Plasmonic Nanomaterials for Sensing and Detection of Pathogens

Juniper Hollis*

The rapid detection of pathogens is critical for public health, clinical diagnostics, and environmental monitoring. Plasmonic nanomaterials have garnered significant attention as promising candidates for pathogen sensing and detection due to their unique optical properties, including surface plasmon resonance (SPR) and localized surface plasmon resonance (LSPR). These materials exhibit strong interactions with light, which can be harnessed to detect the presence of specific biomolecules, including pathogens, with high sensitivity and specificity. Plasmonic nanomaterials, such as gold and silver nanoparticles, nanorods, and nanoshells, offer advantages like fast response times, label-free detection, and compatibility with portable devices. This article explores the principles of plasmonic sensing, the different types of plasmonic nanomaterials used in pathogen detection, and their applications in diagnosing infectious diseases. Challenges related to the specificity, sensitivity, and real-time monitoring capabilities of plasmonic sensors, as well as future directions for research, are also discussed.
