Tea brews up silver nanoparticles for wound healing in the developing world

Wound infections, particularly associated with burns, are a serious health problem causing high morbidity and mortality. Aside from hygiene and basic dressings, antibiotics are the standard treatment for serious wounds. However, cost, access, and emerging bacterial resistance, make their use difficult and ineffective, especially when a course of treatment is not completed. Globally, a huge number of deaths occur because of infected burns especially in low- and middle-income countries, and most commonly in rural areas.
