C60 Fullerene

C60 fullerene, formally buckminsterfullerene, is a molecule built from sixty carbon atoms joined into a closed, cage-like structure resembling a soccer ball, with twenty hexagonal and twelve pentagonal faces forming a truncated icosahedron ^[3]. It is one of the allotropes of carbon, alongside graphite and diamond. The molecule was first identified in 1985 by Harold Kroto, Robert Curl, Richard Smalley, and their colleagues at Rice University, a discovery that earned the Nobel Prize in Chemistry in 1996; it was named in honor of the architect Buckminster Fuller, whose geodesic domes its shape recalls.

As a pure substance, C60 is a black solid that dissolves in some organic solvents to give a characteristic purple solution, and it is essentially insoluble in water ^[3]. Its electron-accepting cage makes it chemically versatile, and much of its appeal in research comes from its ability to interact with reactive free radicals ^[1][3].

In biology and medicine, C60 and its chemical derivatives have been investigated for a variety of properties, most prominently as antioxidants. A tris-malonic acid derivative of C60 was shown to behave like the enzyme superoxide dismutase, catalytically neutralizing the damaging superoxide radical, and it extended survival in a mouse model lacking a key antioxidant enzyme ^[1]. A widely cited 2012 study reported that C60 dissolved in olive oil and given orally to rats was not toxic and was associated with a marked increase in lifespan, an effect the authors attributed largely to reduced oxidative stress ^[2]. Reviews have since surveyed fullerenes as antioxidant, antiviral, neuroprotective, and anti-inflammatory agents and as potential carriers for delivering drugs ^[3][4].

Despite this interest, C60 remains a subject of laboratory and preclinical research rather than an approved medicine, and important questions about its long-term fate and safety in the body are unresolved; notably, solutions of C60 in oil can degrade when exposed to light ^[2][3]. It is encountered as a fine powder or crystalline solid, in oil-based preparations such as C60 in olive oil sold as a supplement, and, in research, as water-soluble chemically modified derivatives designed to improve its handling in biological systems ^[4].

Human safety data is thin. Pristine C60 appears low in toxicity in animal studies, but purity matters a lot since some fullerene derivatives can generate rather than quench radicals under light. Avoid sun exposure of the product, and be wary of unregulated sources. Long-term effects in humans are simply unknown.
