Abstract: This document provides derivatized C60 molecules (e.g., C60-serinol) and methods and materials for using derivatized C60 molecules (e.g., C60-serinol) to reduce radiation injury. For example, methods and materials for using derivatized C60 molecules (e.g., C60-serinol) to reduce, prevent, and/or mitigate radiation injury (e.g., radiation induced oxidative stress and/or DNA damage) to cells (e.g., human cells) or to a mammal (e.g., a human) during, for example, outer space missions are provided.

Abstract: In various embodiments, the present disclosure describes fullerene derivatives that are capable of photocatalytically generating reactive oxygen species in the presence of ultraviolet and/or visible light. In some embodiments, the fullerene derivatives are aminofullerenes containing a plurality of amine-terminated moieties covalently bonded to the fullerene cage. The fullerene derivatives may optionally be covalently bonded to a substrate surface for use in photocatalytic disinfection systems for removing various contaminants including, for example, bacteria, viruses, protozoa and chemical pollutants. Methods using the present fullerene and aminofullerene derivatives in various purification processes are also described herein.

Abstract: A method of removing metal impurities from carbon nanotubes includes treating carbon nanotubes with distilled bromine in a substantially oxygen- and water-free atmosphere and then removing the distilled bromine from the carbon nanotubes. Purified carbon nanotubes having an iron content from about 2.5 to about 3.5 by weight that are substantially free of derivatization at the ends and defect sites are made available via this method.

Abstract: Nanostructures comprising radioisotopes and/or metals are provided. More particularly, in some embodiments, nanostructures comprising radioisotopes and/or metals, methods of their synthesis, and their use in cancer imaging and therapy are provided.
