New Nano Material to be Applied in Cancer Treatment

The widely known song for children : "Twinkle, twinkle little star, how I wonder what you are" has inspired a research team led by Zongjie, a professor in University of Science & Technology of China. By combining gold and copper, the team has invented a "five-pointed star" shape alloy nano material that possesses both excellent optical property and catalytic property. The research result has been published on Nature.

Alloy nano material is so expensive that it is difficult to be applied in various fields. Despite its good performance and inexpensive price, copper is unstable in nano size and is easy to be oxidized, so it is still not a perfect for the vast application. The research group lead by Zeng adopted reduction on both gold and copper to make a "five-star shape" alloy material that possesses both excellent optical property and catalytic property.

According to iAbrasive report, the "nano star" new material is a nano crystalline gold and copper alloy pentagonal symmetry which has a strong capacity to absorb and transfer light in near infrared region. Researchers injected the material in a mouse that has breast cancer, and irradiate around the cancer. Nano crystalline then adsorbed the infrared and converted into heat The high temperature can kill cancer cells. By adopting the method, the mouse was cured of breast cancer in four days.

Meanwhile, the new nano material has many edges and corners, which take on extraordinary performance. Since its good property and cost-effective price, and it is easy to make, the glittering "nano star" is anticipated to be widely used in bio treatment (such as cancer treatment) and catalytic field.
