This book explores the advanced integration of nanotechnology and biomedicine, providing an in-depth analysis of the transformative impact of carbon nanotubes (CNTs) on healthcare. It provides a comprehensive coverage of the distinctive characteristics of CNTs, including their remarkable mechanical strength, electrical conductivity, and large surface area, which make them very suitable for numerous biomedical uses. The book provides an overview of the process of synthesizing and functionalizing CNTs. It then delves into the specific applications of CNTs in drug delivery systems to improve the effectiveness and targeting of therapeutic agents. Additionally, the book explores the use of CNTs in imaging and diagnostics, enhancing techniques such as MRI and fluorescence imaging. The book also discusses the involvement of CNTs in tissue engineering, namely in the fabrication of scaffolds that facilitate cell growth and tissue regeneration. It explores the application of CNTs in biosensors, where their high sensitivity enables early and accurate identification of diseases. Antibacterial characteristics of CNTs are reviewed in order to hinder infections in medical devices and implants. The potential of CNTs in gene therapy to enhance genetic treatments is also explored in the book. It addresses the concerns related to the toxicity, biocompatibility, and regulatory issues of CNTs. It carefully balances the promising potential of CNTs with the practical implications of their usage in the field of biomedicine. This book is indispensable for researchers, doctors, and individuals with an interest in the cutting-edge utilisation of nanotechnology in the field of medicine.
