最近,中国科学技术大学化学与材料科学学院、合肥微尺度物质科学国家实验室曾杰教授课题组与厦门大学分子影像暨转化医学研究中心刘刚教授合作,在金属合金纳米材料的可控合成及其生物和催化应用方面取得重要进展.研究人员通过共还原的途径,首次在溶液中合成出五角星形金铜合金纳米晶体,并使用新型材料成功治愈小鼠乳腺癌.同时,由于该新型材料具有大量的高指数晶面,它在对硝基苯酚还原反应中展现了不俗的催化性能,该工作7月在线发表于Nature Communications(doi:10.1038/ncomms5327).一般来说,如果光的波长在近红外区(700~900 nm),光在生物组织内穿透深度达到最大值.而对于金属纳米材料而言,它们在紫外-可见-近红外区具有等离基元共振现象,可以在这些区域有很强的光吸收和光热转化能力.光热产生的高温可以杀死癌细胞,从而实现肿瘤的无创治疗.因此,从理论上讲,采用该办法治疗人类肿瘤是可行的.与放射治疗、化学药物治疗等传统方法相比,该疗法无需
Recently, the University of Science and Technology of China, Faculty of Chemistry and Materials Science, Hefei National Laboratory for Microscale Materials Science and Technology Professor Zeng Jie and Xiamen University molecular imaging and Translational Medicine Research Center, Professor Liu Gang cooperation in the synthesis of metal alloy nanomaterials and their Biological and catalytic applications made important progress.The researchers through the co-reduction pathway, the first synthesis of pentagonal star gold-copper alloy nanocrystals in solution, and the use of new materials to successfully cure mice with breast cancer.At the same time, the new material has A large number of high index crystal planes, which exhibit good catalytic performance in the reduction of p-nitrophenol, was published online in Nature Communications (doi: 10.1038 / ncomms5327) in July. In general, In the near-infrared region (700-900 nm), light penetrates to a maximum depth in biological tissues, whereas for metallic nanomaterials they have plasmon resonance in the UV-VIS-NIR region, The region has a strong light absorption and photothermal conversion ability.High temperature generated by photothermal can kill cancer cells in order to achieve noninvasive treatment of the tumor.Therefore, In theory, it is possible to treat human tumors using this approach, and compared to traditional methods such as radiotherapy and chemotherapeutic treatments,
