Show moreInorganic nanoparticles are attractive materials due to their unique properties and prominent role in the fields of material science, nanotechnology and nanomedicine. Modern therapies aim to deliver drugs specifically to defective cells and mesoporous silica nanoparticles (MSNs) are considered to be promising candidates for this goal. In this thesis the synthesis, characterization and bio-applications of silica nanoparticles will be discussed. Moreover, the potential application of mesoporous silica nanoparticles as drug delivery systems will be discussed using two animal models: the Xenopus laevis and the Danio rerio. Show less
