笼形分子

该传感器由一段多模光纤中间插入并熔接一小段单模光纤组成，且单模光纤包层表面涂覆一层含笼形分子E的透明聚硅氧烷薄膜。

The sensor consists of a multimode fiber in which a short section of standard single-mode fiber , coated with the inclusion of cryptophane molecules E in a transparent polysiloxane film , is inserted .

β-环糊精（CD）是一种外部亲水内部疏水的笼形分子，能与疏水性分子形成包合物，增加其水溶性。

β - cyclodextrin possesses a cage-like supramolecular structure with a hydrophobic cavity and hydrophilic outside and is able to form inclusion complexes with a wide variety of hydrophobic guest molecules and then improve their solubility .
