A new flexible, low-cost biosensor that detects myoglobin—a crucial heart attack biomarker—has been developed by PhD scholar Mohsina Afrooz at BITS Pilani–Hyderabad and RMIT University, Australia. The graphene-based sensor quickly identifies myoglobin, a protein released soon after heart muscle injury. Early detection helps doctors spot cardiac events faster than traditional methods. Unlike expensive lab tests needing complex setups, this sensor is lightweight, flexible, and economical. It suits portable and point-of-care testing perfectly. Lead investigator Sanket Goel said, "The Indo-Australian collaboration focuses on translating advanced sensing technologies into affordable cardiac diagnostics. Our goal is to make early heart attack detection accessible, not just accurate." Associate investigator Sayan Das added, "Early detection saves lives only when it is affordable and deployable at scale." This technology could greatly help rural hospitals, emergency rooms, and low-resource healthcare centers where advanced equipment is rare. "It aims to make heart diagnostics faster, simpler, and more accessible to everyone," said Mohsina Afrooz. This research combines expertise from BITS Pilani–Hyderabad's MMNE Laboratory and RMIT University's Centre for Opto-Electronic Materials and Sensors. An Indian patent has been filed, highlighting its practical potential. The study was published in IEEE Sensors Letters on February 3, 2026.
