By varying a metasurface’s geometry continuously across a chip, a recent study by H. Kim et al. reports a new sensing strategy, which reads signals from individual camera images without the need for a spectrometer. This enables the label-free detection of biomarkers in a handheld format.en2041-172320261Nature Publishing Grouphttps://creativecommons.org/licenses/by/4.0/Technology::660: Chemistry; Chemical Engineering::660.6: BiotechnologyTechnology::610: Medicine, HealthJournal Article2026-10-1510.1038/s41467-026-78586-710.15480/882.18898
