  • Detail

The new material "nano star" invented by the University of science and technology of China cures malignant tumors in mice in 4 days. Researchers injected this material into mice with breast cancer, irradiated the tumor with near-infrared laser, and killed cancer cells with the local high temperature generated. With this therapy, mice successfully recovered from the tumor in only four days. For example, the use of high wear resistance, twinkle and twinkle, and the sky is full of small stars, is the first well-known nursery rhyme, but it has inspired the research inspiration of the research group of Professor Zeng Jie of Hefei National Laboratory of micro scale material science (Preparatory) of University of science and technology of China and the school of chemistry and materials science. The researchers then invented a star shaped nano material, which combines both advantages and disadvantages, and has excellent optical properties and catalytic properties

the new material of nano star invented by Professor Zeng Jie's research group is a high branched Pentagram gold copper alloy nanocrystal with five fold twins. This new material has a strong ability of light absorption and photothermal transformation in the near-infrared region. Researchers injected this material into mice with breast cancer, and irradiated the tumor with near-infrared laser at the place where the swelling cannot slip. In addition to adjusting according to the Convention, the local high temperature produced was used to kill cancer cells. With this therapy, mice successfully recovered from the tumor in only four days

at the same time, because this Pentagram shaped nano material has rich edges and corners and unique high index crystal planes, it performs well in the catalytic reaction of nitro reduction and can save images in the form of image files. According to the analysis of catalytic reaction kinetics, the catalytic performance of Pentagram shaped gold copper alloy nanocrystals with a size of less than 70 nm is better than that of the traditional 5 nm pure gold catalysts with the same quality. This new material is expected to be applied in the fields of biological diagnosis and treatment and heterogeneous catalysis
