“…Photothermal (PTT) antibacterial hydrogels were an effective strategy to treat bacterial infections using hyperthermia generated by photothermal materials under visible or near-infrared light irradiation [ 15 , 17 ]. These hydrogels could convert light into heat mainly by relying on noble metal materials [ 18 ], 2D nanomaterials such as black phosphorus (BP) nanosheets [ 19 ], and transition metal sulfides (molybdenum disulfide (MoS 2 )) [ 20 ] et al…”

Wounds, particularly under low-hydration conditions, require more time to repair successfully. Therefore, there is an urgent need to develop wound dressings that can accelerate wound healing. Hydrogels, which can maintain a moist environment around the wound and allow gas to pass through the material, act as antibacterial hydrogels as dressings and have great application value in the treatment of wounds. In addition, wound dressings (hydrogels) containing antibacterial capacity have lasting antibacterial effects and reduce damage to cells. In this work, we firstly synthesized two antibacterial agents: imidazolium poly(ionic liquids) containing sulfhydryl (Imidazole-SH) and ε-Poly(lysine) containing SH (EPL-SH). Then, lysine as a cross-linking agent, by “thiol-ene” click reaction, was mixed with Deferoxamine (DFO) to prepare the antibacterial hydrogels. The in vitro assays showed that the hydrogels could effectively kill Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). In addition, it also could reduce the inflammatory response produced by Lipopolysaccharide (LPS). More importantly, according to the transwell and angiogenesis assays, DFO-incorporated hydrogels promoted the migration and vascular repair of human umbilical vein endothelial cells (HUVECs). All the results revealed that the hydrogels provided new strategies for wound dressings.

“…In comparison, multilayer structures can be created by alternate stacking of BP and SiO 2 . 934 The inplane anisotropy of the BP material can be used to introduce anisotropic photonic topological transition effects. The effective medium theory (eqs 10, 11, 14, and 15) can also be used to calculate the effective permittivity of the metamaterial along the three orthogonal directions by using the different refractive indices along armchair and zigzag directions.…”

“…Song et al theoretically studied a multilayer hyperbolic metamaterial structure composed of few-layer BP and gold thin films (Figure e–g), for which the effective permittivity along the x and y directions are positive and negative, respectively. In comparison, multilayer structures can be created by alternate stacking of BP and SiO 2 . The in-plane anisotropy of the BP material can be used to introduce anisotropic photonic topological transition effects.…”

The outstanding chemical and physical properties of 2D materials, together with their atomically thin nature, make them ideal candidates for metaphotonic device integration and construction, which requires deep subwavelength light–matter interaction to achieve optical functionalities beyond conventional optical phenomena observed in naturally available materials. In addition to their intrinsic properties, the possibility to further manipulate the properties of 2D materials via chemical or physical engineering dramatically enhances their capability, evoking new science on light–matter interaction, leading to leaped performance of existing functional devices and giving birth to new metaphotonic devices that were unattainable previously. Comprehensive understanding of the intrinsic properties of 2D materials, approaches and capabilities for chemical and physical engineering methods, the resulting property modifications and novel functionalities, and applications of metaphotonic devices are provided in this review. Through reviewing the detailed progress in each aspect and the state-of-the-art achievement, insightful analyses of the outstanding challenges and future directions are elucidated in this cross-disciplinary comprehensive review with the aim to provide an overall development picture in the field of 2D material metaphotonics and promote rapid progress in this fast emerging and prosperous field.

“…In particular, the dispersion properties play a critical role in determining the performance of optical metamaterials. The hyperbolic metamaterials (HMMs) are a class of metamaterials whose isofrequency contours exhibit a hyperbolic shape [4][5][6]. In contrast to traditional metamaterials with fixed dispersion relations such as plasma and all-dielectric, HMMs * Author to whom any correspondence should be addressed.…”

We investigate the Goos-Hänchen (GH) shift in a hyperbolic metamaterial (GHMM) comprising graphene and vanadium dioxide (VO2) as the dielectric. Our study reveals that the dispersion type of GHMM can be controlled via Fermi energy of graphene and temperature, modulating wavelength intervals. Notably, the GH shift in type I dispersion surpasses that in elliptical and type II dispersions. This suggests GH shift control by altering dispersion in GHMM. Thickness variations in VO2 and the number of graphene/VO2 layers minimally affect GH shift. In contrast, graphene thickness significantly impacts GH shift, with thicker graphene yielding minor shifts. Meanwhile, we discover that substantial GH shift enhancement by surface plasmon resonance (SPR) excitation, with sensitivity to refractive index changes in the sensing layer. Based on the above conclusions, we theoretically propose a highly tunable biosensor uniting GHMM with SPR and use it to distinguish normal cells from cancer cells. This work advances optical biosensors and precise physical quantity measurements.
