Research is being conducted on drug delivery systems for RNA therapeutics, with various approaches being explored, including the use of nanomaterials and artificial intelligence. Some studies are focused on overcoming delivery barriers and optimizing systems, such as lipid-nanoparticle delivery systems, to enhance the effectiveness of RNA therapeutics. Startups, including one called Axelyf, are also working to develop and advance RNA delivery technologies, with some reporting seed funding to support their efforts.
