"NANOPARTICLES: synthesis of nanoparticles coming into focus"
Scientists are fast gaining control over the building of tiny particles, accomplishing nanoparticle synthesis in both inorganic and organic chemistries. University of Arkansas researchers here have devised a "green" chemical process that offers tight control over the size of nanoparticles and eliminates toxic by-products. And a team at the University of Michigan (Ann Arbor) is developing dendrimer-based fluorescent particles to monitor human cell damage from radiation.
