In ancient Egypt, life after death was an enormous part of the Egyptian life. Thus the protecting bodies from decay and preserving them in a recognizable form was extremely important for the ancient Egyptians, who believed that people needed their bodies in the afterlife. From  here started the mummification process, embalming and treating a dead body after death in ancient Egypt removed the internal organs from an incision on the left side of the mummy body, and covered with plate from copper or  copper alloys. The results reveal that decorated bronze plate was used for protection and fights the decay of mummy body from microbial and fungal. Copper ions, either alone or in copper complexes, have been used for centuries to disinfect liquids, solids and human tissue. This manuscript explain the antibacterial mechanisms of bronze and the current usages of copper and copper alloys as antibacterial and antifungal by the ancient Egyptian to protect the body of mummies from decay. The study results suggest  the selection of copper and tin alloy (bronze) plates can materially assist in reducing the transmission of infectious organisms and consider as  excellent antibacterial action against several type of bacteria such as Bacillus, Pseudomonas and E. coli.
