Process for generating multilayered particles |
摘要 |
We describe a process for generating multilayer particles comprising condensing a polymer with an oppositely charged polymer to form a particle and sequentially adding oppositely charged polymers to the particle forming at least three layers of polymers. The process is used to form a composition for delivering a biologically active compound to a cell.
