Hello, I am currently working on a bachelors thesis based on interfacial gelation and I am using Sodium Alginates. I know that when reacted with a calcium solution that the Alginates undergo a cross-linking reaction with the calcium to form a hydrogel. However, I would like to be able to use an amphiphilic molecule. If anyone knows of any amphiphilic molecules that are divalent and can also cross-link with sodium Alginate that would be great. I've spent a fair amount of time googling for some answers but to no avail. If anyone has any suggestions that would be great.

Thanks

What about a bis-quaternary ammonium compound? Like this onehttp://www.sigmaaldrich.com/catalog/product/sigma/h0879?lang=en&region=US&cm_sp=Insite-_-prodRecCold_xorders-_-prodRecCold2-2. Its hexane-1,6-bis(trimethylammonium bromide)

Oh, I'll look into that. Thanks a lot for the advice.
