Description
Akhil Chandrakanth Komaram and co-authors turn a phone camera into a lab reader in 2026 for interleukin-8, a signal of swelling tied to infection and cancer. Their card prints catcher antibodies in a two-by-five grid on glass. A drop of fluid lands on the card. Gold flecks tagged with a second antibody latch on where the target binds. The flecks tint the spot, and a phone photo plus free software scores the tint.
A drop of eight microlitres was all the test needed on the bench. It could find as little as 0.23 picograms per millilitre of fluid. Repeat reads varied by less than one percent. Spiked blood serum gave back 99.5 and 106.1 percent at the two levels tried. The authors offer the card as a cheap stand-in for plate tests.
