Panjab University Innovates Paint Additive to Combat Hospital Infections

Panjab University (PU) researchers have developed an innovative paint additive designed to significantly reduce infection rates in hospitals, addressing a critical issue that has gained prominence following the Covid-19 pandemic. This groundbreaking innovation received an Indian patent on December 31, 2025, marking a key milestone in the fight against hospital-acquired infections.

The project, spearheaded by Gaurav Verma from the Department of Chemical Engineering and Nanotechnology, emerged from collaborative efforts during the pandemic. The research team includes Avneet Saini from the Department of Biophysics, Shubhi Joshi, and MSc student Deeksha Sharma. Their additive is engineered to eliminate harmful bacteria on surfaces, enhancing the safety of hospital walls, beds, and furniture. Notably, the material is non-toxic, ensuring it does not disperse into the air or surrounding environments, making it suitable for indoor applications.

Addressing a Critical Need in Healthcare

The development of this paint technology comes in response to the alarming rise in hospital-acquired infections highlighted during the pandemic, particularly during the delta wave of 2021-2022. These infections, which often spread through frequently touched surfaces, were linked to severe complications, including cases of black fungus. The need for effective solutions has never been more pressing, as hospital settings can be breeding grounds for infections that threaten patient safety.

The concept for this innovation began in 2018 when Shubhi Joshi, a food microbiologist, sought to work under Gaurav Verma for her PhD, despite facing challenges in gaining admission to her preferred subject. Verma welcomed her into his lab, where she took on the intricate task of researching nanomaterials. The team’s commitment to their work persisted throughout the pandemic, as they adhered to safety protocols while continuing their research.

By 2022, their efforts culminated in the successful completion of the antibacterial paint additive. Currently, Joshi is affiliated with the Indian Council of Medical Research (ICMR) as a Woman Scientist and continues to engage with the PU research team, showcasing the enduring collaborative spirit of the project.

Impact on Future Healthcare Solutions

Verma emphasized the significance of the innovation, stating, “I believe every student has the ability to do meaningful science, and that science should directly help society.” He highlighted the potential of paints to serve not only as aesthetic enhancements for buildings but also as vital tools in saving lives.

The potential applications of this patented paint technology extend beyond hospitals, suggesting a broader impact on healthcare facilities. As healthcare providers seek new ways to protect patients and staff from infections, this paint additive represents a promising step forward.

In summary, the work conducted at Panjab University reflects a proactive approach to addressing a pressing global health challenge, showcasing the importance of scientific innovation in enhancing public safety and improving patient care in medical environments.
