How nanotechnology helps mRNA Covid-19 vaccines work
While the first two Covid-19 vaccines relying on messenger RNA technology speed toward regulatory approval in the U.S., it’s worth remembering the vehicle that gets them where they need to go in the body.
Lipid nanoparticles are the fatty molecular envelopes that help strands of mRNA — the genetic messenger for making DNA code into proteins — evade the body’s biological gatekeepers and reach their target cell without being degraded. They are enabling some of the most advanced technologies being used in vaccines and drugs.
