Dip-pen nanolithography (DPN) in conjunction with wet chemical etching was used to synthesize a new class of open-ended, cylindrical Au−Ag alloy nanostructures on a Si/SiOx surface. Ag nanostructures were prepared by depositing dot MHA features on Ag-coated Si/SiOx, followed by etching with ferri/fe...
