本発明は静電荷パターンを形成した電荷保持媒体上に生

体液等の成分分離方法に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention involves attaching biological tissue to a charge-retaining medium on which an electrostatic charge pattern is formed, and separating components by utilizing the ionic interaction of the tissue. Blood due to electrostatic charge pattern,
This invention relates to a method for separating components of body fluids, etc.
一般に単離した組繊細胞を培養する場合、多くは人工基

はさまざまな環境要因が影響するので、基質との接着は
その一つの要因にしかすぎないが、少なくとも細胞の基
質への粘着、偽足の形成、伸長といった一連の挙動に対
して基質の役割は無視しえないと言われている。Generally, when isolated tissue cells are cultured, most cells cannot proliferate unless they adhere to an artificial substrate. Various environmental factors influence cell proliferation, and adhesion to the substrate is only one factor, but at least it affects a series of behaviors such as cell adhesion to the substrate, formation of pseudopodia, and elongation. On the other hand, it is said that the role of the substrate cannot be ignored.

質を吸着した表面では細胞は単離して増殖することを示
した。By the way, cells are known to have an overall negative charge of -30 to -40 mV in epithelial cell lines based on mucopolysaccharide protein complexes on the cell membrane or sialic acid at the end of sugar chains, and It is said that the charge state influences its adhesion and proliferation. For example, Rembau
showed that the adhesion speed of cells to polyionene, a typical positively charged (quaternary ammonium salt) polymer, was faster than to glass. Furthermore, although the amount of cell adhesion to poly■εMA is small, it has been reported that cell adhesion is improved by copolymerizing 20% diethylaminoethyl methacrylate. Also Macieira-Coe
Lho et al. investigated the proliferation of mouse L or BHK cells on a substrate in which ionic polyamino acids were adsorbed to calf serum albumin fixed with glutaraldehyde. They showed that cells only aggregate and do not proliferate on surfaces that have adsorbed polydine, polyornithine, histones, etc., whereas cells can isolate and proliferate on surfaces that have adsorbed basic polyamino acids or proteins such as polydine, polyornithine, and histones.
このように基材の荷電は、培養細胞の接着、増殖に大き
な影響を持ち、定性的には培地中で正電荷を有するよう
な基材表面上では細胞の吸着速度は増大し、負電荷の基

知られており、全面均一電荷の状態では増殖せず、−船
釣には、アイランド状に電荷を分布させ、かつ電荷の大
きさや間隔を細胞によって異ならせることが増殖の条件
として必要である。In this way, the charge of the substrate has a large effect on the adhesion and proliferation of cultured cells. Qualitatively, the adsorption rate of cells increases on the surface of a substrate that has a positive charge in the medium, and There are many examples of substrates showing the opposite effect. On the other hand, it is also known that if the positive charge is too strong, it causes degeneration of the cells and inhibits their proliferation, and if the charge is uniform throughout the entire surface, they will not proliferate. In addition, it is necessary as a condition for proliferation that the size and interval of charges vary depending on the cell.
ところで、細胞の増殖する最適な電荷パターンはその種
類によって異なっており、これを利用すれば血液中や体

いろな電荷パターンを自由に形成する媒体がないために
、従来実現することかできなかった。By the way, the optimal charge pattern for cell proliferation differs depending on the type of cell, and by using this, it should be possible to separate components in blood and body fluids, but it is possible to freely form various charge patterns. Conventionally, this could not be achieved because there was no medium to do so.

後に適宜の硬化手段で硬化させるものである。If the resin layer is a thermoplastic resin, soften the resin layer by resistance heating the electrode layer, or directly heat the substrate with a heater etc. to soften the resin layer, or if the resin layer is a thermosetting resin or UV rays. For curable resins and electron beam curable resins,
The particle layer forming material is deposited in an uncured state, and after the particle layer is formed, it is cured by an appropriate curing means.

い程度の温度を基板上に加えてもよい。Another means of forming a fine particle layer near the surface of the resin layer is to deposit the particle layer in a single layer or in multiple layers using the same method on a support that has previously been formed and cured on the electrode substrate. let In this case, the particle layer is formed on the surface of the resin layer. After that, the same resin used to form the resin layer or a different insulating resin is laminated to a thickness of 0.1 μm to 30 μm. As a dry method, the resin is deposited by vacuum evaporation, sputtering, etc. The layer may be formed directly, or in a wet method, a solution prepared by dissolving the resin in a solvent may be used to form a film by spinner coating, dipping, blade coating, etc., and then the solvent may be dried. Furthermore, in order to make the particle size uniform when forming the particle layer, a temperature that does not melt the resin layer may be applied to the substrate.

When a thin insulating film of 0OA or less is stacked and a charge is formed on it, a charge with the opposite polarity to this charge is formed on the electrode,
Due to the internal electric field generated between the surface charge and the surface charge, the tunnel effect causes the surface charge to enter the interior through a thin insulating layer, so even in this case, even if a conductive object such as blood is brought into contact with the surface, the internal electric field will leak. You can prevent it from happening.
