  • Water soluble fluorescent quantum carbon dots
    Patent number: 8357507
    Abstract: The present invention relates to the water soluble self fluorescent quantum carbon dots (C-dots). These C-dots are isolated from carbon soot in one embodiment a wax soot solvent washed and isolated from other larger material by filtration such as by membrane filtration. The C-dots can be varied in their color by change of their size and by the amount of oxidative groups' position on each C-dot.

  • WATER SOLUBLE CONCENTRIC MULTI-WALL CARBON NANO TUBES
    Publication number: 20080213367
    Abstract: The present invention relates to water soluble carbon nano tubes (WSNT) which have been made function by functionalizing with carboxylic acid groups. The carbon nano tubes are isolated from hydrocarbon wax soot and then functionalized by oxidation treatment with an oxidizing agent. The WSNT can contain a pharmaceutical composition for release by a biological degradation agent of the WSNT for example E coli.
