Functional Electroactive 2D-Materials for Bio and Chemical Sensing

在过去的十年里，包括石墨烯在内的电活性二维(2D)材料家族经历了爆炸性的增长。人们对合理设计2D材料纳米结构的可能性产生了浓厚的兴趣，这种结构最终可能导致新型传感器能够在分子水平上检测分析物，无论是在生物系统还是在化学系统中。在拟议的计划中，将解决以下关键挑战：(I)下一代电活性2D材料家族的增长，包括石墨烯、氮化硼和过渡金属二卤化物(例如MoS2和WSe2)。(2)元素周期表(P、As、Sb、Bi)V基团的剥离和随后的表征。3)二维材料功能化和器件制造，设计高性能的环境监测传感器。这个雄心勃勃的目标定义了一个特殊的机会，可以加入到绘制2D材料家族和绘制它们的属性的国际努力中，这一努力现在才开始进行。

In the last decade, electroactive two-dimensional (2D) materials family including graphene have seen an explosive growth. Intense interest is generated by the possibility of rationally designing 2D material nanostructures that may ultimately lead to novel sensors able to detect analyte at the molecular level, be it in biological or chemical systems. In the proposed program the following key challenges will be addressed: (i) the growth of next generation of electroactive 2D materials family including graphene, boron nitride and transition metal dichalgonides (e.g. MoS2 and WSe2). (ii) Exfoliation and subsequent characterization of the V group of the periodic table (P, As, Sb, Bi). iii) 2D material functionalization and devices fabrication to design high-performance sensors for environmental monitoring. This ambitious goal defines a special opportunity to join the international effort to map out the 2D-material family and to chart their properties that is only now underway.
