Carbon nanotubes (CNTs) have 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 CNTs. The primary objective of the editors and authors is to exhaustively cover the fundamentals of carbon nanomaterials, carbon nanotubes, functionalization and chemistries involved, drug delivery aspects, and applications along with their regulatory aspects.
