Gold-Coated Carbon Nanotubes for Biomedical Applications


Technology #06-11


The invention proposes a novel use of Gold coated Carbon Nanotubes (CNT) for bio-compatibility


Carbon nanotubes (CNT's) are known to have particular optical qualities that make them interesting for possible biomedical applications. Specifically, the CNT's are very responsive to light in the near-infrared range (700 – 1110 nm wavelength). Biological systems, including the human body, are transparent to light in this wavelength range. Because of the optical responsiveness of CNT’s, there are possibilities for using the CNT’s for medical applications, such as medical imaging, and treating cancer. But CNT’s are not very bio-compatible, and for this reason, they are not used inside living bodies. Gold however is proven to be bio-compatible, and is one of the few metals approved for use in the human body for the FDA.




In-vivo & In-vitro imaging of biological matter and subjects using bio-compatible CNT's.




The advantages are that via the combination of gold coating over CNT, the improved optical responsiveness of CNTs can be utilized while being deemed bio-compatible via the use of the gold coating.




By combining the bio-compatibility of gold with the optical responsiveness of CNT’s, significant possibilities for biomedical applications become practical. Gold can be functionalized, so that the surface of the gold coated CNT’s can be a foundation for various biological targeting agents, such as antibodies, or DNA ligands. Once the gold coated CNT’s are in place in the body, light can be used to excite the Gold CNT’s to produce tumor-killing photothermolysis, and results from medical imaging become sharper using the gold CNT’s as a contrast agent. The invention is patent pending, and the publication number of the application is 2010/0189650
