Cyclodextrin (CyD)-based nanoparticles and polyamidoamine (PAMAM)\r\nstarburst dendrimers (dendrimers) are used as novel carriers for DNA and RNA. Recently,\r\nsmall interfering RNA (siRNA) complex with -CyD-containing polycations (CDP) having\r\nadamantine-PEG or adamantine-PEG-transferrin underwent a phase I study for treatment\r\nof solid tumors. Multifunctional dendrimers can be used for a wide range of biomedical\r\napplications, including the interaction and intracellular delivery of DNA and RNA. The\r\npresent review will address the latest developments in dendrimer conjugates with\r\ncyclodextrins for siRNA delivery including the novel sustained release system.
