Abstract: | Dendrimers are a class of nano‐sized synthetic polymers with a well‐defined composition and regularly branched tree‐like structure produced by stepwise growth. The uniform size, globular shape and tunable surface chemistry make dendrimers versatile nanoscaffolds to encapsulate or stabilize various inorganic (metal, metal oxide, semiconductor) nanoparticles. In the past decade, research interest in dendrimer–inorganic nanoparticle hybrids has evolved from the development of interesting properties to the exploitation of advanced and useful functions. In particular, because gold nanoparticles with controlled morphology and optical properties have been demonstrated to be promising and versatile candidates for a diverse field of biomedical applications including sensing, in vitro and in vivo imaging, drug delivery, diagnostics and therapies, dendrimer–gold nanoparticle hybrids with biocompatibility have recently been intensively investigated for promising biomedical applications due to their controllable structures and dimensions, as well as their desirable internal and/or external functionalities. In this review, we discuss the recent progress regarding the development of functional dendrimer–gold nanoparticle hybrids for biomedical applications. The strategies for the fabrication of various structures of dendrimer–gold nanoparticle hybrids will first be summarized, followed by their biomedical applications in drug and gene delivery, photothermal therapy and combined therapies. © 2018 Society of Chemical Industry |
