BIOTOXICITAT

MATERIAL:
-Silver nanoparticles
-Sugar and yest
-Destilled water
-Hot place
-Ballon
-Spatula
-Pipet

PROCEDURE:
1. We take the nanoparticules of silver. The silver nanoparticules are toxics and damage the live cells.
2. We have three elermeyers: in the firt elermeyer we put sugar, yest and water. In the second elermeyer we put sugar, yest, water and 1ml of silver. And in the third elermeyer we put water, sugar, yest and 3ml of silver.
3.Then we put the elermeyers in the hot place with one ballon clousen the elermeyer.

CONCLUSION:
We see that the experiment procedure CO2 and we see that the ballon inflate,

QUESTION:
Why not inflate the last ballon?
Because the nanoparticules of silver kill the yest.
