Abstract

Vapor-phase molecular detection is an emerging approach in human-associated fields like environmental monitoring, human health, agriculture, and national defense. Recently, trace-level detection of molecules in the vapor phase has been recognized as a promising and extremely challenging approach. In this context, surface-enhanced Raman spectroscopy (SERS) is a potential technique that offers extremely high sensitivity and superior capability of finding molecular fingerprints down to the ppb level. This review critically delineates SERS's expansive progressions and engagement in the vapor-phase detection of explosives, volatile organic compounds (VOC), and gaseous molecules. Furthermore, we concisely describe the research landscape of vapor-phase detection in various fields and propose insights into potential prospects for imminent advancements. Additionally, the review emphasizes the future standpoints on technical and theoretical expansion and addresses the research gap to create a versatile platform for the betterment of society.

基于sers的危险分子气相传感:最新发展和机遇
气相分子检测在环境监测、人体健康、农业和国防等与人类相关的领域是一种新兴的方法。近年来,气相分子的痕量水平检测已被认为是一种有前途且极具挑战性的方法。在这种情况下,表面增强拉曼光谱(SERS)是一种潜在的技术,它提供了极高的灵敏度和卓越的能力,可以找到低至ppb水平的分子指纹。这篇综述批判性地描述了SERS在炸药、挥发性有机化合物(VOC)和气体分子的气相检测中的广泛进展和参与。此外,我们简要地描述了气相检测在各个领域的研究前景,并提出了对即将取得进展的潜在前景的见解。此外,本文还强调了未来在技术和理论扩展方面的立场,并解决了研究差距,为社会的改善创造了一个多功能的平台。
