Synthesis, Characterization and DNA-binding Interactions of Inorganic Nanoparticles

Nanoparticles, with their unique mechanical, electronic, optical and magnetic properties due to small size at nanoscales attracted many scientists from different disciplines of science. In recent years, nano-based materials have found potential applications in electronics, materials as fillers, cosmetics, drug delivery systems, medicine, and so on. Metal based nanoparticles especially nanoparticles of gold and quantum dots have been considered a lot for their potential applications in biomedical area. Of course, with the rise of nanotechnology, has increased the concern over the risks of nanoparticles. The object of this PhD thesis is the study of synthesis, characterization, stability, DNA binding interactions and damage effects to living cells of differently capped nanoparticles of gold and cadmium sulphide that are of current interest in bio-applications.
