Microelectrophoresis

Microelectrophoresis is a method of studying electrophoresis of various dispersed particles using optical microscopy. This method provides image of moving particles, which is its unique advantage. e.g. observation of RBCs, neutrophiles and bacteria. This type of electrophoresis is carried out in a closed medium with critical observations by focusing and adjusting the lens of microscope. 
The second complexity comes from necessity of diluting sample, if it was initially concentrated. Concentration must be sufficiently low for observing individual particles. 
Measurement in the low polar fluids present additional problems. These systems have low electrical conductivity and low dielectric permittivity. Electrophoretic mobility is low and this requires high electric field, by factor 10 and higher.
