Panjab University Scientists Create Innovative Paint Additive to Combat Hospital Infections

Panjab University (PU) scientists have developed a groundbreaking paint additive that has the potential to significantly reduce infections in hospitals. This innovation comes at a time when hospital-acquired infections have become a pressing concern, particularly in the wake of the Covid-19 pandemic. The paint additive received an Indian patent on December 31, 2025, marking a major milestone in its development.

The research team, led by Gaurav Verma from the Department of Chemical Engineering and Nanotechnology, included Avneet Saini from the Department of Biophysics, Shubhi Joshi, and MSc student Deeksha Sharma. Their collaborative efforts during the pandemic focused on addressing the urgent need for safer hospital environments. This new additive actively kills harmful bacteria on surfaces, enhancing the safety of hospital walls, beds, and furniture.

The significance of this innovation is underscored by the rise of hospital-acquired infections, especially during the delta wave of Covid-19 from 2021 to 2022. These infections often spread through contact with surfaces, leading to serious complications, including cases of black fungus. The researchers aimed to create a non-toxic solution that does not disperse harmful materials into the air, making it safe for indoor use.

From Concept to Reality

The idea for the paint additive began in 2018 when Shubhi Joshi, a food microbiologist, approached Gaurav Verma for her PhD. Despite her impressive results in the PU PhD entrance test, she faced challenges in securing admission in her preferred subject. Verma welcomed her into his lab, presenting her with a complex research problem involving nanomaterials.

During the pandemic, the team continued their work while adhering to safety protocols. Their dedication culminated in the successful development of the antibacterial paint additive, completed in 2022. Currently, Shubhi Joshi is an ICMR Woman Scientist and maintains her collaboration with the PU research team.

Verma emphasized the broader implications of their work, stating that “every student has the ability to do meaningful science” and that scientific advancements should directly contribute to societal well-being. He believes that paints should serve a dual purpose: enhancing the aesthetic appeal of buildings while also playing a crucial role in saving lives.

This innovative paint technology holds great promise for hospitals and clinics worldwide, potentially leading to safer healthcare environments and improved patient outcomes. As healthcare systems continue to grapple with infection control, this development represents a significant step forward in the fight against hospital-acquired infections.
