The project comprises synthesis and characterization of different morphologies of gold and silver nanoparticles.
Those nanoparticles show a high chemical affinity toward specific chemical functionalities namely; thiol and amine.
Theses characteristic chemical features of those nanoparticles allow them to self-assemble onto amino functionalized silicon substrate. Further functionalization of those nanoparticles with specific linker molecule through thiol moiety from one side and double bond from the other side to be crosslinked with polyethylene glycol prepolymer under UV-light, allow their facial transference from silicon surface to the surface of PEG polymer.
The work generated a number of nano- and micro- patterned gold nanoparticles for controlled and selective immobilization of biofunctional molecules.
