Cuprous oxide is a monovalent copper oxide which is a bright red powdery solid which is hardly soluble in water and is converted to divalent copper in an acidic solution. It is an important P-type semiconductor material with a band gap of only 2.1eV and a photoelectric conversion efficiency of 18%. In 1998, cuprous oxide

According to a large number of animal model experiments, nano-copper powder can significantly increase bone density, increase flexural strength, improve tissue morphology, and have significant preventive and therapeutic effects on osteoporosis. In particular, the treatment of fractures caused by osteoporosis significantly shortens the fracture healing period. The mechanism of action is unique, and its effects
