Aligned Au nanoparticles on glass
3D rendering of an AFM topographical image, 450nm scan of 12nm Au nanoparticles (NP)
on a wafer-grade polished glass substrate. The NPs were initially aligned using insulin fibers as
an adherent sacrificial biotemplate. Fibers were subsequently removed by exposure to a
low-pressure plasma, leaving the Au NPs in their template positions. Imaged with the MFP-3D AFM.
