Panjab University scientists have created a special paint additive aimed at lowering infections in hospitals, a critical concern post the Covid-19 outbreak. This innovation secured an Indian patent on December 31, 2025.
Led by Gaurav Verma from the Department of Chemical Engineering and Nanotechnology, the breakthrough stemmed from collaborative research during the Covid-19 crisis. The team also includes Avneet Saini from the Department of Biophysics, Shubhi Joshi, and MSc student Deeksha Sharma.
The newly developed paint additive functions by eradicating harmful bacteria on various surfaces, enhancing the safety of hospital walls, beds, and furniture. Notably, this material is non-toxic and does not disperse into the air or surroundings, ensuring safe indoor usage.
This patented paint technology holds promise for widespread application in hospitals and clinics to mitigate infections and enhance patient safety. The concept evolved in response to the surge in hospital-acquired infections, particularly during the delta wave of 2021-22, which claimed numerous lives.
The inception of this innovation traces back to 2018 when Shubhi Joshi, a food microbiologist, approached Gaurav Verma for a PhD opportunity. Despite facing admission challenges in her field, Verma welcomed her into his lab, assigning a research project involving nanomaterials. Throughout the pandemic, the team continued their work in the lab, adhering to Covid safety protocols and maintaining physical distancing.
Their dedication culminated in the successful development of the anti-bacterial paint additive by 2022. Presently, Shubhi Joshi serves as an ICMR Woman Scientist, collaborating with the Panjab University research team. Verma emphasized that this innovation underscores his belief in students’ capacity for impactful scientific contributions and the role of science in benefiting society. He stressed the importance of paints not only enhancing aesthetics but also playing a role in saving lives.
