Copper handles can kill bacteria

Japanese researchers have tested the pull rings on buses in Tokyo and found that plastic and leather pull rings have a large number of bacteria, while copper pull rings have no bacteria.

Some people like smooth and beautiful stainless steel door handles, saying that stainless steel also has a bactericidal effect, which should be no problem, but the actual result is not like that. According to testing results by American researchers, although stainless steel performs better than plastic and leather materials, it still breeds thousands of bacteria, including Escherichia coli, Gram bacteria, and Streptococcus.

The researchers conducted the same test on the brass handle again, and the results were surprising: the bacteria on the brass handle were almost zero. Researchers tested the rate at which bacteria on copper were killed and found that all bacteria on yellow copper were completely eliminated within 7 hours. On the newly polished brass surface, the speed at which bacteria are annihilated is even more astonishing, taking only 15 minutes.

The application of copper in medical institutions

It is precisely because copper has a strong bactericidal effect that door handles, faucets, and handrails in public places, hospitals, bathrooms, and other areas in the United States are currently made of copper, which can effectively ensure a good public health environment. Especially in medical institutions, the bactericidal effect of copper has been applied earlier and more widely. Such as widely used disinfection basins, catheters, tongue depressors, contraceptive devices, etc. in clinical practice. Especially in hospital wards, operating rooms, observation rooms, toilets, restrooms, corridors, stairs, and other areas, using copper utensils is more conducive to safety than using other materials.

More general applications of copper's bactericidal effect

In recent years, the application of copper's bactericidal effect has become increasingly widespread, and corresponding products are also increasing. Especially with the use of copper fiber to make socks, suspender socks, bed sheets, towels, underwear, masks, rags, as well as air conditioning filter paper, water purifiers for water pipes, shower heads, sink faucets, etc., the sterilization function of copper is being accepted by more people and widely used in daily life.
