Electrophoretic mobility is a measure of the movement of charged particles in an electric field. It is influenced by the size, charge, and shape of the particles, as well as the properties of the surrounding fluid.
Electrophoretic mobility can be measured using techniques such as capillary electrophoresis or gel electrophoresis. In these methods, an electric field is applied to a solution containing the particles and their movement is observed and measured.
Saline solutions are commonly used in electrophoresis as they provide the necessary ions for conducting electricity and also help to maintain a stable pH. Additionally, the concentration and type of salt in the solution can affect the electrophoretic mobility of particles.
Hydrophobic particles are typically less mobile in saline solutions compared to hydrophilic particles. This is because the hydrophobic particles tend to aggregate and form larger clusters, making them less responsive to the electric field.
Electrophoretic mobility in saline solutions has many applications, including protein analysis, DNA sequencing, and drug delivery systems. By understanding the behavior of particles in different conditions, scientists can design more efficient techniques for separating and studying biological molecules and particles.
