Carbon nanotubes (CNTs) has emerged as novel carbon based nanomaterials with unique physicochemical properties for pharmaceutical and biomedical applications. This book provides the fundamental concept, basic physicochemical properties, functionalization, method of synthesis, applications and regulatory considerations of carbon nanotubes (CNTs). The prime objective of the Editors and Authors would be to exhaustively cover the basic fundamentals of carbon nanomaterials, carbon nanotubes, functionalization and chemistries involved, drug delivery aspects and applications with their regulatory aspects.
