Abstract: A method for synthesizing carbon nanotube drug carriers and the carbon nanotube drug carriers are disclosed. Initially, carbon nanotubes, nitric acid, and sulfuric acid are mixed to oxidize carbon nanotubes in a first mixture. The oxidized carbon nanotubes are then extracted from the first mixture. The oxidized carbon nanotubes and monohydrated citric acid are mixed to synthesize carbon nanotubes grafted with poly(citric acid) in a second mixture. The carbon nanotubes grafted with poly(citric acid) are then extracted from the second mixture. The carbon nanotubes grafted with poly(citric acid) and 4-(dimethylamino)pyridine are dissolved in anhydrous dimethylformamide in a third mixture. Next, a mixture that comprises a drug is added to the third mixture to synthesize the carbon nanotubes grafted with poly(citric acid) and the drug in a fourth mixture. Then, the carbon nanotubes grafted with poly(citric acid) and the drug are extracted from the fourth mixture.

Abstract: A method to prepare new morphologies, especially vesicle-type, of carbon nanotubes (CNT) by supramolecular interactions between them and dendritic or linear-dendritic polymers and copolymers. Due to their water solubility, high functionality and unique properties, the prepared hybrid nanomaterials have excellent applicability in different fields especially in nanomedicine in comparison with usual CNTs.

Abstract: This invention provides the synthesis of biocompatible and high functional hybrid nanomaterials consisting of pseudorotaxanes, pseudopolyrotaxanes, rotaxanes, polyrotaxanes, nanoparticles and quantum dots (QDs). The molecular self-assembly of hybrid nanomaterials lead to the formation of nano-objects with different shapes such as core-shell, spindle-like or necklaces. Due to their well-defined molecular self-assemblies, carbohydrate backbone, high functionality and several types of functional groups together with the high luminescence yield, thermal and physical properties and synthesized hybrid nanostructures were recognized as promising candidates for a wide range of applications.

Abstract: The various embodiments herein provide a hyper branched polyester and a method of synthesizing the same. The embodiments herein also provide a method of encapsulating a drug into the void spaces of the polymer to act as a drug delivery system. The hyper branched polyester mer comprises an acidic moiety and an alcoholic moiety. The acidic moiety is citric acid monohydrate. The alcoholic moiety is glycerol. The acidic moiety and the alcoholic moiety are randomly arranged in the hyperbranched polymer. The method comprises of heating the mixture of citric acid and glycerol at temperatures of 90 to 150° C. by constant stirring for different time periods. In the method of encapsulation, the drug solution is drop-wise added to polymer solution at 37° C. by constant stirring for 24 h.
