Tiny probe set to shed light on lung disease

18 June 2019

A hair-sized probe that can measure key indicators of tissue damage deep in the lung has been developed by scientists.

The new technology could pave the way for accurate monitoring of tissue in areas where existing technologies cannot reach.

Experts say the probe can pick up tiny changes in tissue health and could improve how patients are assessed and treated, specifically those on ventilators in intensive care.

Pneumonia infection

Lung diseases are one of the leading causes of death and disability in the world. Despite significant advances, little is known about how disease develops in patients suffering from pneumonia or lung injury.

A team of scientists developed the probe, which comprises an optical fibre about 0.2mm in diameter that holds 19 sensors.

Lung sensor

Each sensor can measure different indicators in tissues, such as acidity and oxygen levels, which provide important information on the body’s reaction to disease processes.

Researchers have designed the technology to offer fast, accurate measurements and the flexibility to add more sensors.

Inflammatory diseases

Experts say the technology is widely applicable to other regions of the body and could be used to aid the understanding of inflammatory and bacterial diseases.
