Abstract
Reliable monitoring of water systems is crucial for human and ecological health. The lead time between sampling and analysis delays responses to naturally occurring events (i.e. changes in salinity, metabolic activity, etc.) and manmade contamination events. Here, we employ plasmonic metasurfaces as 'nano-tastebud' sensors for monitoring the composition of and changes in various water sources. This system, optimized through chemometric analysis, can offer real-time data enhancing response times, helping guide policy, and optimizing water treatment to reduce energy use and carbon footprint.
