TaS₂ nanosheet-based humidity sensors show ultrafast response for multifunctional applications, benefiting from a high surface/volume ratio.

V₂O₅ nanotube arrays were grown on V₂C nanosheets to suppress the shuttle effect and extend the life of lithium–sulfur batteries.

MXenes-based van der Waals heterojunction materials with excellent chemical stability and bioaffinity have been widely used in biosensing in recent years. We propose a new MoSe ₂ @Zr ₂ CO ₂ heterostructure as a long-range surface plasmon resonance (LRSPR) sensor based on the Kretschmann configuration from simulation and optimize the structure parameters algorithmically. Firstly, we investigate the effect of different layers of MoSe ₂ @Zr ₂ CO ₂ heterojunction on the LRSPR wave. The results show that the optimal number of layers for heterogeneous layers is 18. Secondly, the effects of dielectric thickness and refractive index on sensitivity are investigated in depth, and optimized structural parameters are obtained. Finally, the effect of prisms with different refractive coefficients on the sensor performance is also discussed, and it is shown that prisms with lower refractive coefficients can effectively improve the sensitivity performance of the sensor. The sensor response performance to biomolecules is greatly enhanced due to the gain of light absorption and surface plasmon resonance. Compared with the conventional precious metal Au-based (50 nm) thin-film SPR sensor, the figure of merit (FOM) of the sensor is improved by a factor of 8.16, and higher sensitivity (92.48°/RIU) and quality factor (319.63 RIU ^-1 ) are obtained in the visible range.
