Aplicación

  • Poly(acrylic acid) Hydrogel for Mucoadhesives: This study focuses on the radiation crosslinking of poly(acrylic acid) to create a bioadhesive hydrogel, which can be crucial for drug delivery applications, especially in mucoadhesive drug delivery systems (YC Nho, JS Park, YM Lim, 2014).
  • Hydrogel for Dye Removal: Development of a poly(acrylic acid) based hydrogel with fast adsorption rates and high capacity for removing cationic dyes, relevant for environmental cleanup and potentially for purifying biological fluids in pharmaceutical processes (Z Yuan, J Wang, Y Wang, Q Liu, Y Zhong, Y Wang, 2019).
  • Composite Hydrogels for Swelling Properties: Investigation into poly(acrylic acid-co-acrylamide) composite hydrogels, studying their swelling properties which are essential for understanding the behavior of hydrogels used in drug delivery systems and tissue engineering (WM Cheng, XM Hu, YY Zhao, MY Wu, ZX Hu, XT Yu, 2017).
