The functional properties of organic-inorganic (O-I) hybrids can be easily tuned by combining system components and parameters, making this class of novel nanomaterials a crucial element in various application fields. Unfortunately, the manufacturing of organic-inorganic nanohybrids still suffers from mechanical instability and insufficient synthesis reproducibility. The control of the composition and structure of nanosurfaces themselves is a specific analytical challenge and plays an important role in the future reproducibility of hybrid nanomaterials surface properties and response. Therefore, appropriate and sufficient analytical methodologies and technical guidance for control of their synthesis, characterization and standardization of the final product quality at the nanoscale level should be established. In this review, we summarize and compare the analytical merit of the modern analytical methods, viz. Fourier transform infrared spectroscopy (FTIR), RAMAN spectroscopy, surface plasmon resonance (SPR) and several mass spectrometry (MS)-based techniques, that is, inductively coupled plasma mass spectrometry (ICP-MS), single particle ICP-MS (sp-ICP-MS), laser ablation coupled ICP-MS (LA-ICP-MS), time-of-flight secondary ion mass spectrometry (TOF-SIMS), liquid chromatography mass spectrometry (LC-MS) utilized for characterization of O-I nanohybrids. Special attention is given to laser desorption ionization mass spectrometry (LDI-MS) as a reliable nanoanalytical platform for characterization of O-I hybrid nanomaterials, their quality, design verification and validation.
通过组合系统组件和参数,可以轻松调整有机-无机(O-I)杂化材料的功能特性,使这类新型纳米材料成为各个应用领域的关键元素。不幸的是,有机-无机纳米杂化材料的制造仍然存在机械稳定性不足和合成重现性不够的问题。控制纳米表面本身的组成和结构是一项特殊的分析挑战,并且在杂化纳米材料表面性质和响应的未来重现性方面起着重要作用。因此,应该建立适当且充分的分析方法和技术指导,以在纳米尺度上控制其合成、表征以及最终产品质量的标准化。在本综述中,我们总结并比较了现代分析方法的分析优点,即傅里叶变换红外光谱(FTIR)、拉曼光谱、表面等离子体共振(SPR)以及几种基于质谱(MS)的技术,也就是电感耦合等离子体质谱(ICP-MS)、单颗粒ICP-MS(sp-ICP-MS)、激光烧蚀耦合ICP-MS(LA-ICP-MS)、飞行时间二次离子质谱(TOF-SIMS)、用于表征O-I纳米杂化材料的液相色谱质谱(LC-MS)。特别关注激光解吸电离质谱(LDI-MS)作为一种可靠的纳米分析平台,用于表征O-I杂化纳米材料、它们的质量、设计验证和确认。
