
