This volume includes four chapters that detail advances in nanotechnology. Chapter 1 highlights the achievements made in point-of-care testing systems for pathogen detection. Chapter 2 discusses processes in lyophilization and how it plays an important role in the stability of marketed evolutions in nanotechnology and nanomedicine (nanopharmaceuticals). Chapter 3 explores the latest strategies, advances, and real-world applications of smart nanocarriers in antifungal therapy. Chapter 4 aims to address the long-term safety and effectiveness of innovative nano-adjuvants in delivering antigens and immunomodulators to customize the immune response toward specific cellular components.
