  2. Hydrogel dressing - Wikipedia

    en.wikipedia.org/wiki/Hydrogel_dressing

    Hydrogel dressing is a medical dressing based on hydrogels, three-dimensional hydrophilic structure. [1] The insoluble hydrophilic structures absorb polar wound exudates and allow oxygen diffusion at the wound bed to accelerate healing. [2]

  3. Self-healing hydrogels - Wikipedia

    en.wikipedia.org/wiki/Self-healing_hydrogels

    Self-healing hydrogels are a specialized type of polymer hydrogel.A hydrogel is a macromolecular polymer gel constructed of a network of crosslinked polymer chains. Hydrogels are synthesized from hydrophilic monomers by either chain or step growth, along with a functional crosslinker to promote network formation.

  4. Topical gels - Wikipedia

    en.wikipedia.org/wiki/Topical_gels

    Hydrogels can be used as drug delivery vehicles, for transdermal application, ophthalmic drug delivery, [11] cancer treatment [12] or for wound dressing. [7] [13] As a type of water based formulation, hydrogels are generally less greasy and are easier to be removed than oil-based formulations like organogels. [6]

  5. Self-healing material - Wikipedia

    en.wikipedia.org/wiki/Self-healing_material

    Hydrogels based on non-covalent interactions or dynamic covalent chemistry can exhibit self-healing properties after cutting or breaking. [137] Hydrogels that can fully fluidize followed by self-healing are of particular interest in biomedical engineering for the development of injectable hydrogels for tissue regeneration or 3D bioprinting inks ...

  6. Chitosan - Wikipedia

    en.wikipedia.org/wiki/Chitosan

    Chitosan is used within some wound dressings to decrease bleeding. [79] Upon contact with blood, the bandage becomes sticky, effectively sealing the laceration. [80] Chitosan hydrogel-based wound dressings have also been found useful as burn dressings, and for the treatment of chronic diabetic wounds and hydrofluoric acid burns. [3] [79]

  7. Povidone-iodine - Wikipedia

    en.wikipedia.org/wiki/Povidone-iodine

    A wound-healing application has been developed which employs a mat of single wall carbon nanotubes (SWNTs) coated in a monolayer of povidone-iodine. [ 24 ] Research has previously found that the polymer polyvinylpyrrolidone (PVP, povidone) can coil around individual carbon nanotubes to make them water-soluble.
