Able to generate active oxygen to kill cancer cells.

Substance - Kyoto 19, these groups Assistant Professor Murakami (iCeMS) Institute for Integrated Cell can generate active oxygen with the "carbon nanotube" carbon fiber which has attracted attention as a new material, to kill cancer cells I announced that it had succeeded. In the near future, published in the Journal of the Chemical Society of the United States. Can lead to the development of a new cancer treatment method that is expected.
And shed light on the carbon nanotube, the Group noted that the active oxygen heat and generate toxic for organisms. I was subjected to human lung cancer cells to succeed in diffusing in water by the carbon nanotube, the good cholesterol in addition, the solution was removed to the culture dish. Shed further near-infrared for 10 minutes, and to generate heat and active oxygen, 45% of cancer cells that were killed after 24 hours.
Is expected to have not known such as the impact on the human body, but many problems in practical use, and lead to the development of new cancer therapies. Assistant Professor Murakami talking point "that kill cancer cells in both the thermal and reactive oxygen unusual" and. 45% of cancer cells The fact that he died in more than one day feel like a terrible thing. For practical use, but further research would be needed, it is better to go with a new method of cancer treatment.

京都大物質－細胞統合システム拠点（ｉＣｅＭＳ）の村上助教らのグループは１９日、新素材として注目されている炭素繊維「カーボンナノチューブ」を使って活性酸素を発生させ、がん細胞を死滅させることに成功したと発表した。近日中に、米化学会誌に掲載する。新たながん治療方法の開発につながることが期待されるという。
　グループは、カーボンナノチューブに光を当てると、熱と生物にとって有毒な活性酸素が発生することに着目。カーボンナノチューブに、善玉コレステロールを加えることで水中で拡散させることに成功し、その溶液を培養皿に取り出したヒトの肺がん細胞にかけた。さらに近赤外線を１０分間当て、熱と活性酸素を発生させると、２４時間後にはがん細胞の４５％が死滅したという。
　人体への影響などは分かっておらず、実用化には課題も多いが、新たながん治療法の開発につながると期待される。村上助教は「熱と活性酸素の両方でがん細胞を死滅させている点が珍しい」と話している。がん細胞の４５％が一日余りで死滅したというのは凄いことのように感じますね。実用化には、更なる研究が必要でしょうが、がん治療の新しい手法となっていくと良いですね。
