  1. Core-shell nanoparticle Fig.2.24 SNOM image of SiHa cells incubated with gold ions showing the formation of nanoparticles in the cytoplasm (From the author’s work).

  2. Metal-metal oxide nanoparticle Fig.9.1 Transmission electron micrographs of silica coated gold nanoparticles. The shell thicknesses are (a) 10 nm, (b) 23 nm, (c) 58 nm and (d) 83 nm.

  3. Metal-Metal oxide nanoparticle Fig.9.2 TEM image of ZrO2 coated Ag nanoparticles

  4. Metal-metal nanoparticle Fig.9.3 TEM image of Pt-maghemite core-shell nanoparticles having different shell thickness made with different shell-forming precursors. The shell thicknesses are 3.5 nm and 5.4 nm, respectively (left to right). Fig.9.6 TEM images of Au nanoparticles (left) coated with Pt (right) in the ratio of 1:2.

  5. Fig.9.9 TEM of LbL assembled polystyrene-capped Au nanoparticles Fig.9.7 TEM of polypyrrole coated SiO2 core-shell nanoparticles

  6. Fig.9.14 The absorption spectra of Au@SiO2 colloids as a function of solvent refractive index (top figures) and Ag@TiO2 (bottom (A)) and Ag@ZrO2 (bottom (B)) as a function of increasing core dimension, a-d (A) and increasing shell thickness, a-d (B).
