IIT Guwahati Successfully Establish A Cost-Effective Photodetector
The Indian Institute of Technology (IIT) Guwahati has made a significant breakthrough in healthcare technology. The researchers have lead the development of a revolutionary, with cost-effective photodetector. They have made it by using advanced materials and techniques. This innovation is based on promises to enhance medical diagnostics and monitoring.
A photodetector is a device that senses and converts light i.e. photons into an electrical signal. This device is basically used in various applications. It can be used as an optical communication, medical imaging, and environmental monitoring. They can also detect different wavelengths of light and are essential for technologies like cameras, solar cells, and sensors in various scientific and industrial fields.
The research was published in the prestigious ACS Applied Materials & Interfaces journal. It was co-authored by Professor P K Giri, Department of Physics, and his research scholars, Debabrata Sahu, Subhankar Debnath, and Sirsendu Ghosal, at IIT Guwahati.
Traditional photodetectors, are often used in medical imaging and diagnostics, can be prohibitively expensive. Due to this reason it limited their availability to well-funded institutions. In contrast, IIT Guwahati’s photodetector has the potential to democratize access to vital medical technologies, particularly in rural and underserved communities.

Speaking about the research, Prof. P. K. Giri, said, “Our goal was to create a photodetector that is not only highly efficient but also affordable and durable for real-world applications. By incorporating 2D printed plasmonic nanoparticles into the design, we have significantly enhanced the device’s performance while ensuring scalability and cost-effectiveness”, stated a press release.
The team used a specialised micro printing technique to precisely arrange the silver nanoparticles. This helped in improving the device’s sensitivity while making the manufacturing process scalable and economical. The photodetector remains stable under normal environmental conditions, ensuring durability for practical applications across various industries.
