“…Therefore, scholars have proposed various models to enhance the absorption of infrared wavelengths and modulate the detection spectrum. Bercea et al [4] revealed the localized surface plasmon resonance modulation from near-to mid-infrared (1.5-4.5 μm) through the synthesis and shape modifications of Au quasi-triangular nanoplatelets arrays. Aslan et al [5] designed novel metamaterials absorber using honeycomb plasmonic nanoantennas.…”

Dual-band infrared absorbers have received a great deal of attention for their potential applications in the field of sensing and detection. In this paper, we proposed a composite model consisting of Platinum nano-cylinder and micro-ring column stacked on top of Si3N4 and Platinum films. The effect of geometrical parameters on spectral absorption was explored by FDTD methods, and the results revealed that there were narrow perfect absorption peaks in each of the two atmospheric window bands due to the magnetic polaritons. Meanwhile, the quantitative relationship of resonance wavelength and geometrical parameters were predicted by LC equivalent circuits. In addition, graphene was added to the structure to dynamically adjust the resonance wavelength by varying the Fermi level. The combination of graphene and microstructure achieved full coverage detection of wavelengths in the atmospheric window range. This dual-band absorber has potential applications in infrared detection because of its good absorption properties and its tunability.

“…It is extremely advantageous to develop strategies for synthesizing, controlling, and utilizing plasma structures with uniform nanoscale gaps to achieve the spatial and geometry arrangement between particles. Although some effective and tunable structures have been reported, such as the preparation of nanoarrays based on lithography technology, − the periodic array structure based on infrared optical LSPR modulation, , and the formation of functional plasma nanostructures using hydrogel colloidal monolayers, , they often have some disadvantages including not being easily manipulated with uncontrolled nanoparticle spacing, low sensitivity, and not being produced at a large scale.…”

Plasmonic nanostructures have a desirable surfaceenhanced Raman scattering (SERS) response related to particle spacing. However, precisely controlling the distance of plasmonic nanostructures is still a challenge. DNA has the merit of specific recognition, and flexible modification of functional groups, which can be used to flexibly adjust the gaps between plasmonic nanostructures for improving the stability of SERS. In this paper, DNA-guided gold nanoparticles formed one-dimensional ordered structures and they were self-assembled at the water−oil interface by a bottom-up approach. Notably, an output switching strategy successfully transfers a small amount of target into a large amount of reporter DNA; thereby, Raman probes are captured on the sensing interface and achieve the SERS assay of microRNA 155 . This study is an exciting strategy for obtaining ordered plasmonic structures and providing surveillance, which is important for the clinical diagnosis of early-stage cancer.
