3D analysis by electron tomography of PS@AuNPs 200 ppm: (a) PS@Au-Th and (b) PS@Au-PS bright field TEM images at 0° tilt from the tilt series; (c) PS@Au-Th and (d) PS@Au-PS representation of transversal sum of cross-sectional slices along one direction in the plane of 3D reconstructed volume showing different location of AuNPs within the PS layer. The upper and lower interfaces of the hybrid layer are highlighted by dotted lines. The substrate/film interface is on the bottom side of the cross-sectional views as indicated.
