Abstract：
The purpose of this paper is to provide an in-depth review of plasmonic metal nanoparticles made from rhodium, platinum, gold, or silver. We describe fundamental concepts, synthesis methods, and optical sensing applications of these nanoparticles. Plasmonic metal nanoparticles have received a lot of interest due to various applications, such as optical sensors, single-molecule detection, single-cell detection, pathogen detection, environmental contaminant monitoring, cancer diagnostics, biomedicine, and food and health safety monitoring. They provide a promising platform for highly sensitive detection of various analytes. Due to strongly localized optical fields in the hot-spot region near metal nanoparticles, they have the potential for plasmon-enhanced optical sensing applications, including metal-enhanced fluorescence (MEF), surface-enhanced Raman scattering (SERS), and biomedical imaging. We explain the plasmonic enhancement through electromagnetic theory and confirm it with finite-difference time-domain numerical simulations. Moreover, we examine how the localized surface plasmon resonance effects of gold and silver nanoparticles have been utilized for the detection and biosensing of various analytes. Specifically, we discuss the syntheses and applications of rhodium and platinum nanoparticles for the UV plasmonics such as UV-MEF and UV-SERS. Finally, we provide an overview of chemical, physical, and green methods for synthesizing these nanoparticles. We hope that this paper will promote further interest in the optical sensing applications of plasmonic metal nanoparticles in the UV and visible ranges.
摘要：
本文的目的是对由铑制成的等离子体金属纳米颗粒进行深入的综述，铂金,黄金,或银色。我们描述了基本概念，合成方法，以及这些纳米粒子的光学传感应用。由于各种应用，等离子体金属纳米粒子受到了很多关注，如光学传感器，单分子检测，单细胞检测，病原体检测，环境污染物监测，癌症诊断，生物医学,以及食品和健康安全监测。它们为各种分析物的高灵敏度检测提供了有前途的平台。由于在金属纳米颗粒附近的热点区域中存在强烈的局部光场，它们具有等离子体激元增强光学传感应用的潜力，包括金属增强荧光（MEF），表面增强拉曼散射(SERS),和生物医学成像。我们通过电磁理论解释了等离子体增强，并用时域有限差分数值模拟证实了这一点。此外，我们研究了金和银纳米粒子的局部表面等离子体共振效应如何被用于各种分析物的检测和生物传感。具体来说,我们讨论了铑和铂纳米粒子在UV等离子体激元如UV-MEF和UV-SERS中的合成和应用。最后,我们提供化学概述，物理，和合成这些纳米粒子的绿色方法。我们希望本文将促进等离子体金属纳米粒子在紫外和可见光范围内的光学传感应用的进一步兴趣。
