Researchers at Oxford University have developed a diagnostic instrument driven by artificial intelligence that can detect known respiratory infections in only five minutes using a single sample taken from the nasal passages or the throat.

Existing techniques that can only identify a specific infection, such as a COVID-19 lateral testing apparatus, or which are neither research facility nor labor-intensive nor rapid but less accurate may be rendered obsolete by the innovative diagnostic test.

Nicolas Shiaelis, a DPhil student, Prof. Achilles Kapanidis from the Physics Department & Dr. Nicole Robb from Warwick University who represents as a visiting scholar at Oxford's Physics Department, describe the new method for detecting and identifying viruses in a paper that was published in ACS Nano.

The research demonstrates how machine learning has the potential to significantly improve the rate, accuracy, and efficacy of not just categorizing viruses but also distinguishing across strains of the same virus.

Validation of the unique technique was a collaborative effort between the John Radcliffe Hospital, led by Dr. Robb, and Nicolas Shiaelis. The novel testing technique combines small molecule labeling, computer vision, and machine learning to produce a universal medical diagnostic platform. 

This platform can swiftly detect the pathogen in a patient sample simply by looking straight at it. The concept is comparable to software that recognizes facial features, except that it does so for germs.

Studies conducted first showed that the test was able to notice the COVID-19 virus in patient samples. Studies conducted afterward demonstrated that the test could diagnose different respiratory infections in 5 minutes with an average accuracy of over 97%.

Dr. Robb and Nicolas Shiaelis, co-founders of the Oxford University spinoff business Pictura Bio, are in charge of licensing the technology. They are presently trying to get more financing to expedite research and move it to the center of healthcare.

According to Dr. Robb, "Cases of respiratory infections have touched record-breaking highs this winter," which has led to an increase in the number of persons seeking medical assistance.

This, in conjunction with the COVID-19 congestion, understaffing, reduced resources, and an aging population, places an enormous and unsustainable amount of strain on the National Health Service and its personnel.

Our streamlined approach to diagnostic testing is not only speedier but also more cost-effective, more accurate, and more prepared for the future than any other tests that are now on the market.

 Instead of developing a whole new test, all that is required of us to identify a newly discovered virus is to retrain the software to recognize it. Our research demonstrates that this technology has the potential to revolutionize viral diagnosis as well as our capacity to prevent the spread of respiratory infections. Robb added.
