DETERMINATION OF MECHANISM FOR MOLECULAR ADHESION TO SOFT TISSUES AND MATERALS PREPARATION

在这项研究中，确定了聚合物结构，以使聚合物粘附在组织上。聚合物的分子设计注重从物理化学和生物两个方面对细胞/材料相互作用的调节。在常温下，聚合物的相变和自发组织使其易于固化，并实现规定的粘附。严密地规定了该聚合物的分子结构并组成了它，并对创面制作的软组织黏附材料的原型进行了黏附性能和安全性的检验。一个想法是制备纳米粒子作为探针来识别我迄今为止发现的特定反应分析技术；并规定官能团，它可以附着在细胞中，配体分子的结构。首先将各种官能团与疏水性、电荷、氢键连接起来，利用物理化学相互作用。将具有特定官能团固定作用的水溶性磷脂聚合物作为表面处理材料，将聚合物溶液制成O/W乳液并制备纳米颗粒。高密度引入官能团，与细胞相互作用。可以实现细胞和组织的粘附。为了确定这种聚合物与细胞结合的结构和组成，它变成了单层，并检查了细胞的回复以及一种形式，增加的数量，测量了细胞内酶活性，以考虑特定的细胞活性，它规定了聚合物组成，化学结构不影响细胞比这些。另一方面，对聚合物进行了降低粘接性能的分子设计，并从防止组织粘接的角度进行了考察。

In this study the polymer structures were determined to adhere the polymer to tissues. The molecular design of the polymers were carried out with attention to the regulation of cell/materials interactions from of the physical chemistry and the biological both sides. The polymers could easily solidify themselves by the phase transition of the polymers and voluntary organization as far the normal temperature and to realize the adhesion prescribed it. It prescribed the molecular structure of this polymers closely and composed it, and the wound produced the soft tissue adhesion materials of the prototype than adhesion performance and examination of the safety.A thought prepared nanoparticles as a probe for recognizing the specific reaction analytical technique that I found so far; and to prescribe the functional group, which could adhere for a cell, the structure of the ligand molecule. At first the functional groups with various hydrophobicity, electric charge, hydrogen bonding connected to use physicochemical interaction. The water-soluble phospholipid polymers, which did immobilization of the specific functional group was used for surface treatment materials and the polymer solution for making an O/W emulsion and manufactured nanoparticles.The functional groups cold introduce with high-density for suitable interaction with cells. The adhesion of cells and tissues could be achieved. To determine the structure and composition bonded this polymer to the cells, which became single-layered and examined the reply of the cell As well as a form, the number of the increases, the intracellular enzyme activity was measured to consider in particular cell activity It prescribed polymer composition, the chemical structure that did not affect a cell than these. On the other hand, a molecule design about the polymers was carries out to reduce adhesive property and performed examination form the viewpoint of prevention of organization adhesion.
