Hydrogels
By: Batool Murtaza Abstract Hydrogels have been around for almost half a century, and one of the oldest recordings of crosslinked hydroxyethyl methacrylate (HEMA) hydrogels dates back to the 1950s. Hydrogels continue to intrigue material scientists and biological researchers today, and significant progress has been made in terms of formulations and applications. Hydrogels are a type of material that consists of a self-supporting, water-swollen three-dimensional (3D) viscoelastic network that allows molecules and cells to diffuse and adhere. Hydrogels, on the other hand, have recently received a lot of attention for their usage in a wide range of biological applications, including cell therapies, wound healing, cartilage/bone regeneration, and medication sustained release. This is due to their biocompatibility and physical qualities that are similar to those of natural tissue. Based on ancient and new papers in this subject, this study attempts to provide an overview ...
