Spectroscopy Probes(光谱探头)研究综述
Spectroscopy Probes 光谱探头 - Chiral vibrational sum frequency generation (SFG) spectroscopy probes the structure of the solvation shell around chiral macromolecules. [1] 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. [2] Summary Site-directed spin labeling (SDSL) in combination with electron paramagnetic resonance (EPR) spectroscopy probes the otherwise inaccessible structural information in complex biological systems. [3] In mammalian cell culture, Radio-Frequency Impedance (RFI) spectroscopy probes are widely used for cell concentration monitoring. [4] 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. [5] Widely employed Near-Edge X-Ray Absorption Fine Structure (NEXAFS) spectroscopy probes a system by excitation of core electrons to unoccupied states. [6]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] 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。 [2] 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。 [3] 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。 [4] 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。 [5] 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。 [6]
Raman Spectroscopy Probes
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] 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. [2] Raman spectroscopy probes the unique molecular vibrations of a sample to accurately characterize its molecular composition. [3] 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. [4]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] 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。 [2] 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。 [3] 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。 [4]
