In 2004, scientists in University of Manchester first stripped out a single layer of graphene with a thickness of only 0.35 nm. Graphene monolayer is a two-dimensional structure composed of hexagonal carbon rings. It is the thinnest, the strongest and the most conductive of the existing nano materials, known as the "black gold", "the king of new materials", and so on. Therefore, it has become a research hotspot in the field of materials science. Due to its unique physical and chemical properties, graphene has great application prospects in new energy, desalination, hydrogen storage, biomedicine, aerospace, sensors, national defense and military fields. In this paper, the application of graphene in national defense is reviewed. It is believed that with the acceleration of a new round of scientific and technological revolution and military revolution in the world, graphene materials will be the first to open a breakthrough in the field of national defense and achieve greater development.
The 2D MoS2-FET biosensor has the advantages of small size, low power consumption, ultra-fast response, ultra-low detection limit, high sensitivity, and well-integrated circuit compatibility. For now, many 2D MoS2-FET biosensors have been developed for the detection of various types of analytes. In this paper, the research progress of 2D MoS2-FET biosensors in recent years is reviewed, and the prospects and trends in this field are given in combination with the current challenges.
