New on-chip device uses exotic light rays in 2D material to detect molecules. Researchers have developed a highly sensitive detector for identifying molecules via their infrared vibrational “fingerprint”. Published in Nature Communications, this innovative detector converts incident infrared light into ultra-confined “nanolight” in the form of phonon polaritons within the detector´s active area. This mechanism serves two crucial purposes: it boosts the overall detector´s sensitivity and enhances the vibrational fingerprint of nanometer-thin molecular layer placed on top of the detector, allowing…
Lung cancer remains one of the leading causes of cancer-related mortality, with lung adenocarcinoma (LUAD) and lung squamous cell carcinoma (LUSC) representing the most prevalent subtypes of non-small cell lung cancer (NSCLC).
