Context: RNA interference (RNAi)-based therapeutics rely upon safe and efficient delivery of small interfering RNA (siRNA) molecules.
Objective: This review explores various dimensions of RNAi with emphasis on the development of nanoparticle-based delivery vectors for safe and efficient siRNA delivery.
Methods: An exhaustive database search has been done regarding studies done to investigate the potential of siRNA delivery employing nanoparticles has been cited in the present review.
Results and conclusion: With the current challenges, there is a need for collaborative work allowing for the successful development of nanoparticle/siRNA complexes as health-promoting biotherapeutics.
Keywords: RNA interference; gene silencing; nanoparticles; small interfering RNA; transfection.
