2D materials and van der Waals heterostructures platforms for advanced sensing of COVID-19 Chapter uri icon


  • Effective, low-cost, reliable, and versatile diagnosing of SARS-CoV-2 is a critical factor for containing the pandemic outbreak of COVID-19. 2D materials (2DMs) have recently emerged as very promising platforms for biomedical sensors since they offer high surface area and a wide range of tunable electronic, mechanical, and optical properties. In addition, 2DMs surfaces allow adjusting the interfacial phenomena, substantial property for the tailored design of the sensing mechanism, and successful device fabrication. In this chapter, achievements in the detection of COVID-19 using platforms produced from graphene, 2DMs, and their van der Waals (vdW) heterostructures are summarized. The most important outcomes of the use of 2DMs in COVID-19 detection such as cost-effective, massive production, the possibility for device manufacture, the fabrication of point-of-care test kids, and their straightforward capacity to interconnect to the Internet of Things are characteristics expected to produce devices able to sense, record, monitor, and respond. These abilities, in synergy, might help to minimize the spread of COVID-19 and further pandemic outbreaks. © 2022 Elsevier Inc. All rights reserved.
