美国麻省理工学院的研究人员近日开发出一种碳纳米管传感器,把它植入皮下之后,可全年实时监测活体动物体内的分子活动,如炎症反应中产生一氧化氮(NO)的过程,或监测血糖及胰岛素水平,而无需再像传统方式那样采血检验。该研究结果发表在《自然·纳米技术》(Nature nanotechnology)上。一氧化氮是活细胞中最重要的信号分子,具有在大脑内运送信息及调整免疫系统的功能。在许多癌细胞中,一氧化氮水平是波动的,但很少有人知道它在健康细胞和癌细胞内的作用方式。
Massachusetts Institute of Technology researchers recently developed a carbon nanotube sensor, it is implanted under the skin, real-time monitoring of living animals throughout the year of molecular activity, such as inflammation in the process of nitric oxide (NO) , Or monitor blood glucose and insulin levels without having to take a blood test like the traditional way. The research results are published in Nature nanotechnology. Nitric oxide is the most important signal molecule in living cells and has the function of transporting information in the brain and regulating the immune system. Nitric oxide levels fluctuate in many cancers, but few know how it works in healthy and cancerous cells.
