1D Nanochain formation: The binding ability of a polyamine molecular linker (L)2− bearing different functional groups, which favors the self-assembling of silver (AgNPs) and gold nanoparticles (AuNPs) into 1D nanochains in aqueous solution was explored. UV/Vis spectrophotometry and TEM were used to determine time-dependent structural changes associated with these 1D structure formations. Sensing of Hg2+ using AgNPs@(L)2− and AuNPs@(L)2− assemblies was also carried out in aqueous solution.
