Researchers from the University of Glasgow have found a way to make swallowable cameras more effective at detecting cancers of the throat and gut.
In recent years, tiny sensing systems small enough for patients to swallow have proven to be a valuable clinical alternative to more intrusive imaging methods such as endoscopes.
Until now, the systems, often known as video-pill, have relied on illuminating patients' innards using a small light source, restricting clinicians to conclusions based on what they can see in the spectrum of visible light.
In a new paper published today (Friday 18 December) in the journal Scientific Reports, researchers from the University's School of Engineering describe how they have used fluorescent light for the first time to expand the diagnostic capabilities of the video-pill.
