... subject of our on- going investigation. Conclusions In summary, we have reported an elegant method for in situ generation of two-dimensional Au–Pt bimetallic nanoparti- cle assemblies on solid ... for curing of the silane layer. In a subsequent step, [AuCl 4 ] - ion adsorption was done by exposing the surfaces in a 1 9 10 -2 M solution of HAuCl 4 Á3H 2 O for 8 h followed...
