Abstract
AbstractThe advancements in the capabilities of artificial sensory technologies, such as electronic/optical noses and tongues, have significantly enhanced their ability to identify complex mixtures of analytes. These improvements are rooted in the evolving manufacturing processes of cross‐reactive sensor arrays (CRSAs) and the development of innovative computational methods. The potential applications in early diagnosis, food quality control, environmental monitoring, and more, position CRSAs as an exciting area of research for scientists from diverse backgrounds. Among these, plasmonic CRSAs are particularly noteworthy because they offer enhanced capabilities for remote, fast, and even real‐time monitoring, in addition to better portability of instrumentation. Specifically, the synergy between the localized surface plasmon resonance (LSPR) of metallic nanoparticles (NPs) and CRSAs introduces advanced techniques such as LSPR, metal‐enhanced fluorescence (MEF), surface‐enhanced infrared absorption (SEIRA), surface‐enhanced Raman scattering (SERS), and surface‐enhanced resonance Raman scattering (SERRS) spectroscopies. This review delves into the importance and versatility of optical‐CRSAs, especially those based on plasmonic materials, discussing recent applications and potential new research directions.
