摘要: In this thesis, a generic method was developed for surface modification of nanoparticles (NP) with silica shell using Stober method. Nanoparticles synthesized from nonhydrolytic solvents such as various ethers were first activated silane-based poly(ethylene glycol) (PEG). Because the amphiphilicity PEG moiety, these could be easily transferred hydrophobic to hydrophilic solutions including different biological buffers. After ligand exchange PEG, deposition happen on ethanol and water solvents, ammonium hydroxide catalyst tetraethyl orthosilicate (TEOS) precursor. This has been successfully used iron oxide, silver Pt@iron oxide which oleic acid and/or oleylamine capping agents. Hollow MPEG-sil-SiO2 made NP@MPEG-sil-SiO2 core-shell nanostructures by removing metal or cores acid. Both hollow in drug delivery study penicillin inhibition Streptococcus. mutans. The zones show that have larger loading capacity than ones. A new formation Pt@Fe2O3 yolk-shell Pt@Fe nanoparticles. Under electron beam TEM oxidation shells occurred resulted structures because Kirkandall effect. provided enough energy Pt hop, split move convective motion. demonstrates an approach
