Nanoparticle PreparationChemical Methods• Microemulsions- Microemulsions are similar toimpregnation however the metal salt isdissolved in a emulsion which thenimpregnates the porous supportstructure. This method has resulted ingreater control of particle size.• Photochemistryh t- Photochemistry involves a high wattagelight source in order to excite moleculesand add energy to reactions. Theadditional energy allows for depositionsthat might not normally occur.http://www.fbi.gov/hq/lab/labannual05/page_iiic.jpg• Chemical Vapour Deposition- This method involves the vaporizationof metals followed by the formation andgrowth of nanoparticles under vacuumconditions. This method allows for awide variety of support structures.
Nanoparticle PreparationSurface Capping• Surface capping is an emergingsolution to some of thelimitation of conventionalchemical nanoparticlepreparation.• Surface capping employeespolymeric or molecular cappingagents to increase control overnanoparticle size and surfaceproperties.• Nanoparticles formed are oftenin a shell structure with themetal tl at tththe core and dththepolymers as the outside layer.• By controlling the amount ofcapping agent nanoparticleshape, size and stability can becontrolled.http://www.molecularassembler.com/Papers/PDMM/Slide68.GIF
