Cancer is one of the leading causes of death in the world and preparation to the light energy harvesting assemblies for efficient light energy conversion to electric energy due to the worldwide increasing energy demand and crisis with remedy of the environment pollution. Searching for efficient method of selective cancer cell killing therapy and efficient light energy conversion to electric energy are extremely active field today. With the great development of nanotechnology, various nanoparticles in different structure, shapes and composites provides good potential for their application in cancer cell killing therapy and photoelectrochemical cell charge separation. The noble metal nanoparticles has drawn much attention on cancer cells because noble metal nanoparticles have size encourage electronic and optical properties, surface plasmon absorption, tunable and enhanced scattering and absorption properties as well as photostability and potential noncytotoxicity. Their strong absorption provides a possibility for them to be a used in photothermal cancer cell killing therapy. The metal nanoparticles on semiconductors and metal ions in semiconductor lattice structure have promoted the interfacial charge separation and tailored the photoresponse in visible light region. This two properties of metalsemiconductors nanophotocatalysts have provide the possibility of photocatalytic cancer cell killing and photoelectrochemical cell charge separation and hydrogen production. In this thesis, we showed with experimental results and discussion that both noble metal (Au) nanoparticles and metal-semiconductor nanophotocatalysts has efficient for cancer cell killing and photoelectrochemical charge separation and also hydrogen production.}, title = {Development, Evaluation and Application of Metal Nanoparticles, Nanophotocatalysts and Nanocomposites}, year = {} }
