Cyclodextrin molecules construct load, delivery and controlled release carrier, the carrier used the same as including inorganic materials, organic synthetic polymer materials and natural polymer materials. The load in drug delivery and delivery system, and the carrier itself often has certain drug load, transport and release properties, introducing cyclodextrin units not only can. Complexation lifting load of drug molecules through the package, and play the role of sustained release, and can significantly reduce the drug load, the cytotoxicity of delivery and delivery system, improve its biological compatibility. In addition, due to the presence of the support, system load, transport and molecular release drugs at the same time, can also load DNA or siRNA, even the targeted delivery of drug molecules ligand, so it can be a variety of effective and targeted delivery to the lesion, and control of slow release, play together, Improve the therapeutic effect
For example, scientists through non covalent interactions will be full (6- deoxy -6- thiol) - cyclodextrin immobilized on gold nanoparticles, the adamantyl and beta cyclodextrin units of host guest interaction, build the anticancer drug cisplatin delivery system. The study found that the gold nanoparticles on the beta cyclodextrin coverage the density of up to 210 beta cyclodextrin / gold nanoparticles, and 150 betacyclodextrin unit to drug delivery, drug loading amount is quite considerable.
