Researchers at UCSB attached polymeric nanoparticles to red blood cells and found that it increased the lifespan of the nanoparticles. This could potentially lead to a better method of delivering drugs via the body's own circulatory system.
Quoting the research team's leader, Samir Mitragotri: "Using red blood cells to extend the circulation time of the particles avoids the need to modify the surface chemistry of the entire particle, which offers the potential to attach chemicals to the exposed surface for targeting applications."
