A review of gap-surface plasmon metasurfaces: fundamentals and applications
Nanophotonics - Tập 7 Số 6 - Trang 1129-1156 - 2018
Fei Ding, Yuanqing Yang, R. Deshpande, Sergey I. Bozhevolnyi
AbstractPlasmonic metasurfaces, which can be considered as the two-dimensional analog of metal-based metamaterials, have attracted progressively increasing attention in recent years because of the ease of fabrication and unprecedented control over the reflected or transmitted light while featuring relatively low losses even at optical wavelengths. Among all the different design approaches, gap-sur... hiện toàn bộ
Photodynamic priming with triple-receptor targeted nanoconjugates that trigger T cell-mediated immune responses in a 3D in vitro heterocellular model of pancreatic cancer
Nanophotonics - Tập 10 Số 12 - Trang 3199-3214 - 2021
Pushpamali De Silva, Shazia Bano, Brian W. Pogue, Kenneth K. Wang, Edward V. Maytin, Tayyaba Hasan
Abstract Photodynamic priming (PDP), a collateral effect of photodynamic therapy, can transiently alter the tumor microenvironment (TME) beyond the cytotoxic zone. Studies have demonstrated that PDP increases tumor permeability and modulates immune-stimulatory effects by inducing immunogenic cell death, via the release of damage-associated molecular patterns and tumor-associated antigens.

Facile fabrication of stretchable photonic Ag nanostructures by soft-contact patterning of ionic Ag solution coatings
Nanophotonics - Tập 11 Số 11 - Trang 2693-2700 - 2022
Minwook Kim, Dong Kyo Oh, Jeong Dae Kim, Minsu Jeong, Hongyoon Kim, Chunghwan Jung, Jungkeun Song, Won‐Jun Lee, Junsuk Rho, Jong G. Ok
Abstract We describe a rapid and simple method to create Ag nanostructures by using direct mechanical patterning of ionic Ag ink coating under gentle pressure, then thermal annealing to reduce the ionic Ag ink to a metallic Ag layer. The ionic liquid-phase Ag coating is easily obtained by spin-coating ionic Ag ink that has appropriate Ag concentration and can be either printed or imprinted on the ... hiện toàn bộ
Indium-Tin-Oxide for High-performance Electro-optic Modulation
Nanophotonics - Tập 4 Số 1 - Trang 198-213 - 2015
Zhizhen Ma, Zhuoran Li, Ke Liu, Chenran Ye, Volker J. Sorger
Abstract:Advances in opto-electronics are often led by discovery and development of materials featuring unique properties. Recently, the material class of transparent conductive oxides (TCO) has attracted attention for active photonic devices on-chip. In particular, indium tin oxide (ITO) is found to have refractive index changes on the order of unity. This property makes it possible to achieve el... hiện toàn bộ
Observing and controlling a Tamm plasmon at the interface with a metasurface
Nanophotonics - Tập 9 Số 4 - Trang 897-903 - 2020
Oleksandr Buchnev, Alexandr Belosludtsev, Victor Reshetnyak, D. R. Evans, V.A. Fedotov
Abstract We demonstrate experimentally that Tamm plasmons in the near infrared can be supported by a dielectric mirror interfaced with a metasurface, a discontinuous thin metal film periodically patterned on the sub-wavelength scale. More crucially, not only do Tamm plasmons survive the nanopatterning of the metal film but they also become sensitive to external perturbations as a result. In partic... hiện toàn bộ
Graphene plasmonics: physics and potential applications
Nanophotonics - Tập 6 Số 6 - Trang 1191-1204 - 2016
Shenyang Huang, Chaoyu Song, Guowei Zhang, Hugen Yan
AbstractPlasmon in graphene possesses many unique properties. It originates from the collective motion of massless Dirac fermions, and the carrier density dependence is distinctively different from conventional plasmons. In addition, graphene plasmon is highly tunable and shows strong energy confinement capability. Most intriguingly, as an atom-thin layer, graphene and its plasmon are very sensiti... hiện toàn bộ
A review of 2D and 3D plasmonic nanostructure array patterns: fabrication, light management and sensing applications

Abstract This review article discusses progress in surface plasmon resonance (SPR) of two-dimensional (2D) and three-dimensional (3D) chip-based nanostructure array patterns. Recent advancements in fabrication techniques for nano-arrays have endowed researchers with tools to explore a material’s plasmonic optical properties. In this review, fabrication techniques including electron-beam lithograph... hiện toàn bộ
Stretchable and self-healable organometal halide perovskite nanocrystal-embedded polymer gels with enhanced luminescence stability
Nanophotonics - Tập 7 Số 12 - Trang 1949-1958 - 2018
Minjie Fang, Sihui Huang, Dong Li, Chunli Jiang, Pei Tian, Hechun Lin, Chunhua Luo, Wenlei Yu, Hui Peng
Abstract Stretchable and self-healing polymer gels with luminescent property are very promising materials for next generation soft optical devices. This work presents the preparation of self-healing and luminescent polymer gels by simply blending organometal halide perovskite nanocrystals (OHP NCs) with poly(dimethylsiloxane)-urea copolymer (PDMS-urea). On the one hand, the obtained luminescent ge... hiện toàn bộ
Optical, photonic and optoelectronic properties of graphene, h-BN and their hybrid materials
Nanophotonics - Tập 6 Số 5 - Trang 943-976 - 2017
Jingang Wang, Fengcai Ma, Wenjie Liang, Rongming Wang, Mengtao Sun
Abstract Because of the linear dispersion relation and the unique structure of graphene’s Dirac electrons, which can be tuned the ultra-wide band, this enables more applications in photonics, electronics and plasma optics. As a substrate, hexagonal boron nitride (h-BN) has an atomic level flat surface without dangling bonds, a weak doping effect and a response in the far ultraviolet area. So the g... hiện toàn bộ
All-optical modulation based on MoS2-Plasmonic nanoslit hybrid structures
Nanophotonics - Tập 10 Số 16 - Trang 3957-3965 - 2021
Feiying Sun, Changbin Nie, Xingzhan Wei, Mao Hu, Yupeng Zhang, Guo Ping Wang
Abstract Two-dimensional (2D) materials with excellent optical properties and complementary metal-oxide-semiconductor (CMOS) compatibility have promising application prospects for developing highly efficient, small-scale all-optical modulators. However, due to the weak nonlinear light-material interaction, high power density and large contact area are usually required, resulting in low light modul... hiện toàn bộ
