US-based Nigerian scholar Dr Fahad Usman develops innovative, non-invasive method for diabetes testing

By Uzair Adam

In a ground-breaking advancement for diabetes diagnostics, Nigeria-born Dr Fahad Usman, an Assistant Professor of Optical Engineering Technology in the United States, has introduced a highly sensitive optical biosensor capable of non-invasive diabetes screening.

Dr Usman’s pioneering work focuses on a surface plasmon resonance (SPR) biosensor that detects exhaled breath acetone, a key biomarker for diabetes. This innovative approach offers an alternative to traditional blood glucose tests, which are invasive and often painful.

Dr Usman’s research, published in top journals like Results in Physics and Polymers Journal, presents a novel ternary composite material made from polyaniline, chitosan, and reduced graphene oxide. With enhanced electrical conductivity and thermal stability, this material underpins the SPR biosensor, allowing it to detect acetone concentrations as low as 0.88 parts per billion. 

This collaboration with researchers from Malaysia, France, Saudi Arabia, and the U.S. addresses the global diabetes crisis. With over 537 million affected worldwide and projections of 783 million by 2045, this innovation promises a significant impact. According to the National Institutes of Health, over 37 million people in the U.S. are affected by diabetes. 

Due to its non-invasive nature, the optical sensor ensures greater accuracy, sensitivity, and reliability and enhances patient compliance. 

Dr Usman’s work represents a significant leap forward in healthcare innovation. It positions the U.S. at the forefront of global scientific advancements.

This technology offers potential beyond healthcare, with broader industrial applications in optical sensing and materials science.
