Background: Genetic drugs have aroused much attention in thepast twenty years. RNA interference (RNAi) offers novel insights intodiscovering potential gene functions and therapies targeting genetic diseases.Small interference RNA (siRNA), typically 21-23 nucleotides in length, canspecifically degrade complementary mRNA. However, targeted delivery andcontrolled release of siRNA remain a great challenge.

Methods: Different types of lipid-based delivery vehicleshave been synthesized, such as liposomes, lipidoids, micelles, lipoplexes andlipid nanoparticles. These carriers commonly have a core-shell structure. Foractive targeting, ligands may be conjugated to the surface of lipid particles.

Results: Lipid-based drug delivery vehicles can be utilizedin anti-viral or anti-tumor therapies. They can also be used to tackle geneticdiseases or discover novel druggable genes.

Conclusion: In this review, the structures of lipid-basedvehicles and possible surface modifications are described, and applications ofdelivery vehicles in biomedical field are discussed.
