• Abstract:

  I. Background: Photocrosslinked polyacrylic acid (PAA-HEMA) hydrogel is a promising candidate for use in dermatological patch adhesives. The hydrogel retains a large amount of water while maintaining sufficient mechanical strength. The gel characteristics can also be varied over a wide range by controlling the formulation factors. However, the..
