Evaluating Nanomedicines: Obstacles and Advancements.

Continued advancements in nanotechnology are expanding the boundaries of medical research, most notably as drug delivery agents for treatment against cancer. Drug delivery with nanotechnology can offer greater control over the biodistribution of therapeutic agents to improve the therapeutic index. In the last 20 years, a number of nanomedicines have transitioned into the clinic. As nanomedicines evolve, techniques to properly evaluate their safety and efficacy must also evolve. Characterization methods for nano-based materials must be adapted to the demands of nanomedicine developers and regulators. This second edition book provides updated characterization protocols designed to address the clinical potential of nanomedicines during their preclinical development. In this chapter, the characterization challenges of nanoparticles intended for drug delivery will be discussed, along with examples of advancements and improvements in nanomedicine characterization.
