THE ONLY METAL THAT IS ANTI-BACTERIAL IS

• A. Iron
• B. Sodium
• C. Aluminium
• D. Copper ✓

The answer to the question is: D. Copper

The only metal that is antibacterial is copper. Copper has been known for its antimicrobial properties for centuries. It has the ability to kill a wide range of harmful microbes relatively quickly and efficiently, making it an effective tool in preventing the spread of infections. This unique property of copper has been extensively studied and utilized in various applications, such as in healthcare settings, food processing facilities, and public spaces.

Copper’s antimicrobial activity is attributed to its ability to disrupt the cellular processes of bacteria and other pathogens. When microbes come into contact with copper surfaces, the metal ions are released and interfere with the cell membrane, protein structure, and DNA of the microorganisms. This disrupts their normal functions and ultimately leads to their destruction. The effectiveness of copper against bacteria, viruses, and fungi has been well-documented through scientific research and practical applications.

In healthcare environments, copper surfaces have been shown to reduce the risk of healthcare-associated infections (HAIs) by continuously reducing microbial contamination on frequently touched surfaces. Studies have demonstrated that incorporating copper materials in hospitals, such as bed rails, door handles, and call buttons, can significantly lower the microbial burden and contribute to improved patient safety.

Furthermore, copper’s antimicrobial properties have also been recognized in food safety and preservation. Copper alloys are used in food processing equipment and food contact surfaces to help control the growth of bacteria and maintain hygienic conditions during food production and storage.

Overall, the antimicrobial efficacy of copper makes it a valuable material for various applications where controlling microbial contamination is crucial for public health and safety.
