Abstract

The biocompatibility, including aspects such as biodistribution, clearance, and immunotoxicity, of a nanoparticle depends upon its physicochemical properties. Characteristics such as size, charge, and hydrophobicity are well-known parameters influencing the biological compatibility of in vivo administered nanoparticles. Measurement and evaluation of these and other parameters, however, are not always straightforward. This chapter describes six critical areas for nanoparticle characterization, especially as pertaining to polymer nanoparticles intended as therapeutics: starting polymer characterization, nanoparticle size, nanoparticle surface properties, drug loading and release, nanoparticle stability, and batch-to-batch reproducibility. The challenges and limitations of the most common techniques used in assessment of these parameters are described.
