Figure 1From: In Situ Generation of Two-Dimensional Au–Pt Core–Shell Nanoparticle Assemblies a 2μm × 2μm and b 5μm × 5μm tapping mode AFM height image of in situ generated bimetallic Au–Pt NPs (Au:Pt mole ratio = 1:1) on TSPEI modified surface. c 2μm × 2μm AFM height image of monometallic Au NPs generated on TSPEI modified surface. Inset of (a) and (c) show the respective histogram of the Au–Pt and Au nanoparticle height distribution with a fit (solid line) using Gaussian distribution function after analyzing a number of AFM images. Respective mean height and standard deviation are also shown. d Change in static water contact angle at different steps of Au–Pt NP formationBack to article page
