Revolutionary Eco-Friendly Antibacterial Material Targets Hospital Infections and Food Safety Risks

By Tosin Clegg

A groundbreaking antibacterial material developed by Nigerian chemist Philip Ugbede Ojo Onuche promises to reshape infection control in healthcare and food industries worldwide. The novel copper(I) oxide microsphere decorated cellulose “COMDC” nanocomposite, synthesized from eucalyptus pulp waste and stabilized using Schweitzer’s reagent, overcomes two long-standing challenges in nanotechnology: particle instability and potential toxicity.

“Copper-based antibacterial agents are effective, but instability and toxicity have always limited their safe application,” Onuche explained. “This innovation solves both problems, using waste-derived cellulose as a green stabilizer, making it safer for patients, workers, and the environment.”

The composite, which is undergoing the filing process as provisional patent with the United States Patent and Trademark Office, demonstrates exceptional antimicrobial activity against a wide spectrum of bacteria, including antibiotic-resistant strains. Laboratory tests show its potential in hospital surface coatings, medical devices, and food packaging, offering a sustainable and affordable alternative to conventional disinfectants.
Industry observers believe the breakthrough could reshape practices in multiple sectors.

According to experts, the innovation “brings together sustainable materials science and critical public health needs in a way that directly responds to two of today’s most urgent global challenges.”
Beyond healthcare, the nanocomposite could help reduce foodborne illnesses, improve shelf life for perishable goods, and support green manufacturing practices. Discussions are already underway with U.S.-based research partners to advance the material toward commercialization.

This innovation aligns with growing calls for eco-friendly industrial solutions that do not compromise effectiveness. If widely adopted, Onuche’s technology could redefine the standards for antibacterial safety in high-risk environments around the world.
