by their chemical composition and the method employed in their preparation. The
extrapolation of results of one colloidal system to another is thus difficult.
Lipid nanoparticle preparation is a well-established field of research and many
researchers are attracted to this area of colloidal carriers. A number of questions
such as the interaction of drugs with lipid carriers and the presence of other colloi-
dal systems within the formulations are yet unanswered unambiguously. Both the
introduction of new production procedures and variation of the lipid nanoparticle
composition may affect system properties in unexpected ways. An intensive char-
acterization scheme will be required to investigate the structure and behavior of
complex colloidal carriers. This chapter has summarised the techniques available
for such characterization.
