AbstractThe development of natural or synthetic polycations able to interact with nucleic acids and condense them into nanoparticles known as polyplexes, faces several unresolved challenges at the cellular level. Key issues include the intracellular trafficking of polyplexes, the endosomal escape and the release of nucleic acids into the cytosol, which are considered major bottlenecks for efficient protein expression.

AbstractClick to copy section linkSection link copied!Alginates aremarine polysaccharides known for their ability to selectively bind calcium ions and form hydrogels. Theyare widely used in biomedical applications but are challenging to produce as nanogels. Here we introduce a self-assembly route to create stable alginate-based nanogels under near-equilibrium conditions.
