Natural disasters and violent conflict in low-income countries pose particular challenges for the sterilization of surgical instruments required for emergency medical procedures. SteriCell is a portable off-grid sterilization system that replaces large, heavy mains-powered hospital autoclaves that require plenty of clean water. A fuel cell is used to power the germicidal ultraviolet light that works in parallel with 10ml of nano titanium dioxide power, an antimicrobial technology that crystalizes titanic iron ore into a nano liquid when exposed to ultraviolet light and is two times stronger than chlorine.
