Abstract:
The delivery of small interfering RNAs (siRNAs) is a promising approach to silencing gene expression aimed at treating infections, cancer, neurodegenerative diseases and various other disorders. Recent progress in this area has been achieved with nanodevices possessing multiple properties and assembled with new, biodegradable, synthetic polymers and polysaccharides. Different synthetic routes and multiple strategies, such as multilayer systems and stimuliresponsive polymers, have been developed to attain high efficiencies. This review covers the most important, promising and successful approaches to improve siRNA delivery. It is a concise report on multiple strategies employed, including cell-specific delivery coupling ligands or antibodies with nanodevices to improve siRNA efficiency and specificity.

siRNA - Small Interfering RNAs
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...

RNA Interference
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
