The toolkit of nanomaterials covered in this new book, which ranges from magnetic nanoparticles to quantum dots, offers up new possibilities for the preservation and visualization of latent prints and turns forensic science into an area where the unseen is made strikingly visible. This volume acts as a thorough guide through experimental procedures, theoretical underpinnings, and practical uses of nanoparticle-based fingerprinting. Additionally, it examines the potential challenges, future directions, and ethical considerations associated with the adoption of nanoparticle-based fingerprinting methods. The volume investigates fingerprinting techniques that involve titanium dioxide nanoparticles, fluorescent nanoparticles, gold and silver nanoparticles, green synthesis of nanoparticles, iron oxide nanoparticles, carbon dots (CDs) and cadmium selenide (CdSe) nanoparticles, and more. The multidisciplinary approach taken by this book fosters a comprehensive knowledge of this cutting-edge topic by reflecting the joint work of specialists from chemistry, forensic science, and nanoscience. Contributions from leading experts in the fields of nanotechnology and forensic science enrich this volume with diverse perspectives and practical insights. Whether you are a seasoned forensic professional, a researcher in materials science, or a student exploring the intersections of nanotechnology and criminalistics, this book aims to serve as a definitive resource on the transformative role of nanoparticles in advancing fingerprint analysis.
