Abstract

Highly Sensitive Raman Sensing In article 2300291, Shieh and co-workers utilize the sticky properties of superhydrophobic nanograss, to immobilize a water droplet containing silver nanoparticles on a surface. When this droplet evaporates, it leaves a small coffee-ring-like stain rich in hot spots. When trace molecules aggregate along the ring edge, they can be repeatedly detected by surface-enhanced Raman scattering. This method provides a reliable and extremely sensitive platform for molecular detection.
