Recent Advances in Two-Dimensional Materials based Sensing Technology towards Health and Environmental Applications
Monitoring the harmful and toxic chemicals, gases, micro-organisms and radiation has been the challenge for scientific society for the betterment of human health and environment. Two-dimensional (2D) material based sensors are highly efficient and compatible with modern fabrication technology, which produces data that can be proficiently used for health and environment monitoring. Graphene and its oxides, black phosphorus (BP), transition metal chalcogenides (TMDCs), metal oxides and other 2D nanomaterials have demonstrated prosperities to be alluring for the manufacture of highly sensitive sensor due to their unique material properties which arises from their inherentstructure. This review summarizes the properties of 2D nanomaterials which can provide a platform to develop high performance sensors. In this review, we have also discussed the advances made in the field of infrared photodetectors and electrochemical sensors and how structural properties of 2D nanomaterials affect their sensitivity and performance. This review also highlights the 2D nanomaterial-based electrochemical sensors to check the contaminations like heavy metals, organic/inorganic compounds, poisonous gases, pesticides, bacteria, antibiotics,etc., in water or air, which are severe risk to human well being and environment. Moreover, the limitations, future prospects and challenges for the development of sensors based on 2D materials are also discussed for the future advancements.
