据悉,南开大学物理科学学院田建国、刘智波研究组利用全内反射下石墨烯对介质折射率异常敏感的光学现象,实现了超灵敏单细胞实时流动传感。这一成果可使癌细胞在形成之初即被精确“光测”出来,将为癌症预防提供一条新途径。石墨烯是一种呈蜂巢状排列的单层碳原子结构,是目前已知的最薄、最坚硬的纳米材料。在全内反射这种特殊的结
It is reported that Nankai University Tian Jianguo, Liu Zhibo research group using graphene under total internal reflection of the medium refractive index is extremely sensitive to optical phenomena, to achieve ultra-sensitive single-cell real-time flow sensing. This result allows cancer cells to be accurately “measured” at the beginning of their formation, which will provide a new way for cancer prevention. Graphene is a honeycomb arrangement of single-layer carbon atom structure, is the thinnest, the most hard and now known nano-materials. In total internal reflection this special knot
