Description
Chenglong Guo and co-authors build in a 2025 study a cheaper, faster version of a label-free sensing camera used to watch molecules bind in many channels at once. Standard wavelength-swept systems need pricey tunable filters. Their rig swaps them for five light-emitting diodes spanning the needed colors and a smart fitting routine.
The routine scans coarsely, then picks the best three diodes for a fine fit, rebuilding the resonance position with no moving parts. A full cycle takes about a tenth of a second with fine resolution. It tracked antibody binding live and read a cartilage wear marker in joint fluid, elevated in an arthritis sample as expected.
