Hi, my name is Maha Ali and I'll be talking about my project:
The Effects of Anatase Titanium Dioxide Nanopowder on Regeneration in Dugesia tigrina
To start off, I was putting on my makeup one day
when I wanted to know what the main ingredient was
and that was Titanium Dioxide
and that Titanium Dioxide was labeled as a possible carcinogen
and it is used daily in cosmetics, sunscreen, toothpaste, and paint
at the same time I was studying regeneration
which is the process of regrowth
an as humans we regrow our liver and skin cells
and starfish, hydra, and planarian regrow their limbs
I used Planarian as my model organism
because it's a great organism to see macroscopic effects
I had an experimental group and a control group
in my control group all I fed was a hard-boiled egg yolk
and in my experimental group
I fed both the Titanium Dioxide and the egg yolk
So after 3 weeks I decided to decapitate them.
And I was measuring them daily
I saw that there was a massive change between the different lengths
The control groups lengths were increasing
while the experimental groups was decreasing
I came to a conclusion that TiO2 can possibly
have an effect on the Planaria and have an effect on us
Today I still look for products that don't and do use TiO2
