美国物理学家组织网 2011 年 2 月 22 日报道了美国宾夕法尼亚大学医学院的研究人员研制出了一种可选择性杀灭癌细胞的药物，有可能为肝癌的治疗打开一个新窗口。在试管和小鼠实验中，他们将一种化学药物 C6- 神经酰胺包裹在分子大小的小泡中作为一种抗癌剂，成功实现了抑制癌细胞增长并最终促其死亡的目的。 C6- 神经酰胺是鞘脂类的中间代谢产物，天然存在于人体细胞质膜中，具有控制细胞新陈代谢、促使细胞衰老的能力。但是，自然情况下人体内的神经酰胺在癌细胞中的含量过低，并不能起到杀灭的作用。脂质的特殊性质也决定了神经酰胺并不能像普通药物那样能直接被输送到病灶区域。为了解决这一问题，研究人员才想出上述“药物胶囊”的主意。借助纳米技术，研究人员让神经酰胺套上了这种分子大小的蛋白质薄膜“外套”，这才使其相容性质得到了改变。 动物实验结果显示，这种药物能有效杀死癌细胞而不伤及正常细胞，在小鼠实验中已被证明能有效治疗乳腺癌和黑色素瘤。当其与常用抗癌剂结合使用时也并未发现毒副作用。 研究人员发现，在针对肝癌细胞的实验中，该药物也能选择性诱导肿瘤细胞死亡。在对患有肝癌小鼠的实验中，该药封闭了为肿瘤生长提供营养的血管。而营养的缺乏会使细胞组织中产生更多的神经酰胺，并最终导致癌细胞死亡。肝癌是世界上第五大常见癌症，晚期患者存活率不到百分之五，极具危害性，目前临床上一般多采取手术、放化疗以及肝移植疗法，但治愈率较低。 C6- 神经酰胺除了对肝癌、乳腺癌、黑色素瘤有明显抑制作用之外，对于急性髓系白血病以及结肠癌等也有效。但是并非单独使用，而是与其他抗癌药物联合使用。 2011 年元月 27 日，中国药科大学的 ZHU Q-Y 等人在《 Cell Death and Disease 》也发表了 C6- 神经酰胺应用于抗肿瘤研究结果（ Q-y Zhu ， et al.

受国外杂志邀请在Recent Patent on Nanotechnology 发了一篇综述。对于全球纳米粉体材料的专利发展做了一个评论。有朋友问过，纳米技术到底有那些应用。这篇文章应该可回答稍全一些。 Development and Applications of Nano-Powder Patents ---- A Review in Patents Abstract A thorough review on the patents in the applications of nano-powder technology shows that research work in this technical field is growing stronger, as indicated by a rapid increase in the number of independent patents in relevant topics. This also indicates ever increasing and continuous interests on the nano-podwer technology even after 15 years of dynamic global nanotechnology development. The review on the patents in the nano-powder area shows that the use of specialized databanks is recommendable and beneficial in providing the researchers in this technical community an updated, systematic and rapid reference in furthering new development and expansion of this vital nanotechnology field. 陆续有国内外的朋友要求看此文全文，全文可以在杂志网站看到。

在很长一段时间内，美国一直在与前苏联争夺着外层空间的霸主地位。今天，美国再次卷入了一场别开生面战役：国际新兴纳米技术领域主导地位的较量，即在原子尺度上研究物质，进而研发新型材料。参加两周后即将开幕的 2010中国(上海)国际纳米展览会 的代表将更为清楚地认识到，中国将紧紧跟随美国的脚步，并最终成为纳米技术领域的领跑者。 中国可以赶超美国并最终超越其他所有竞赛者并非天方夜谭：中国在纳米技术领域的投入在 过去十年中每年以20% 的速度增长。现在，中国在纳米技术领域的文章数量比任何其他国家都要多，而且近年来，中国在这一领域获得的专利许可数量已经超过了美国。美国在纳米技术领域的投入 每年以18%的速度增长 ，照此看来，尽管美国在投入方面依旧会处于领先地位(2008年的研发投入是57亿美元)，但是其他竞赛者，特别是中国，正在高速追赶。也正是由于这个原因，在 总统科技顾问委员会给美国总统奥巴马的一份报告 中指出，美国应加大对纳米技术领域的投资。 纳米技术具有广泛的应用，包括医学、军事、环境整治、工程以及生活消费品生产等等领域，据测截至2012年产业效益可以达到2万亿。这也是为什么各国在这个领域内投入如此之高，而且在竞争中如此激烈角逐的原因，每个国家都力争在这场战役中脱颖而出。 中国已经在纳米技术领域取得了一些成绩，例如纳米扬声器，去年 卫报 报道的一个只有一毫米厚的音频系统。然而对于中国制造的纳米产品的质量问题，业内专家还是存在一定的质疑。 英国纳米技术协会 的Mark Morrison博士指出，来自中国科研机构的同行评审学术论文的引用次数要远远少于来自美国、日本的欧盟国家的。他还 指出 了这一行业中健康、安全以及生产标准的重要性：我们(英国)恪守标准，也许这看起来很枯燥，但是它对于纳米技术的发展以及环境、健康和安全方面的研究是至关重要的。 不可否认的是，适当的安全标准和质量控制措施对于产品安全投放到市场是至关重要的。 去年八月 在中国某家纳米技术生产工厂里两位年轻女性的死亡以及五例致病案例为行业安全生产规范敲响了警钟。尽管没有确凿的证据表明死者的死因是其所接触的纳米颗粒所致，但是据调查工厂内并没有执行可以预防潜在伤害的标准生产安全规范。 在纳米技术领域以外，类似的案例如 婴儿奶粉中添加三聚氰胺 等事件的出现，也会加剧人们对中国纳米产品质量的怀疑。如果中国政府能够和国内的纳米科学家、科学工作者以及企业家一道，像发达国家一样切实落实并加强行业标准和规范，中国在纳米技术领域的投入将有可能得到更为丰厚的回馈。仅仅赢得竞争是不够的，关键是要摘掉不合格的帽子。 原文： China poised to take the lead in nanotechnology For many years the US was involved in a space race with the Soviet Union, a competition to see who could be the first to explore the outer reaches of space. Now, the US is embroiled in a different kind of battle: the race to dominate the emerging international industry surrounding nanotechnology, the manipulation of matter on an atomic scale to develop new materials. As will become clear to delegates at the Nanotech China meeting in Shanghai in just two weeks, China has positioned itself hot on the heels of the US and is poised to take the lead in the race for domination of the industry. Chinas ability to catch up with the US and pass all other participants in the race should not come as a surprise: its investment in nanotech has increased by 20% every year for the past decade . As a result, China now produces more papers on nanotech than any other country, and it has surpassed the US in recent years in the number of nanotech patents granted. At the same time, investment in nanotech in the US grew at a rate of 18% per year , with the result that, although the US still leads the way in terms of investment (with Research and Development investments of $5.7 billion in 2008), the rest of the world, and especially China, is rapidly catching up. This is the basis of a report to President Obama from the President's Council of Advisors on Science and Technology calling for increased investment in the sector. Nanotechnology, which has very broad applications including uses in medicine, the military, environmental management, engineering and the manufacture of consumer goods, is predicted to represent a two-trillion-dollar industry by 2012. This explains the high levels of investment in this sector and why countries are jostling for the lead in the race, as each of them strives for an edge in global competitiveness. China has already had some success in the area of nanotech; for example, the nano-speaker, a one-millimetre-thick audio speaker reported in the Guardian last year. However, this success is not without controversy, and there have been some questions from industry experts regarding the quality of nanotech products coming out of China. Dr Mark Morrison of the Institute of Nanotechnology in Scotland has made the point that Peer-reviewed scientific papers from Chinese institutes are cited far less than those from US, Japan and EU. He also pointed to the importance of health and safety as well as manufacturing standards for the industry: We are strong in standards, which may seem boring, but is critical to the development of nanotechnology and environment, health and safety research. It is undeniable that appropriate safety regulations and quality control procedures will be critical for products to reach the market. The deaths of two young women and illnesses of five others in August last year , while working in a Chinese nanotech manufacturing facility, strengthen the need for caution and tight regulations in the industry. However, the cause of death has not been definitively attributed to the nanoparticles the women were exposed to, and standard manufacturing safety practices that could have prevented any harm were not being observed in the factory. Stories such as this and other, non-nanotech-related scandals like the melamine in baby milk incident will serve to foster scepticism and questions regarding nanotechnology products emerging from China. If the Chinese government, working together with Chinese nanotechnologists, scientists and business leaders, could implement and enforce standards and regulations similar to those established elsewhere in the developed world, its investment in the sector will be far more likely to bear fruit in the future. It is not enough just to win the race; one must also avoid disqualification. Thin-film nano speaker over the screen of an IPod:
Nin men hao! This is Stewart Dods from LiwenBianji. My Chinese name is 丁丁 Previously, we have posted helpful advice for Chinese authors wishing to report their research in English language journals. Starting next week, we are going to hold a week-long event focused on a specific field of science. The events will include interesting articles and interviews, recent news and hot papers and reviews of the best journals to submit to and online resources. From 17th May to 22nd May we will hold our first theme week for the field of nanotechnology. Key items to watch out for during this week include: - China poised to take the lead in nanotechnology - An interview with Mark Reed the Chief Editor of IOP Nanotechnology - Nanotechnology journals review To celebrate the forthcoming nanotechnology theme week I leave you with the nanobamas. The portraits each contain about 150 million carbon nanotubes and are barely visible to the naked eye.The nanobamas were created by Professor John Hart and his team at the Department of Mechanical Engineering, University of Michigan.
