Abstract:
본 발명의 세포배양 기판은, 3차원적 세포 배양 환경을 효과적으로 제공하기 위해 중요하게 고려되어야 할 몇 가지 관점을 만족시키는 미세구조를 갖는다. 이러한 미세구조는 꽃 유사 형상의 3차원 미소 펠렛 형태로 세포 배양 및 응집이 일어나며, 세포 배양시 탈분화를 억제하고 재분화를 촉진하고, 세포 골격 구조의 발달을 억제하며, 세포의 유동성 및 이동성을 증가시킨다.
Abstract:
PURPOSE: A cell culture substrate is provided to suppress development of a cytoskeleton structure and dedifferentiation during cell culture and to promote redifferentiation. CONSTITUTION: A cell culture substrate has a thin film on which microparticles are arranged. A three-dimensional micropellet is formed while cells are cultured. The three-dimensional micropellet has a flower shape with a core and petal patterns around the core. The core is formed by aggregation of cells in a three-dimensional form. The cell culture substrate has low cell culture rate and high redifferentiation rate.
Abstract:
PURPOSE: A surface modification method of lithium niobate substrate is provided to increase bonding strength of an organic thin film with lithium niobate substrate through a mixed process of drying and wet surface process. CONSTITUTION: A surface modification method of lithium niobate substrate comprises the following step: activating lithium niobate substrate surface by mix processing dry surface process and wet surface process. The dry surface processing irradiates one of the following: ultraviolet ray (UV), ozone (O3), ultraviolet ray/ozone (UV/O3) and plasma. The wet surface processing dips the lithium niobate substrate which has activated crystal surface into a surface modifying solution which can form a self assembled monolayer(SAM). The surface modifying solution includes a compound which introduces functional group through fixation on the lithium niobate substrate.
Abstract:
PURPOSE: A support for culturing stem cells is provided to control stem cell growth form and speed and to differentiate special cells. CONSTITUTION: A method for controlling proliferation and differentiation of stem cell comprises a step of controlling network structure CNT membrane thickness and surface roughness of CNT membrane using more than 0.5 ml of carbon nanotube solution dispersed in an organic solvent. The stem cell is mesenchymal stem cells(3).
