Description and Uses

Sodium Acrylate (SA) is a sodium salt of acrylic acid with antibacterial properties. Sodium polyacrylate is a sodium salt of a polymer consisting of acrylic acid, methacrylic acid or one of their simple esters. SA can be used in tuning the grain size of iron oxide microparticles for potential applications in biological assaying and in chemical sensors. Additionally, it acts as a reducing and capping agent for gold nanoparticles, beneficial for various biological applications.
