Abstract:

Colloidal Nanoparticles have received renewed interests recently from the viewpoint of nanoscale science and technology. Using chemical assembling techniques, one can fabricate well-organized 2D nanoparticle arrays on solid substrates and use it as the Coulomb island for room temperature single electron tunneling^[1], as nanoelectrode for electrochemistry studies^[2], as active substrate for surface enhanced Raman scattering (SERS)^[3,4],as lithographic mask for fabrication of nanostructures^[5] and etc.
