Pocket-Sized Fluorometer Matches Lab Accuracy for Cancer and HIV Detection
Researchers at the University of Illinois Urbana-Champaign have developed a handheld device called the VPodDuo that performs fluorescence assays with accuracy comparable to expensive laboratory equipment. The device, roughly the size of an AirPod case, can detect pathogens like HIV and Zika, as well as cancer biomarkers including microRNA and circulating tumor DNA. Published in the IEEE Sensors Journal in July 2026, the technology aims to bring sophisticated diagnostics to home settings to enable earlier detection and preventable deaths. While the device has shown promising results in initial tests, it is not yet commercially available as researchers work on automating sample processing.
