Specialized services with Cyclodextrins

Native cyclodextrins (CDs) are relatively small and simple molecules which may lead to highly involved structures with exotic properties. They are formed by 6 (α-CD), 7 (β-CD) or 8 (γ-CD) glucopyranoside rings with primary and secondary hydroxyl groups that can be specifically modified for specific purposes.

Native and modified CDs are typicall employed to host small molecules or molecular groups within their hydrophobic cavity leading to complexes with 1:1 stoichiometry but cyclodextrin nanoaggregates can also encapsulate more complex structures.

Additionally, second or higher order supramolecular inclusion complexes based on cyclodextrins may be formed.

The aggregation of such complexes may lead to interesting structures that can compartmentalize forming functionalized liposome-like structures in solution and also adsorb to polar-nonpolar interfaces forming thin films.

We have a large experience in the study of this kind of systems both experimentally and also by computational calculations. Take a look to Cyclo-lib, an open-access database of Molecular Dynamic simulations of cyclodextrins developed by our scientific team: http://cyclo-lib.mduse.com/
