  • How is polyacrylamide used in molecular biology?
  • Polyacrylamide is also often used in molecular biology applications as a medium for electrophoresis of proteins and nucleic acids in a technique known as PAGE. PAGE was first used in a laboratory setting in the early 1950s.
  • Can Resol crosslinked polyacrylamide hydrogel be used as chemical flooding agent?
  • Polymer Journal 42 , 357–362 ( 2010) Cite this article Resol crosslinked polyacrylamide (PAM) hydrogel can be used as the chemical flooding agent in enhanced oil recovery because of its excellent temperature- and salt-resistant properties.
  • Is polyacrylamide contaminated with acrylamide?
  • Polyacrylamide is of low toxicity but its precursor acrylamide is a neurotoxin and carcinogen. Thus, concerns naturally center on the possibility that polyacrylamide is contaminated with acrylamide. Considerable effort is made to scavenge traces of acrylamide from the polymer intended for use near food.
  • What is a crosslinked polymer?
  • Cross-linking can be introduced using N,N-methylenebisacrylamide. Some crosslinked materials are swellable but not soluble, i.e., they are hydrogels. Partial hydrolysis occurs at elevated temperatures in aqueous media, converting some amide substituents to carboxylates. This hydrolysis thus makes the polymer particularly hydrophilic.
