2. Hydrogel - Wikipedia

   en.wikipedia.org/wiki/Hydrogel

   A hydrogel is a biphasic material, a mixture of porous and permeable solids and at least 10% of water or other interstitial fluid. [1] [2] ... A good balance ...

3. List of soft contact lens materials - Wikipedia

   en.wikipedia.org/wiki/List_of_soft_contact_lens...

   made of soft, flexible plastics that allow oxygen to pass through to the cornea. Soft contact lenses may be easier to adjust to and are more comfortable than rigid gas permeable lenses. Newer soft lens materials include silicone-hydrogels to provide more oxygen to your eye while you wear your lenses. [4]

4. Contact lens - Wikipedia

   en.wikipedia.org/wiki/Contact_lens

   In 1998, the first silicone hydrogel contact lenses were released by Ciba Vision in Mexico. These new materials encapsulated the benefits of silicone which has extremely high oxygen permeability—with the comfort and clinical performance of the conventional hydrogels that had been used for the previous 30 years. These contact lenses were ...

   Scientists discovered a way to take injections for popular GLP-1 drugs for diabetes and weight loss down from daily or weekly to just three a year.

6. Polyhydroxyethylmethacrylate - Wikipedia

   en.wikipedia.org/wiki/Polyhydroxyethylmethacrylate

   Poly(2-hydroxyethyl methacrylate) (pHEMA) is a polymer that forms a hydrogel in water. Poly (hydroxyethyl methacrylate) (PHEMA) hydrogel for intraocular lens (IOL) materials was synthesized by solution polymerization using 2-hydroxyethyl methacrylate as raw material, ammonium persulfate and sodium pyrosulfite (APS/SMBS) as catalyst, and triethyleneglycol dimethacrylate (TEGDMA) as cross ...

7. Hydrogel agriculture - Wikipedia

   en.wikipedia.org/wiki/Hydrogel_agriculture

   Common hydrogel agriculture's ingredient is potassium polyacrylate or sodium polyacrylate. As a superabsorbent material, it can absorb plenty of water and turn water to gel to store water. Hydrogel agriculture technology uses insoluble gel-forming polymers to improve the water-holding properties of different soils, such as clays and sandy loams.

8. 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.
