Recent advancements of plasmonic sensor technologies in healthcare and electronics

Abstract

Advancements in materials science and nanotechnology have propelled plasmonic sensors to the forefront of medical and electronics industries. Recent developments in plasmonic sensors, such as the integration of metamaterials and graphene, have significantly enhanced their sensitivity, specificity, and functionality, enabling precise detection of biomarkers and environmental contaminants. Nonetheless, plasmonic sensors face certain challenges, such as sensitivity and specificity problems, complicated and expensive fabrication processes, and the requirement for advanced real-time data analysis and system integration. In the coming years, continued research into sensor miniaturization, multiplexing capacity, and economical manufacturing techniques will help to overcome these issues. From these advances, the potential implications are enormous, giving way to better medical diagnostics, personalized medicine, and electronic applications such as optical communication and data storage. The evolving plasmonic sensor technology is poised to have a transformative impact across the medical and electronics industries, catalyzing advancements in health monitoring, environmental detection, and electronic device capabilities. © 2025 Elsevier B.V.
