CAMBRIDGE, Mass.--(BUSINESS WIRE)--Alnylam Pharmaceuticals, Inc. (Nasdaq: ALNY), a leading RNAi therapeutics company, together with collaborators at the Massachusetts Institute of Technology (MIT), announced today the publication of new paper describing discovery of “core-shell” nanoparticles for systemic delivery of RNAi therapeutics. The core-shell nanoparticles were generated using a high-throughput polymer synthesis strategy and screened for intracellular delivery applications including siRNA delivery. These findings, published in the Proceedings of the National Academy of Sciences (Siegwart et al., PNAS, 2011, doi: 10.1073/pnas.1106379108) allow for the development of novel nanoparticles that have optimal chemical and physical properties for effective intracellular delivery of RNAi therapeutics.
