Nanocavity-Based “Turn-Off” Plasmonic Metasurface Sensing Platform for the Detection of Trace Cadmium Ions in Complex Matrices
= 0.999, and an ultra-low detection limit of 3.55 fg/L. This strategy allows extension to other heavy metal ions or biomolecules via tailored aptamer and metasurface design.
