Fullerenes and Buckyballs
|
Fullerenes or buckyballs are carbon (C60) molecules having a cage-like structural arrangement of 60 or more atoms. The surface of the fullerene sphere consists of a mixture of twelve rings with five carbon atom members with the balance of rings having six carbon atoms. The name for these materials was derived from Buckminster Fuller due to similarity between the molecules and the geodesic dome structures that Fuller invented. Gas or liquid molecules can be trapped inside the buckyball, providing a potential mechanism for drug nanoencapsulation and delivery. Products & Services

Mass spectrometers separate ions by their mass-to-charge (m/z) ratios. They are used to identify compounds by the mass of one or more elements in the compound. They are also used to determine the isotopic composition of one or more elements in a compound.
