Special Issue Information

Dear Colleagues,

Plasmonic sensors are at the forefront of sensing technology, with recent advancements bringing new levels of sensitivity, selectivity, and multifunctionality to their various applications. Emerging trends are highlighting innovative nanostructured materials, such as novel plasmonic nanomaterials and hybrid nanostructures, which have the potential to transform these sensors’ detection capabilities in chemical, biological, and environmental sensing. These developments, alongside the integration of plasmonic systems with photonic, electronic, and digital technologies, enable highly precise, real-time monitoring in diverse sectors, including in environmental monitoring, medical diagnostics, and security. Notably, the integration of AI and machine learning into plasmonic sensors is amplifying their potential, allowing for enhanced data analysis, pattern recognition, and predictive capabilities that are reshaping sensor accuracy and speed. This Special Issue invites authors to submit original research articles that explore these innovations or review papers that provide comprehensive overviews of the latest advances and trends in plasmonic sensing. We welcome submissions that offer fresh perspectives on new sensing applications and novel material approaches or interdisciplinary insights that will help define the next generation of plasmonic sensor technologies.

Wearable sensors have appeared as a promising solution for real-time, non-invasive monitoring in diverse fields, including healthcare, environmental sensing, and wearable electronics. Surface-enhanced Raman spectroscopy (SERS)-based sensors leverage the unique properties of SERS, such as plasmonic signal enhancement, high molecular specificity, and the potential for single-molecule detection, to detect and identify a wide range of analytes with ultra-high sensitivity and molecular selectivity. However, it is important to note that wearable sensors utilize various sensing mechanisms, and not all rely on SERS technology, as their design depends on the specific application. This comprehensive review highlights the recent trends and advancements in wearable plasmonic sensing technologies, focusing on their design, fabrication, and integration into practical wearable devices. Key innovations in material selection, such as the use of nanomaterials and flexible substrates, have significantly enhanced sensor performance and wearability. Moreover, we discuss challenges such as miniaturization, power consumption, and long-term stability, along with potential solutions to address these issues. Finally, the outlook for wearable plasmonic sensing technologies is presented, emphasizing the need for interdisciplinary research to drive the next generation of smart wearables capable of real-time health diagnostics, environmental monitoring, and beyond.
