Indian researchers develop diagnostic device to detect early-stage bone cancer
New Delhi: In a major scientific breakthrough, researchers from IIT (BHU) in Uttar Pradesh have developed a miniaturised, self-reporting diagnostic device that can detect early-stage bone cancer with high precision.
The first-of-its-kind sensor detects osteopontin (OPN) -- a key biomarker for bone cancer.
The device is reagent-free, portable, and cost-effective and is ideal for rural healthcare, said the research team led by Dr. Pranjal Chandra from the School of Biochemical Engineering.
The device works much like a glucose metre and enables quick, accurate, and on-the-spot detection, even in resource-limited settings.
The device uses a custom sensor surface composed of gold and redox-active nanomaterials, allowing it to function similarly to a glucose meter.
'This technology simplifies cancer detection and empowers primary health centres,' said Prof. Chandra. The findings are published in the prestigious journal Nanoscale (Royal Society of Chemistry, UK).
OPN is a crucial biomarker associated with osteosarcoma -- a highly aggressive form of bone cancer that primarily affects children and adolescents.
While current methods to detect OPN are costly and time-consuming, the new device offers rapid and accurate results with minimal equipment.
It is designed as a reagent-less immunosensor, which enables on-the-spot and affordable testing. It is especially beneficial in rural and resource-constrained areas where early cancer detection is often delayed.
Cancer is a major public health concern in India, with rising incidence rates and significant mortality.
Lauding the innovation, Director Prof. Amit Patra called it 'a prime example of technology with a human face'. He said it contributes to precision medicine and national health priorities. He added that the innovation aligns with the government's Make in India and Start-up India initiatives.
A patent application has been filed, and efforts are underway to convert the prototype into a smartphone-compatible diagnostic kit for remote healthcare access, the researchers said.

IIT-Madras eyes global top 50 with major expansion plans
NEW DELHI: Indian Institutes of Technology and IISc are unlikely to break into the list of world's top 50 universities unless they run full-fledged medical colleges, IIT-Madras director Professor V Kamakoti has said, revealing that the institution is considering setting up a medical college to overcome this gap in its portfolio. In an exclusive interaction with TOI, Kamakoti said IIT-M has already begun internal discussions on establishing a medical college, which would be integrated with its engineering and science departments, as part of its long-term vision, and is looking for a large hospital. Further, the institution has planned a global outreach through its proposed research centres in Dubai, Malaysia, and Germany and a sustainability campus in Puducherry, another important parameter for global rankings that Indian institutions lag on. In what's an unconventional move, IIT-M has formalised a platform to help its students prepare for civil services exams. 'If you want to come into top 50 (in global rankings), you must have a medical school,' Kamakoti stressed, adding, 'The top-ranked universities all have global campuses, deep-research collaborations, and, critically, medical schools'. He added: 'This is not just about rankings — it's about enabling convergence in areas like AI in healthcare, biomedical engineering, and public health. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like 새로 나온 '실손보험' 최적가 비교가입!

On the plan for developing a sustainability-focused campus in Puducherry, the director said, 'This campus will be a living laboratory for climate, water, and energy research'. Explaining the move, he added: 'Sustainability is now a global benchmark in rankings. That's why we've started School of Sustainability under School for Interdisciplinary Studies. It's aligned with the UN's Sustainable Development Goals. Every project must resonate with these goals — from green tech to zero-emission housing. Auroville collaborations in Puducherry are a part of this vision'. To expand global footprint, the institution will go for research collaborations and set up satellite centres in Dubai, Malaysia, and Germany. These will encourage Indian researchers to work on global problems and offer Indian students cross-border learning. 'It's called IITM Global,' Kamakoti said, detailing the vision behind the international outreach. 'If you solve an issue for India, you've solved it for the world. Our IITM Global will take these to Malaysia, Germany, Dubai (by this academic year), and beyond.' Kamakoti also highlighted IIT-M's initiative to nurture engineers for civil services. To enable this, institute has created Pragati, a platform to guide and support UPSC aspirants on campus. 'We want our students to start early — during BTech or MTech — with structured preparation, peer interactions, and access to faculty and civil servants who've walked that path,' he said. 'We're not just a tech school anymore — we're shaping India's future in several ways,' Kamakoti summed up.
