| 1 | Active control of EIT-like response in a symmetry-broken metasurface with orthogonal electric dipolar resonators显示文摘The active control of electromagnetic response in metamaterial and mutual coupling between resonant building blocks is of fundamental importance in realizing high-quality metamaterials. In this work, we propose and experimentally demonstrate the tunabilities of symmetry-broken metasurfaces made of orthogonal electric dipolar resonators. The metasurface with vertical and horizontal wires is integrated with a PIN diode for active control.It is found that the electromagnetically induced transparency(EIT)-like spectrum appears due to the destructive or constructive interferences between the two electric dipolar modes when the structural symmetry broken is introduced to the metasurface. Different from previous works on the EIT-like effect, there is only electric dipole response in our metasuface. The microscopic response of the metasurface is numerically calculated to illustrate the mode coupling between the orthogonal electric dipolar resonators. By applying temporal coupled-mode theory,the interaction between the electromagnetic wave and the symmetry-broken metasurface is described, and the characteristic parameters of the resonator system, which determine the electromagnetic response of the metasurface, are acquired. | RUISHENG YANG QUANHONG FU YUANCHENG FAN WEIQI CAI KEPENG QIU WEIHONG ZHANG FULI ZHANG | 2019 | Photonics Research2019，7，9： | 3 |
| 2 | A high stable pH-temperature dual-sensitive liposome for tuning anticancer drug release显示文摘In order to improve the targeting and availability of liposomes to cancer cells,the temperature sensitivity of 1,2-Dipalmitoyl-sn-glycero-3-phosphocholine(DPPC)and the pH sensitivity of PASP in PASP-g-C8 are incorporated in a drug delivery system.A composite pH-temperature dual-sensitive liposomes(CPTLPs)was obtained as an efficient drug delivery system.The bionic bilayer is self-assembled by cholesterol/cationic temperature-sensitive lipids as base layer and pH-sensitive octylamine grafted poly aspartic acid(PASP-g-C8)as anchors coated outside.Cytarabine(CYT)was chosen as a model drug.SEM and DLS were used to observe the morphology characteristics of CPTLPs in different micro environment.The results demonstrated that the CPTLPs remained active in both normal(pH7.4 and 37°C)and tumor tissues(pH 5.0 and 42°C).As a stable colloidal system,the zeta potential of CPTSLs was−41.6 mV.In vitro drug-release experiments,the CTY encapsulated dual-sensitive liposomes,CPTSLs(+),not only have significant pH-temperature sensitivity but have more prolonged release in vitro than control groups.MTT tests results indicated that the cell apoptotic effects induced by CPTSLs(+)were nearly 30%higher than the naked drug CTY in HepG2 cells,and 20%lower apoptotic in vero cells.The CPTSLs(+)sustained a stable emulsion form,less toxic effects on normal cells,and exhibited a good pH-temperature sensitivity,thus expected to be a promising tumor targeting drug delivery. | Yilin Zhao Fuli Cai Xiangyi Shen Haijia Su | 2020 | Synthetic and Systems Biotechnology2020，5，2： | 2 |

| 5 | Fano-Resonant Hybrid Metamaterial for Enhanced Nonlinear Tunability and Hysteresis Behavior显示文摘Artificial resonant metamaterial with subwavelength localized filed is promising for advanced nonlinear photonic applications.In this article,we demonstrate enhanced nonlinear frequency-agile response and hysteresis tunability in a Fano-resonant hybrid metamaterial.A ceramic cuboid is electromagnetically coupled with metal cut-wire structure to excite the high-Q Fano-resonant mode in the dielectric/metal hybrid metamaterial.It is found that the significant nonlinear response of the ceramic cuboid can be employed for realization of tunable metamaterials by exciting its magnetic mode,and the trapped mode with an asymmetric Fano-like resonance is beneficial to achieve notable nonlinear modulation on the scattering spectrum.The nonlinear tunability of both the ceramic structure and the ceramic/metal hybrid metamaterial is promising to extend the operation band of metamaterials,providing possibility in practical applications with enhanced light-matter interactions. | Yuancheng Fan Xuan He Fuli Zhang Weiqi Cai Chang Li Quanhong Fu Nataliia V.Sydorchuk Sergey L.Prosvirnin | 2021 | Research2021，，1： | 0 |
