Update on Gold Nanoparticles


Book Description

In the last decade, gold nanoparticles have provided a suitable platform for the development of novel and efficient diagnostic and therapeutic tools, which avoid the typical drawbacks of the old systems. They are biocompatible and they can be easily synthesised, encapsulated and functionalised with (bio)molecules. Nanoparticles produced by a wet chemistry synthesis have the geometry, which enables the complete control of their optical and physical properties. It is also possible to influence the targeting and stability/release behaviour by coating the nanoparticle surface. In this Update the reader can find in a single volume the methods used most often for the synthesis and coating of gold nanoparticles (spheres, cages, cubes, rods), the links between optical features and geometries of gold nanoparticles, and the novel applications in nanomedicine of gold nanoparticles determined by their geometry. One of the main objectives of this Update is to provide, a readily comprehensible connection in all the chapters between the geometry of gold nanoparticles and their final applications. Another target of this book is to provide information about efficient processes for the synthesis and the coating of gold nanoparticles, all of which have been directly tested by the author. This Update offers comprehensive information on the whole topic from the synthesis of the gold nanoparticles to their medical applications; this is accompanied by a complete and recent bibliography, in order to give to the readers the opportunity to research further the topics addressed in the book. In this way, students and researchers from academia and industry can have a complete picture of gold nanostructures, physicians and biologists can develop ideas and applications for the new nano-tools, and chemists can have a general guide to the synthesis of gold nanoparticles. This is a state-of-the-art guide for the synthesis and uses of gold nanoparticles.

Nanomedicine


Book Description

The application of nanotechnology to medicine is revolutionizing healthcare. This book focuses on the science and engineering driving this revolution, the fabrication of nanostructures for diagnosis and therapy, advanced imaging at the molecular scale and the application of nanoscale physics to bring novel solutions to the detection and treatment of disease. Particular emphasis is placed on hard nanotechnology (e.g. quantum dots, carbon nanotubes, silica) rather than the soft nanotechnology of molecular chemistry. - Presents an overview the subject for physical scientists and engineers - Specific focus on new technologies that have entered the medical arena - Introduces applications and specific case studies by clinical researchers




Nanomedicine


Book Description

The physical mechanisms of action involved when heavy atoms are embedded in biological systems subject to ionising radiation are described with a particular view to providing models for the use of (gold) nanoparticles as targeted agents intended to improve both diagnostic imaging and radiotherapy. Fundamental interactions between ionising radiation and matter are reviewed and then invoked to describe the specific processes arising when nanoparticles containing heavy atoms, and particularly gold nanoparticles, are irradiated in biological systems. Shortcomings in simple macroscopic models of dose distribution are discussed, with the concept of nanodosimetry being used to account for the large effects observed. Finally, some open questions and future research directions are reviewed.
