Panjab University Innovates Paint Additive to Combat Hospital Infections

Panjab University (PU) has made significant strides in public health by developing a paint additive designed to reduce hospital infections, a pressing concern heightened by the Covid-19 pandemic. This innovation, which received an Indian patent on December 31, 2025, aims to enhance safety in healthcare environments where the risk of infection is critical.

The research team, led by Gaurav Verma from the Department of Chemical Engineering and Nanotechnology, collaborated with colleagues Avneet Saini, Shubhi Joshi, and MSc student Deeksha Sharma. Their joint effort emerged as a response to the alarming rates of hospital-acquired infections observed during the pandemic, particularly during the delta wave in 2021-22.

The paint additive functions by effectively killing harmful bacteria on surfaces, thereby improving the safety of hospital walls, beds, and furniture. Importantly, the material is non-toxic and designed for indoor use, meaning it does not disperse into the air or surroundings, ensuring a safe environment for patients and healthcare workers alike.

Addressing a Growing Concern

The genesis of this innovation can be traced back to 2018 when Shubhi Joshi, a food microbiologist, approached Verma for a PhD opportunity. Despite excelling in the PU PhD entrance test, she faced challenges in securing admission in her desired subject. Verma recognized her potential and welcomed her into his lab to tackle a complex research problem focused on nanomaterials.

As the Covid-19 pandemic unfolded, the research team adapted to the circumstances by continuing their work in the laboratory while adhering to safety protocols. Their perseverance culminated in the successful development of the antibacterial paint additive, which was finalized in 2022.

Impact on Healthcare

The implications of this patented technology extend beyond aesthetics; it represents a proactive approach to infection control in healthcare settings. Hospital-acquired infections have been linked to severe complications, including conditions like black fungus, which have claimed numerous lives during the pandemic.

Verma emphasized the importance of this innovation, stating that science should directly benefit society. He believes that paints should not only enhance the visual appeal of buildings but also contribute to saving lives. Currently, Shubhi Joshi continues her research as an ICMR Woman Scientist, collaborating with the PU team to further advance their findings.

The potential for widespread application of this technology in hospitals and clinics signifies a proactive step towards improving patient safety and reducing infection rates in healthcare facilities. As the world continues to navigate the challenges posed by infectious diseases, innovations such as this one may play a crucial role in safeguarding public health.
