hydrogel

 [hi´dro-jel]
a gel that contains water.

hy·dro·gel

(hī'drō-jel),
A colloid in which the particles are in the external or dispersion phase and water in the internal or dispersed phase. Compare: hydrosol.

hydrogel

Wound care A polymer absorptive wound dressing. See Dressing.

hy·dro·gel

(hī'drō-jel)
A colloid in which the particles are in the external or dispersion phase and water in the internal or dispersed phase; used in sterile dressings and wound cane.

hydrogel

Type of plastic material which contains water, and is commonly used in the manufacture of soft contact lenses, e.g. HEMA.
