摘要：Gold nanoshells containing a dielectric core inside, typically silica, have aroused significant interest in recent years due to their tunable plasmon resonances. By appropriately adjusting the core-to-shell ratio, the plasmon resonance effect can be tuned from visible to the near-infrared (NIR) 'biological window' region, which enables various potential biomedical applications in cancer diagnosis and photothermal therapy. In addition, characterization results were unsatisfactory because of the irregularity and non-uniformity of the multilayered nanostructure. To verify the theoretical calculation results and pave the way for future applications, a facile yet reliable approach for synthesizing multilayered gold nanoshells with satisfactory uniformity, monodispersity, reproducibility and structural stability is undoubtedly necessary.
