　　美国科学家研制出一种体积微小、具有靶向抗癌功能的“纳米盘”，将其植入人体内，可以利用生物纳米技术杀死癌细胞，无副作用。

　　这种抗癌新法现阶段已取得实验室成功。

　　体积微小

　　这种名叫“纳米盘”的新型生物纳米材料是一种高分子聚合物，外形呈圆形，带有磁性。

　　“纳米盘”直径只有100万分之一米，厚度约为600亿分之一米。由于体积微小，它们可以穿行于人体组织细胞中。

　　实验室测试证明，纳米盘可以破坏癌细胞细胞膜，使癌细胞自行死亡。

　　《科学美国人》月刊11月29日援引哈佛大学工程与应用科学学院生物工程教授戴维·穆尼的话报道：“(研究展示了)工程学方法在免疫学应用中的威力。”

　　这项研究由哈佛大学免疫学和生物工程学研究人员主持。研究成果11月29日发表在英国《自然材料》月刊网络版。

　　精确打击

　　“纳米盘”由铁镍合金制成，具有磁性，放置在磁场中时会因引力作用而移动。

　　研究报告说，“纳米盘”具有靶向抗癌功能，如果提供正确的磁场导向，它们就能准确找到癌细胞，将其消灭。

　　研究报告作者之一、美国阿尔贡国家实验所研究员埃琳娜·罗兹洛瓦说，在实验室测试中，把“纳米盘”置于低磁场环境10分钟，就足以消灭90%的癌细胞。

U.S. scientists have developed a small volume with a targeted anti-cancer function of the "nano-plate", will be implanted in the human body can make use of bio-nanotechnology to kill cancer cells, no side effects.

The new law has been made at this stage of this cancer laboratory success.

Small volume

This is called "nano-disk" of the new bio-nano-materials is a polymer, rounded shape, with magnetic.

"Nano-disk" ten-thousandth of a diameter of only 100 meters, thickness of about 600 billionths of a meter. As the size of small, they can walk through on the human tissue cells.

Laboratory tests proved that nano-plate can destroy cancer cell membrane, so that cancer cells die on their own.

"Scientific American" magazine November 29 quoted at Harvard School of Engineering and Applied Science Daiweimuni professor of biological engineering, then reports: "(Research shows) method in engineering applications, the power of immunology."

The study was conducted by Harvard University's immunology and bio-engineering research officer. November 29 studies published in the United Kingdom the "natural materials" magazine online edition.

Precision strikes

"Nano-plate" by iron-nickel alloy, with magnetic when placed in a magnetic field due to gravity and movement.

The research report said, "nano-plate" has targeted anti-cancer function, if provided the correct magnetic field orientation, they can accurately find the cancer cells, its elimination.

Author of the study, a research fellow at the U.S. Argonne National Laboratory Elena Na Luo Zi Luowa said that in laboratory tests, the "nano-disk" in low-magnetic field for 10 minutes is enough to eliminate 90% of the cancer cells .
