This lab manual guides chemists through demonstrations of synergistic effects between polyelectrolytes
and nanoparticles. After a short introduction into the field of polyelectrolytes and polyelectrolyte
characterization, the role of polyelectrolytes in the process of nanoparticle formation is discussed in more
detail. However, polyelectrolytes can directly influence the growing of nanoparticles and also can stabilize
the nanoparticles formed.
Therefore, the nanoparticle formation in polyelectrolyte-modified template phases,
e.g. microemulsions, is of growing interest. Finally, methods for characterization of the polyelectrolyte-modified
nanoparticles are explained. The adsorption of polyelectrolytes can be detected by measuring the zeta potential
at the nanoparticle surface by means of electrophoretic light scattering, acoustophoresis or streaming potential
measurements. It is also shown that the particle size and particle size distribution can be determined by using
dynamic light scattering in combination with electron microscopy. Moreover, all methods and
preparation techniques are discussed in sufficient detail to give readers deeper insight into
the methodical background.
Of interest to scientists, graduate students, practitioners in industry and at universities in the field of
Polymer and Materials Sciences, Nanoscience, Colloid and Interface Science, Pharmaceutical Technology,
as well as Peptides and Proteins
