I'm working with nanoparticles (NPs) and I want to know what kind of starch I can use as a capping agent.
Check with guy he has worked on nanoparticles

Dear Tatiana,
i believe it would depend on the type of nanoparticles you are preparing. If they are hydrophobic, then you may use a modified starch which contains hydrophobic chains, there is a supplier, Makymat which produces one, is called Emcap. On the other hand, if your particles may be attracted to charged molecules, you may want to use cationic starch.
Best regards,

Hello Margarita
Well, I want it with hydrophilic behavior.. Becaouse I read some article, but in that, they didn't tell what kind of starch they used.
As Margarita Sanchez said, that it depends on the nature of the nanos you prepare. For nano-based transition metals, cationic starch is the most favorable while in the case of nanostructured oxides starch must be anionic.
Thanks you very much, I will check it .. and Hasna, I'm going to do silver nanoparticles.
Kiruba, actually I already had that paper ... no matter, thank you again, I will check your link ;)
You can use any type of starch, some are more or less soluble, though.
ok.. indeed, I will use soluble starch :) I hope that it works.
