In a major leap for cancer diagnostics, researchers at the Indian Institute of Technology (BHU), Varanasi, have developed a miniaturised, self-reporting bioelectronic device that can detect early-stage bone cancer with remarkable sensitivity. This innovation could significantly improve early diagnosis, especially in rural and underserved areas.
Targeting a Key Biomarker in Osteosarcoma
As reported by TOI, the device detects Osteopontin (OPN), a vital biomarker linked to osteosarcoma. This aggressive form of bone cancer commonly affects children and adolescents. By focusing on this biomarker, the device offers an efficient and reliable method to identify the disease at an early stage.
Simplifying Cancer Detection
Published in Nanoscale, a journal by the Royal Society of Chemistry, the study highlights how this reagent-less immunosensor eliminates the need for expensive lab reagents and complex procedures. The device functions similarly to a glucose meter and delivers instant results. It uses only a buffer solution, with no chemical mediators required.
Innovative Design for Accessible Testing
The research team, led by Prof. Pranjal Chandra from the School of Biochemical Engineering, includes scholars Daphika S Dkhar and Supratim Mahapatra. They designed the sensor surface using gold and redox-active nanomaterials to allow rapid, on-site detection. “Its simplicity and portability make it ideal for primary healthcare centres,” said Prof. Chandra.
A Step Toward Smartphone-Based Diagnostics
Conventional OPN tests are often costly and time-consuming. In contrast, this device provides a quick, affordable, and accurate alternative using minimal equipment. A patent has already been filed. The team is now working on converting the prototype into a smartphone-compatible diagnostic kit for remote, widespread healthcare use.
Aligning with National Innovation Goals
IIT (BHU) Director Prof. Amit Patra praised the team’s efforts. He stated that the innovation reflects the vision of India’s Make in India and Start-up India initiatives. He described the device as an example of “technology with a human face,” advancing the cause of precision medicine in India.
