Advanced multi-lamellar vesicles transforming drug delivery across therapeutic areas
Imagine if we could wrap medication in microscopic protective capsules so smart that they travel directly to the exact location in the body where they're needed most, then release their healing payload precisely on target.
This isn't science fiction—it's the reality being created by Novasome technology, a revolutionary approach to drug delivery that's transforming how we treat diseases.
Like sophisticated cargo ships navigating biological systems to deliver medication exactly where needed
Tiny lipid bubbles so small that thousands could fit across the width of a single human hair
At their core, Novasomes are sophisticated vesicular systems—essentially microscopic, multi-layered bubbles designed to carry medicinal compounds. Their name provides a clue to their nature: "Novasome" combines "novus" (Latin for new) with "soma" (Greek for body), literally meaning "new bodies." These innovative structures were originally developed by Novavax and represent a significant evolution beyond earlier drug delivery systems like liposomes 1 .
