Layered transition-metal dichalcogenides (MoS2 and WS2) for sensing and biosensing

• Layered transition-metal dichalcogenides for analytical chemistry.
• New materials in sensing using layered transition-metal dichalcogenides.
• New materials in biosensing using layered transition-metal dichalcogenides.
• Electrochemical and fluorescence detection schemes using MoS2 and WS2.

Layered transition-metal dichalcogenides comprise a category of two-dimensional materials that offer exciting properties, including metallic and semi-conducting electrical capabilities, fluorescence and fast heterogeneous electron transfer. To date, these materials have mostly been employed in energy-storage and generation devices. However, in very recent times, there was a significant emerging trend in their utilization in analytical chemistry. Hence, this review aims to provide an introduction to this new trend for the analytical community.
