Nanoparticles: Size And Charge Matter, Science News
 









Excerpts: It's not so much what the tiny particles are made of, but how they
interact with proteins in the blood, that can determine the particles' fates as
couriers of specific treatments for diseaseBefore you trust a medical
nanoparticle, you should know what kind of riffraff it hangs out with. Larger
than a protein but much smaller than a bacterium, medical nanoparticles are
tiny, synthetic vessels that scientists design to carry drugs, genes or other
therapeutic compounds into the body. As these particles travel in the
bloodstream, proteins that glom on can dramatically affect whether the particles
will be healing or toxic.
