Drug-delivery, Antimicrobial, Anticancerous Applications of Green Synthesized Nanomaterials

Nanomaterials have been extensively used in various applications owing to the unique physicochemical properties exhibited by these materials in the size of 1–100 nm. Nanomaterials are extensively used in biomedical applications owing to their easy surface functionalization for targeted therapeutics, integration of multiple modalities within a single nanoplatform, size, shapedependent tuning of physicochemical properties, etc. Despite the technical advancements in the development of nanomaterials, they are still limited in their clinical use due to their toxic side effects. Green synthesis of nanomaterials, typically using plant-based products/extracts or microbial extracts, has emerged as an affordable, simple yet safe alternative for the synthesis and development of several nanosystems that can be used for biomedical applications. Hence, this chapter focuses on the methods and use of green synthesis of various metallic nanosystems and their subsequent use in various biomedical applications such as drug delivery for antimicrobial and anticancer activity in detail using the supporting literature.
