Hydrogel can be prepared by mixing a monomer, such as acrylamide, with a crosslinking agent, like N,N'-methylenebisacrylamide, in the presence of a polymerization initiator, such as ammonium persulfate. The mixture is typically dissolved in water to create a gel matrix. Once combined, the solution is subjected to heat or UV light to initiate polymerization, forming a three-dimensional network. After polymerization, the hydrogel can be washed to remove unreacted components and excess initiators.
