Spectroscopic analysis of biomolecules is vital in diagnostics and pathogen detection, yet the nanoscale dimensions of chiral molecules make light–matter coupling extremely weak. Here, we present an all-dielectric achiral metasurface of air-microcavity cubes that generates strongly superchiral near fields for highly se...

Circular RNAs (circRNAs) have recently emerged as promising biomarkers for the early diagnosis of cancer and the development of targeted therapeutic strategies. However, their detection remains challenging due to their low abundance and the difficulty in discriminating them from their linear RNA counterparts. Herein, a...

The continuous monitoring of food freshness is an effective strategy for mitigating public health concerns stemming from food spoilage. However, conventional testing methodologies necessitate the disruption of the packaging and the preliminary processing of the food item, thereby rendering them primarily applicable t...

Routine monitoring of urinary biomarkers is critical for the early diagnosis of chronic kidney disease (CKD), yet conventional surface-enhanced Raman scattering (SERS) methods often require tedious washing steps to remove unbound reporters. Herein, we report a wash-free, multiplexed SERS chip designed for the spatially...
