Applications of zeta potential measurement in biotechnology

摘要

On of the emerging analytical technologies in biotechnology industry is zeta potential measurement. Zeta potential measurement not only can provide surface information on colloidal biomaterials but more importantly can be used in bioprocess control and products quality control. The principle of the most advanced and popular zeta potential measurement technique, electrophoretic light scattering, will be briefly introduced; studies of colloid surface morphology from two model systems and a few applications in using zeta potential measurement to study and monitor biomaterials are described.
