Understanding the interaction between metal nanostructures and common metal ions is essential for biomedical applications of metal nanostructures including imaging and therapy. A systemic study of the interaction of citratecapped hollow gold nanospheres (HGNs), a unique metal nanostructure that has demonstrated high efficiency for photothermal ablation (PTA) therapy of cancer cells, with common metal ions: Na+, Ca2+, Mg2+, Cu2+, Zn2+, and Al3+ was carried out with the goal to determine how these metal ions may affect the properties and thereby performance of HGNs in biomedical applications. Specifically, the study focuses on the issue of metal ion induced aggregation of HGNs since aggregation can strongly influence the optical and photothermal properties of the HGNs. The level of HGNs aggregation caused by interaction with metal ions was found to depend on.. View More»
