聚乙二醇(PEG)是一种人工合成的亲水性生物相容聚合物,在PEG化、表面共轭、纳米颗粒涂层和水凝胶交联等方面具有广泛应用。
应用
聚乙二醇6000是一种非离子表面活性剂,可用作结构导向剂以制备介孔γ-Al2O3。PEG 6000可诱导薄水铝石纳米颗粒形成片状结构形态,具有更高的比表面积、更大的孔体积和孔径等纹理性能。它也用于药物制剂中,以提高水溶性差的药物分子的溶解速度。PEG-6000也可用于选择性沉淀法纯化核酸。该方法比常用的色谱纯化方法更经济高效,且速度快。
Polyethylene glycol (PEG) is a synthetic, hydrophilic, biocompatible polymer that has a wide range of uses in PEGylation, surface conjugation, nanoparticle coating, and crosslinking for hydrogels, etc. PEGs are made by polymerizing ethylene oxide via a ring-opening reaction to produce a wide range of molecular weights and molecular weight distributions (polydispersity).
Application
Polyethylene glycol 6000 is a non-ionic surfactant that can be used as a structure-directing agent to prepare mesoporous γ-Al2O3. PEG 6000 induced the formation of the lamellate structure morphology of boehmite nanoparticles with improved textural properties such as high surface area, larger pore volume, and pore size.It is also used in drug formulations to enhance the dissolution rate of the poorly water-soluble drug molecule.PEG-6000 can also be used in the purification of nucleic acids via the selective precipitation method. This approach is economically cost-effective and faster than the commonly employed chromatographic purification method.
