Hydrogel has many uses in the medical and scientific worlds and can come in a variety of forms. The primarily water-based compound is often paired with other compounds or elements to produce an array of products. Hydrogel is commonly found in wound-healing products, contact lenses and has potential to play a major role as a drug-delivery agent, according to a report published by "Agricultural Research." Hydrogel ingredients can vary based on its form and for what application it is to be used.
Hydrogel Monomers
The monomers methacrylate and ethyleneglycol bismethacrylate form the hydrogel copolymer that is used in the production of soft contact lenses and as a drug-delivery agent, according to the Institute of Physics. Hydrogel made from soybean oil forms a durable polymer that reacts to changes in temperature or acidity level, according to the publication "Agricultural Research." Such characteristics make the hydrogel ideal for drug-delivery, as well as wound-dressing. The soybean oil hydrogel is also biodegradable and, therefore, does not pose an environmental problem unlike other forms of hydrogels.
Gelatin-based Hydrogels
The cross-linking of partially oxidized dextrans and gelatin hydrogel are the common compound in wound-dressing products, according to the Institute of Physics. Such products promote tissue development by keeping the wound area moist, yet protected from other topical elements. Gelatin hydrogels can be used to treat open cuts and bruises, as well as first and second degree burns and some ulcers.
Covalent Hydrogels
Japanese researchers recently developed a self-healing hydrogel. The product consists of 98 percent water and has minimal traces of sodium, polyacrylate and the branched molecule known as "G3-Binder," according to the Royal Society of Chemistry. The hydrogel has been compared to silicone rubber, as the material is very strong and durable. The material is also able to repair itself after being cut with a razor. Based on the hydrogel's developers, the material could be applied in organic synthesis, regenerative medicine and artificial cartilage.
