Nano Gel

The third type of nanomaterial is in the form of a gel, which is a form of providing nanomaterials between colloids and powder. In this case, the nanoparticles are practically dispersed in a small volume of solvent and create special properties.

In other words, it is a solid gel that can be displayed from soft and weak to hard and hard.

Gels are defined as a substantially dilute cross-sectional system that does not flow in a stable state. In terms of weight, the gels are mostly liquid, but because they have a three-dimensional cross-network within the liquid, they behave like solids. It is the interconnection inside the liquid that gives the gel its structure (hardness) and helps it stick. Thus, gels are the dispersion of the molecules of a liquid in a solid medium. The word gel was coined by 19th-century Scottish chemist Thomas Graham to cut off gelatin. This form of nanomaterials is used in pharmaceuticals and pharmaceuticals, gas sensors and building materials.
