“…The most common cross-linkers are epichlorhydrin and citric acid [52,[55][56][57]. The water-insoluble cyclodextrins today are used as a solid phase to remove pollution from solutions and used in analytical chemistry [58][59][60][61]. The oral usability of solid, water insoluble, cyclodextrin polymer as a microsize-controlled drug delivery system is a promising tool for the formulation of controlled drug delivery systems.…”

Cyclodextrins are widely used excipients, composed of glucopyranose units with a cyclic structure. One of their most important properties, is that their inner cavity is hydrophobic, while their surface is hydrophilic. This enables them for the complex formation with lipophilic molecules. They have several applications in the pharmaceutical field like solubility enhancers or the building blocks of larger drug delivery systems. On the other hand, they have numerous effects on cells or biological barriers. In this review the most important properties of cyclodextrins and cyclodextrin-based drug delivery systems are summarized with special focus on their biological activity.

“…Differences between sampling locations were more pronounced with methyl-β-cyclodextrin and 2-hydroxypropyl-β-cyclodextrin as hosts, which are both more soluble and more hydrophobic than the unsubstituted β-cyclodextrin [49]. Although benzenederived aromatic compounds form strong host-guest complexes with all β-cyclodextrin derived compounds investigated herein, including β-cyclodextrin [50], methyl-β-cyclodextrin [51], and 2hydroxypropyl-β-cyclodextrin [52], the enhanced solubility, combined with the greater hydrophobic character of methyl-βcyclodextrin, promote the stronger complexation of the aromatic guests [53]. This, in turn, results in more sensitive changes in the fluorophore emission signal upon introduction of the BTEXC guests and competitive displacement of the fluorophore from the cyclodextrin cavity.…”

Fluorescence-Based Detection of Benzene, Toluene, Ethylbenzene, Xylene, and Cumene (BTEXC) Compounds in Fuel-Contaminated Snow Environments

Reported herein is the sensitive and selective cyclodextrin-promoted fluorescence detection of benzene, toluene, ethylbenzene, xylene, and cumene (BTEXC) fuel components in contaminated snow samples collected from several locations in the state of Rhode Island. This detection method uses cyclodextrin as a supramolecular scaffold to promote analyte-specific, proximity-induced fluorescence modulation of a high-quantum-yield fluorophore, which leads to unique fluorescence responses for each cyclodextrin-analyte-fluorophore combination investigated and enables unique pattern identifiers for each analyte using linear discriminant analysis (LDA). This detection method operates with high levels of sensitivity (sub-micromolar detection limits), selectivity (100% differentiation between structurally similar compounds, such as ortho-, meta-, and para-xylene isomers), and broad applicability (for different snow samples with varying chemical composition, pH, and electrical conductivity). The high selectivity, sensitivity, and broad applicability of this method indicate significant potential in the development of practical detection devices for aromatic toxicants in complex environments.
