Low-cost screen-printed carbon sensors have been used to rapidly detect bacteria commonly found in wounds, which could pave the way for a real time medical device.

A study carried out by the University of Strathclyde and NHS Ayrshire & Arran used sensitive portable electrochemical sensors, which detected infections in clinical samples within half an hour, much quicker than current hospital laboratory testing.

The detection of infection in clinical practice can be expensive and typically takes at least 48 hours for gold-standard laboratory methods of wound infection detection and bacterial identification.

In a collaboration with NHS Ayrshire & Arran clinicians, dressings and swabs were collected from patients with diabetes-related foot ulcers at University Hospital Ayr. These samples were then measured at the University of Strathclyde using the novel sensor, which revealed that the presence of bacterial infection…
