  • Can nonionic polyacrylamide be used as a gel fracturing fluid?
  • Nonionic polyacrylamide (NPAM) with controlled molecular weight was successfully synthesized as a gel fracturing fluid by aqueous solution polymerization.
  • What is immobilization in polyacrylamide gel?
  • Immobilization in polyacrylamide gel is a technique based on the polymerization of acrylamide with N,N′-methylene-bis-acrylamide (Bis) as the cross-linking agent. The degree of cross-linking is controlled by adjusting the ratio of acrylamide to Bis used. Being nonionic in nature, polyacrylamide is the most widely used matrix for entrapping enzymes.
  • Why do polyacrylamide and bis-acrylamide have different pores?
  • Due to complex interactions between samples, gel matrix, buffers and electric current, particles migrate at various rates based on their total charge, size and shape, resulting in distinct bands of individual molecules. By crosslinking polyacrylamide and bis-acrylamide, a network of pores is formed in the gel.
  • What is high molecular weight polyacrylamide (PAM)?
  • Provided by the Springer Nature SharedIt content-sharing initiative High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
