ABSTRACT
Although a variety of nanoparticles are known, appropriate selection is required for the intended application. This is because the physical and chemical properties of nanoparticles vary depending on their size, shape, composition, surface chemistry, colloidal properties and surface functional groups. More importantly, interaction with a biological interface depends on these physical/chemical properties of nanoparticles. This chapter focuses on the design considerations for nanoparticles that are required for their biomedical application. This chapter offers general guidelines about the basic requirements and why such requirements are necessary.
