ABSTRACT
The synthesis of nanoparticles has received a great deal of interest and attention because of their potential biomedical applications, which in turn are affected by the kind of surface modification. A variety of nanomaterials, including magnetite superparamagnetic iron oxide nanoparticles and nobel metal nanoparticles such as gold, have been the focus of many research fields particularly in medicine and biomedical engineering, which has shown a promising advancement. The resultant nanocomposites have much applicable potential, such as gen vector, catalysis, resonance imaging agents, and nanocapsules. Medical imaging is very important for medical diagnosis and research and each of imaging modality has its own strength and weakness. There is much interest in the development of fibre delivering system for tissue ablation, imaging, spectroscopy, thermometry, and similar fields using infrared and ultraviolet lasers. The chapter discusses the effects of gold nanoparticle concentration inside a tissue phantom using a combined system of photoacoustic and optical beam deflection and their applications particularly to photoacoustic imaging.
