Interactions of Nanomaterials in Biological Systems: Their Characteristics Influencing Interaction

Nanotechnology is an interdisciplinary discipline that deals with issues at the nanoscale level and is being developed for a wide range of applications. One of these appealing and demanding applications is nanomedicine, which focuses on the use of nanomaterials in medical applications such as drug delivery. The use of nanotechnology in personalized medicine offers a once-in-a-lifetime potential to enhance the treatment of a wide range of ailments. Because of their design flexibility, tiny size, high surface-to-volume ratio, and simplicity of surface modification with multivalent ligands to boost avidity for target molecules, nanomaterials have significant benefits as therapeutic and diagnostic tools. Nanomaterials may be tailored to interact with specific biological components, allowing them to benefit from personalized medical insights. A thorough understanding of how nanomaterials interact with biological systems is required to tune these interactions. A thorough knowledge of such interactions can lead to the development of bio-compatible nanomaterials with controlled surface properties in a biological context. The primary goal of this chapter is to outline current information on nanomaterial types in use which include noble metal nanoparticles, polymeric nanostructures, and carbon-based nanomaterials, nanomaterial endocytosis, factors influencing nanoparticle interactions, and their consequences for cellular absorption.
