摘要： There is provided a process for preparing alloy nanoparticles having a desired size. The process comprises a combination of co-reduction of metal salts in the presence of a reducing agent, and multi-step seeded growth synthesis. Also provided is a material which comprises alloy nanoparticles made of at least two metals. A mean diameter of the particles of the material is between about 30 nm and 200 nm as measured by transmission electron microscopy (TEM), and the particles have a coefficient of variation smaller than about 15%.

摘要： The present disclosure relates to a nucleic acid delivery composition comprising a coated chitosan-based polyplex, wherein the coated chitosan-based polyplex comprises: a chitosan; an isolated nucleic acid; and an additional polyelectrolyte. The coated chitosan-based polyplex has an initial or a final molar ratio of amine groups of chitosan (N) to phosphate groups of the nucleic acid (P) to carboxyl groups of the additional polyelectrolyte (C) (N:P:C), wherein the N has a value between about 1.0 and about 10.5, the P has a value between about 1.0 and about 2.0 and the C has a value between about 1.0 and 10.5.
