| 1 | Nanoplasmonic mid-infrared biosensor for in vitro protein secondary structure detection显示文摘Plasmonic nanoantennas offer new applications in mid-infrared(mid-IR)absorption spectroscopy with ultrasensitive detection of structural signatures of biomolecules,such as proteins,due to their strong resonant near-fields.The amide I fingerprint of a protein contains conformational information that is greatly important for understanding its function in health and disease.Here,we introduce a non-invasive,label-free mid-IR nanoantenna-array sensor for secondary structure identification of nanometer-thin protein layers in aqueous solution by resolving the content of plasmonically enhanced amide I signatures.We successfully detect random coil to crossβ-sheet conformational changes associated withα-synuclein protein aggregation,a detrimental process in many neurodegenerative disorders.Notably,our experimental results demonstrate high conformational sensitivity by differentiating subtle secondary-structural variations in a nativeβ-sheet protein monolayer from those of crossβ-sheets,which are characteristic of pathological aggregates.Our nanoplasmonic biosensor is a highly promising and versatile tool for in vitro structural analysis of thin protein layers. | Dordaneh Etezadi John B Warner IV Francesco S Ruggeri Giovanni Dietler Hilal A Lashuel Hatice Altug | 2017 | Light(Science & Applications)2017，6，1： | 2 |

| 3 | Electrical Excitation of Long-Range Surface Plasmons in PC/OLED Structure with Two Metal Nanolayers显示文摘A current-driven source of long-range surface plasmons(LRSPs)on a duplex metal nanolayer is reported.Electrical excitation of LRSPs was experimentally observed in a planar structure,where an organic light-emitting film was sandwiched between two metal nanolayers that served as electrodes.To achieve the LRSP propagation in these metal nanolayers at the interface with air,the light-emitting structure was bordered by a one-dimensional photonic crystal(PC)on the other side.The dispersion of the light emitted by such a hybrid PC/organic-light-emitting-diode structure(PC/OLED)comprising two thin metal electrodes was obtained,with a clearly identified LRSP resonance peak. | Valery Konopsky Valery Prokhorov Dmitry Lypenko Artem Dmitriev Elena Alieva Giovanni Dietler Sergey Sekatskii | 2020 | Nano-Micro Letters2020，12，3： | 1 |
| 4 | 基于铕掺杂的CsPbI2Br的高效稳定无机钙钛矿太阳能电池显示文摘文章简介根据2018年的认证,有机无机杂化钙钛矿太阳能电池的最新光电转换效率已达23.3%,成为可与硅电池媲美的新型太阳能电池。但钙钛矿中有机组分对热不稳定,虽然全无机钙钛矿(CsPbX3)可以从根本上解决该问题,但是低带隙全无机钙钛矿材料在室温下会从立方相(钙钛矿相)变成正交相(非钙钛矿相),从而失去光学活性。这种相不稳定性成为制约无机钙钛矿太阳能电池发展的瓶颈。 | 向万春 Zaiwei Wang Dominik JKubicki Wolfgang Tress Jingshan Luo Daniel Prochowicz Seckin Akin Lyndon Emsley Jiangtao Zhou Giovanni Dietler Michael Grätzel Anders Hagfeldt | 2020 | 科学新闻2020，，2： | 0 |
