The gel swelling solution is widely used in the preparation of polyacrylamide gels for electrophoresis, an important technique in molecular biology and biochemistry for separating proteins or nucleic acids by size. It enables the gel matrix to expand uniformly, creating the desired pore sizes for efficient separation. This solution is also utilized in drug delivery systems, helping to control the release rate of key drug components by modulating the swelling behavior of hydrogels. In the cosmetics industry, it enhances the texture and stability of products such as creams and lotions by improving water retention properties. Additionally, it is applied in agriculture as a soil conditioner, increasing soil water retention and promoting plant growth in arid areas.
