Abstract

In this study, the interaction of \(\beta\)-carboxymethyl cyclodextrins (CMCD) with monomolecular layers composed of a mixture of electroneutral and cationic lipids on the surface of an aqueous subphase was investigated. The monolayers were transferred onto mica substrates using the Langmuir–Blodgett method and examined by atomic force microscopy. Analysis of the monolayer compression isotherms and AFM images showed that the adsorption of CMCD on the cationic Langmuir lipid monolayer is accompanied by the formation of supramolecular ensembles of similar morphology regardless of the concentration of the added oligosaccharides.

脂质单分子层表面\({\beta}\) -羧甲基环糊精络合物的形成特征
在本研究中,研究了\(\beta\) -羧甲基环糊精(CMCD)与水亚相表面由电中性和阳离子脂质混合物组成的单分子层的相互作用。使用Langmuir-Blodgett方法将单层转移到云母衬底上,并用原子力显微镜检查。单分子层压缩等温线和原子力显微镜图像分析表明,无论添加的低聚糖浓度如何,CMCD在阳离子Langmuir脂质单分子层上的吸附都伴随着形态相似的超分子体系的形成。
