Panjab University Team Creates Innovative Paint Additive to Combat Infections

Panjab University (PU) scientists have developed a groundbreaking paint additive designed to significantly reduce hospital infections, a pressing issue that has gained attention following the Covid-19 pandemic. The innovation was awarded an Indian patent on December 31, 2025, marking a significant advancement in healthcare safety.

The project was spearheaded by Gaurav Verma from the Department of Chemical Engineering and Nanotechnology, with contributions from Avneet Saini of the Department of Biophysics, Shubhi Joshi, and MSc student Deeksha Sharma. Their collaboration began during the pandemic, which highlighted the critical need for improved infection control in medical settings.

How the Paint Additive Works

The newly developed paint additive functions by actively killing harmful bacteria on various surfaces, including hospital walls, beds, and furniture. Its non-toxic formulation ensures safety for indoor environments, as it does not release harmful substances into the air. This innovative technology has the potential to be widely implemented across hospitals and clinics, contributing to a decrease in infections and enhancing patient safety.

The urgency of this development stems from the increasing rates of hospital-acquired infections, particularly during the delta variant surge in 2021-22, when many lives were lost. These infections often spread through contact with contaminated surfaces, leading to severe complications, including cases of black fungus.

A Journey of Collaboration and Innovation

The inspiration for this project traces back to 2018, when Shubhi Joshi, a food microbiologist, sought to pursue her PhD under Verma’s guidance. Despite excelling in the PU PhD entrance examination, she faced challenges in enrolling in her desired program. Verma welcomed her into his lab, presenting her with a complex research problem involving nanomaterials.

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

Verma emphasized the broader implications of their work, stating that it embodies his belief that every student has the potential to contribute meaningfully to science. He advocates for innovations that not only enhance aesthetic appeal but also prioritize public health and safety. The team’s work exemplifies how scientific advancements can directly benefit society, addressing critical health challenges in a post-pandemic world.
