gélek
Gélek, the plural form of the Hungarian word gél, refer to gels in general. In scientific terms, gels are semi-solid substances formed when a three-dimensional network of polymers entraps a large amount of liquid, typically water, giving a material that behaves as a solid but can deform like a liquid. They occupy a state between liquids and solids and are distinguished from simple emulsions or suspensions by their continuous, interconnected network.
Gelation can occur through chemical crosslinking, where covalent bonds join polymer chains, or through physical crosslinking,
Gels are diverse and widely used. Hydrogels contain mostly water and are common in biomedicine and tissue
Common laboratory and industrial gels include gelatin, agarose, alginate, and polyacrylamide gels, the latter frequently used
