Figure 3

(a) Scheme of the monomer mediated in situ growth strategy for the core-shell Au@pMMA nanohybrids synthesis; (b) S-TEM images of nanohybrids obtained in different H2O/EtOH concentration ratio: (b-i) G6 and (b-ii) G7, both at high and low magnification. SEM image of G6 is reproduced in left-top of (b-i); (c) Size diameter by intensity distribution and (d) UV-Vis absorption of the nanostructures. Inset: color variation of the Au@pMMA nanohybrid solutions with the shell-morphology changes.
