3D analysis by electron tomography of PS@AuNPs 400 ppm: (a) PS@Au-Th and (b) PS@Au-PS bright field TEM image 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 the 3D reconstructed volume showing different locations 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.
