2D Materials towards sensing technology: From fundamentals to applications

Versatile MXenes as electrochemical sensors for heavy metal ions and phenolic moiety-containing industrial chemicals: recent development and prospects

“…A survey of the literature revealed that EC sensors were increasingly built using 2D materials that included graphene-based materials, transition metal dichalcogenides (TMDCs), black phosphorous (BP), hexagonal boron nitride (h-BN), metal-oxides (MO), metalorganic frameworks (MOFs), 2D carbides and nitrides of transition metals (MXenes). 18,24,28,[32][33][34][35][36] Their unique physicochemical properties are to be exploited and employed in fabricating EC sensors for enhanced selectivity and sensitivity. Modern EC sensors utilize various features to determine the physical, chemical, and biological aspects of day-to-day life.…”

2D material-based sensing devices: an update

“…Moreover, the non-covalent features of 2D materials can be studied based on their van der Waals, electrostatic, and π–π interactions, which can be used to change the doping concentrations in a controllable way. 87 Given that conductivity is a characteristic of graphene and other 2D materials that improves sensitivity, particularly in electrically transduced sensors, 38 it is now conceivable to scale miniature devices due to the exceptional charge transport properties of 2D materials, which are preserved in thin sub-nanometer layers. Furthermore, the large lateral dimensions of 2D materials ensure excellent electrical contacts in electronic devices.…”

“…73,90 However, there are some limitations associated with these materials, particularly in the eld of sensing. 87 The zero band gap of graphene is a signicant disadvantage for any optoelectronic application. Similarly, the application and development of MoS 2 is limited by its many shortcomings.…”

Hole‐Mediated RKKY Interaction in 2D Ferromagnetic CrTe2 Ultra‐Thin Films

“…2D magnetic materials possess unique advantages in the field of spintronics and have witnessed significant progress. [1][2][3][4][5] The family of 2D van der Walls (vdW) magnetic materials, [6][7][8] such as CrTe 2 , [9][10][11][12][13] Fe 3 GeTe 2 , [14,15] CrI 3 , [16][17][18] and CrBr 3 , [19,20] etc., typically exhibit excellent magnetic responses and they have been explored for various novel applications. [21,22] Among them, highquality epitaxial thin films of CrTe 2 have been successfully grown on multiple substrates, displaying excellent perpendicular magnetic anisotropy (PMA) at near-room temperatures.…”
