2.1. Single Crystalline NanoparticlesThe SERS sensitivity of plasmonic nanoparticles is affected by their size and morphology. The plasmas in the earliest SERS sensors are spherical or quasi-spherical. Now, plasmonic nanoparticles that study surface anisotropy have better SERS sensitivity. More attention has been paid to nanorods, nanospines, nanopores, and other nanostructures that can generate higher hot spots [30].

An Innovative Electrohydrodynamic-Driven SERS Platform for Molecular Stratification and Treatment Monitoring of Lung Cancer The advancement of molecular diagnostics for lung cancer stratification and monitoring is essential for the strategic planning and prompt modification of treatments, aiming to enhance clinical results. To address this need, we suggest a nanocavity structure designed to sensitively analyze the protein signature on small extracellular vesicles (sEVs).

We propose what we believe to be a novel nonlinear optical limiting (NOL) method with a low limiting threshold based on a light intensity-controlled polarizability inversion suspension (PIS). This suspension has negative polarizability under weak light, allowing stable propagation of weak light with a low loss.
