Antibacterial properties of spinel ferrite nanoparticles

This book chapter is organized into four major parts. Firstly, it will cover an introduction of using spinel ferrite nanoparticles in biomedical applications, including the antibacterial properties. The second part will provide an overview of the structure and magnetism of spinel ferrites. The third part will focus on the preparation of cobalt ferrite and transition metal substituted cobalt ferrite nanoparticles by sol-gel methods. The last part will highlight the influence of transition metal concentration on the physical properties, and antibacterial property of transition metal substituted cobalt ferrite nanoparticles. A discussion on the mechanisms for the antibacterial properties will be presented
