10 thoughts on “D83 – Remer

    1. Thankyou for your comment! The reason that nanoparticles don’t form a precipitate is because they don’t have a charge so it doesn’t react with the media which means a precipitate won’t form.

  1. Nice presentation! In your opinion, would the silver nitrate or silver nanoparticles be more promising for future research?

    1. Thankyou for the comment! This is a really hard question because both are very similar in the way they work but in my opinion using silver nitrate would be more promising if the issue with the precipitant can be fixed. Which we believe can be fixed by using a different type of media that silver nitrate won’t fully react with.

  2. I enjoyed watching your presentation! Why do you think only a small concentration of silver nitrate is toxic to bacteria? What is the mechanism behind this?

    1. Thankyou for watching the presentation! The reason small concentrations of silver nitrate are toxic is because they are known to be a poison so it doesn’t take much to kill bacteria and it does this through the silver ions which will block the bacterial respiratory system and thereby destroy the energy production of the cell.

  3. What made you choose silver nitrate to experiment on? I’ve never heard of it being used to killed bacteria before.

    1. Thanks for the comment! The reason we chose silver nitrate is because it has been known to kill at low concentrations which is a good sign since the lower the concentration we can use the better it is for humans.

  4. What is the difference in toxicity between silver nitrate and silver nanoparticles to bacteria?

    1. Thanks for the comment! Nanoparticles would be considered less toxic and better for humans than silver nitrate because silver nanoparticles are capped with plant extract. This makes them more stable and nontoxic to human tissue.
