Safety Assessment of Nanoprobes

Up to date, a lot of nanoprobes were designed and prepared for tumor imaging and therapy. These nanoprobes have to be evaluated and then are used for clinical application. This chapter summarized a systematic assessment method of the safety of nanoprobes, and existed difficulty and challenge. Nanomaterials still require a lot of research based on the current status of the safety assessment, and this is just the start of a new cross-cutting areas, and need to use research tools and knowledge of nanotechnology, biology, medicine, chemistry and physics and other fields to study, so this is a full opportunities for scientific innovation opportunity of human needs and the forefront of science.
