Spectroscopy Probe(光谱探头)研究综述
Spectroscopy Probe 光谱探头 - Chiral vibrational sum frequency generation (SFG) spectroscopy probes the structure of the solvation shell around chiral macromolecules. [1] Photoconductive atomic force microscopy (PC-AFM), Kelvin probe force microscopy (KPFM), and photoluminescence (PL) spectroscopy probed the organic/inorganic heterojunctions. [2] The electron beam in TEM is usually used as an imaging or spectroscopy probe for chemical and physical characterization of materials and nanostructures. [3] In this sense, the use of benzothiazole compounds that are highly selective and can act as spectroscopy probes, especially the compound 2-(4′-aminophenyl)benzothiazole (ABT), has been highlighted. [4] Summary Site-directed spin labeling (SDSL) in combination with electron paramagnetic resonance (EPR) spectroscopy probes the otherwise inaccessible structural information in complex biological systems. [5] Here we developed a technique based on UV-vis absorbance spectroscopy, where cysteine was used as a spectroscopy probe to distinguish between heme-bound to plasma proteins or hemoglobin from free heme. [6] Here, the depth settings are obtained by varying the voltage at a second inject on the electrical-impedance-spectroscopy probe. [7] In mammalian cell culture, Radio-Frequency Impedance (RFI) spectroscopy probes are widely used for cell concentration monitoring. [8] In particular, methods that monitor the viability, metabolic activity or related parameters are discussed, like electrochemical, impedance and spectroscopy probes, and methods related to fluid flow and gradient formation, like acoustic and mobile sensors. [9] Widely employed Near-Edge X-Ray Absorption Fine Structure (NEXAFS) spectroscopy probes a system by excitation of core electrons to unoccupied states. [10] Transient extreme ultraviolet (XUV) spectroscopy probes core level transitions to unoccupied valence and conduction band states. [11]手性振动和频产生 (SFG) 光谱探测手性大分子周围的溶剂化壳的结构。 [1] 光电导原子力显微镜 (PC-AFM)、开尔文探针力显微镜 (KPFM) 和光致发光 (PL) 光谱探测了有机/无机异质结。 [2] TEM 中的电子束通常用作成像或光谱探针，用于材料和纳米结构的化学和物理表征。 [3] 从这个意义上说，使用具有高选择性并可作为光谱探针的苯并噻唑化合物，特别是化合物 2-(4'-氨基苯基)苯并噻唑 (ABT) 已被强调。 [4] 总结 定点自旋标记 (SDSL) 与电子顺磁共振 (EPR) 光谱相结合，探测了复杂生物系统中原本无法获取的结构信息。 [5] 在这里，我们开发了一种基于紫外-可见吸收光谱的技术，其中半胱氨酸被用作光谱探针，以区分与血浆蛋白结合的血红素或游离血红素中的血红蛋白。 [6] 在这里，深度设置是通过改变电阻抗光谱探头上第二次注入的电压来获得的。 [7] 在哺乳动物细胞培养中，射频阻抗 (RFI) 光谱探针广泛用于细胞浓度监测。 [8] 特别是，讨论了监测活力、代谢活动或相关参数的方法，如电化学、阻抗和光谱探针，以及与流体流动和梯度形成相关的方法，如声学和移动传感器。 [9] 广泛采用的近边缘 X 射线吸收精细结构 (NEXAFS) 光谱通过将核心电子激发到未占据状态来探测系统。 [10] 瞬态极紫外 (XUV) 光谱探测核心能级跃迁到未占据的价带和导带状态。 [11]
Raman Spectroscopy Probe
Raman spectroscopy probes the biochemical composition of samples in a non-destructive, non-invasive and label-free fashion yielding specific information on a molecular level. [1] The device incorporates a Raman spectroscopy probe for biochemical monitoring and a camera for visualizing measurement location to ensure it is void of cervical mucus and blood. [2] Raman spectroscopy probes the chemical composition of biological samples with sub-micron resolution, rendering it a powerful tool in the diagnosis of several diseases and the study unstained biological samples. [3] Raman spectroscopy probes the unique molecular vibrations of a sample to accurately characterize its molecular composition. [4] By using Raman polarization analyzer, the precise directional information about the differential polarizability of the molecules can be obtained, so polarized Raman spectroscopy probes provide insightful information such as molecular orientation and symmetries of the bond vibrations. [5]拉曼光谱以非破坏性、非侵入性和无标记的方式探测样品的生化成分，从而产生分子水平的特定信息。 [1] 该设备包含一个用于生化监测的拉曼光谱探头和一个用于可视化测量位置的摄像头，以确保没有宫颈粘液和血液。 [2] 拉曼光谱以亚微米分辨率探测生物样品的化学成分，使其成为诊断多种疾病和研究未染色生物样品的有力工具。 [3] 拉曼光谱探测样品的独特分子振动，以准确表征其分子组成。 [4] 通过使用拉曼偏振分析仪，可以获得有关分子差分极化率的精确方向信息，因此偏振拉曼光谱探针提供了诸如分子取向和键振动对称性等深刻的信息。 [5]
Infrared Spectroscopy Probe 红外光谱探头
The near-infrared spectroscopy probe was positioned on the right side of forehead in each infant. [1] The catalytic potential of the samples was investigated in carbon monoxide oxidation reactions at atmospheric pressure, supported by an in situ diffuse reflectance infrared spectroscopy probe. [2] A pulse oximeter and a near-infrared spectroscopy probe were connected to babies during the study period, and the responses of the babies were recorded by video, from which the crying time and the Neonatal Infant Pain Scale were obtained. [3]近红外光谱探头位于每个婴儿前额的右侧。 [1] 在原位漫反射红外光谱探针的支持下，在大气压下的一氧化碳氧化反应中研究了样品的催化潜力。 [2] 在研究期间将脉搏血氧仪和近红外光谱探头连接到婴儿身上，并通过视频记录婴儿的反应，从中获得哭闹时间和新生儿疼痛量表。 [3]
Photoluminescence Spectroscopy Probe
Using a modular microfluidic platform equipped with a translational in situ absorption and photoluminescence spectroscopy probe, we propose a heterogeneous surface-doping mechanism through a vacancy-assisted metal cation migration. [1] Photoluminescence spectroscopy probe has revealed large amount of defects in Sn doped NiO nanostructures. [2]使用配备平移原位吸收和光致发光光谱探针的模块化微流体平台，我们通过空位辅助金属阳离子迁移提出了异质表面掺杂机制。 [1] 光致发光光谱探针揭示了Sn掺杂的NiO纳米结构中的大量缺陷。 [2]
