Anwendung

  • 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).

Recently, layer-by-layer (LbL) assembly has emerged as a versatile, gentle and, simple method for immobilization of functional molecules in an easily controllable thin film morphology.1,2 In this short review, we introduce recent advances in functional systems fabricated by using the mild, yet adaptable LbL technique.

We present an article that discusses two applications in particular; first, using these layers as polyelectrolyte membranes to control permeability.
