Chemists create 'Superbowl' molecule; May lead to better health

...ou're trying to capture certain molecules and hold them until they're ready for release, the researcher says. Superbowl molecules are similar in function to buckyballs, the experimental soccer-ball shaped molecules also known as fullerenes (C60), which also show promise for drug delivery and other useful...

DNA Molecules Used To Assemble Nanoparticles

...rugs, and contrast agents, and the ability to link them together quickly and easily in many different ways would enable a clinic to offer 25 different "flavors" of dendrimer with only ten synthesis steps, Baker said. Baker foresees a nanoparticle cluster in which a single dendrimer carries three single-s...
