Protein charge positive or negative
WebbA large positive or negative value of zeta potential of nanocrystals indicate good physical stability of nanosuspensions due to electrostatic repulsion of individual particles. A zeta potential value other than −30 mV to +30 mV is generally considered to have sufficient repulsive force to attain better physical colloidal stability.
