A new light-based sensor could help make ultrasensitive disease testing more portable

Phys · May 21, 2026 · 1207 words · By Liaoyong Wen; Jiacheng Sun

Researchers have developed a new light-based sensor using Q-modulated refractometric sensing to detect biomolecules with high sensitivity. The system utilizes a 3D metasurface to convert small refractive-index changes into electrical signals, demonstrating potential for portable lung cancer screening via extracellular vesicles.
