How an IIT Delhi Scientist Is Using Patented Nanotech to Keep Your Water Tanks and Mattresses Germ-Free

In a country where water contamination and hygiene-related illnesses are still rampant, one woman scientist is leading a quiet revolution—using science to keep our everyday products safe and bacteria-free. Meet Dr Anasuya Roy, a PhD from IIT Delhi, whose patented technology is now making a real-world difference in the fight against harmful microbes.

Dr Roy’s innovation began as part of her doctoral research on nanomaterials and antimicrobial properties. What emerged was a unique, copper-based active technology that could inhibit the growth of bacteria, fungi, and viruses on multiple surfaces. Recognizing its vast potential, she launched her startup, Nanosafe Solutions, with a mission to translate lab science into everyday hygiene applications.

Her patented antimicrobial tech involves embedding active copper particles into products like water tanks, mattresses, cosmetic packaging, water bottles, textiles, and even industrial polymers. The result? Surfaces that are inherently hostile to microbial colonization—reducing the risk of contamination, odour, stains, and infections.

What sets this technology apart is its safety, sustainability, and scalability. Unlike chemical disinfectants that degrade over time or cause side effects, Nanosafe’s copper-based materials are stable and non-toxic, offering long-term protection with minimal environmental impact. In fact, the materials used are RoHS (Restriction of Hazardous Substances) compliant and meet global health and safety standards.

Over the last few years, Nanosafe has gained attention not only for its innovative technology but also for its real-world applications across sectors. From consumer-grade water bottles to large-scale manufacturing of antimicrobial fabrics, the startup is now collaborating with various companies to embed this technology into their supply chains.

Dr Roy’s journey is also symbolic of a larger shift—encouraging more women in STEM to take their research beyond academia and into entrepreneurship. “The idea was always to create impact, not just publish papers,” she says.

As the world becomes increasingly hygiene-conscious post-COVID, and with India pushing for domestic innovations under the Make in India and Startup India campaigns, Nanosafe Solutions stands as a perfect example of science-driven entrepreneurship. By combining innovation with practicality, Dr Anasuya Roy has not only solved a critical problem but also inspired a new wave of research-led startups in India.

With use cases spanning water purification, healthcare, hospitality, and home products, her copper-based tech could very well be a defining hygiene innovation of the decade.
