Characterizing Viscoelastic Properties of Polyacrylamide Gels

The polymerization of a polyacrylamide gel is a free-radical catalyzed reaction and results in long chains that are held together by covalent bonds Polyacrylamide gels are typically made between two glass plates because oxygen acts a free-radical scavenger and inhibits polymerization ( [manual] 2005)
