by Srinivas Rao : It’s really hard to believe how an obscure, creepy virus has put the entire world into panic and stress. Yes! This is a crucial period for all of us to stay safe, mentally strong and physically healthy. The pandemic has changed both work life and home life and this reminds us how cautiously we have to lead our lives.
The pandemic has taken a huge toll on our entire mankind, with still a few countries witnessing a rise in COVID-19 cases in which the numbers are increasing at an alarming rate.
While the entire world is anticipating for the vaccine to turn up, let’s not forget to follow the mantra of Chemistry to stay away from the virus.
- Wash hands frequently with an alcohol based hand sanitizer
Structure of Alcohols (Methanol, Ethanol, Propanol and Isopropanol)
Effect of Hand Sanitizer
Usage: For hands
Mechanism: Alcohol molecules dissolve the fatty outside layer of the virus and damage the structure of virus proteins by releasing their intracellular content.
2. On hard surface: Bleach Solution
Structure of Sodium hypochlorite
Usage: On hard surface. Minimum concentration of 0.1% bleach
Mechanism: Bleach oxidizes and destroys virus proteins and genetic material. It should be left on the surface for at least 10 minutes.
3. Washing hands frequently with soap and water
Effect of Soap
Usage: Wash hands for a minimum of 20 seconds
Mechanism: Soap molecules can dissolve the fatty outside layer of the virus and damage the structure of the virus protein by releasing intracellular content.
4. On hard surface: Hydrogen Peroxide
Structure of H2O2
Usage: On hard Surface
Mechanism: Peroxide oxidizes and destroys virus proteins and genetic material. It should be left on surface for at least 10 minutes.
As the whole world is anticipating the miracle of vaccines, we shall pledge to stick to the chemistry mantra, also to maintain physical distance, always wearing your face-cover/mask while in public and ensure it covers your nose and mouth properly.
