abstract Bioapplications of gold nanoparticles (Au NPs) have received significant attention due to their sensitive optical characteristics which depend on particle size and shape, state of aggregation and to surrounding (bio)chemical environment. In this review, we present an overview of several methods to synthesise stable colloidal Au NPs with focus on the use of the electrostatic assembly method of polyelectrolytes (PE) to functionalise Au NPs. This versatile method allows adjusting the thickness, chemical functions and the surface charge of the shells surrounding the Au NPs, thus the relevance of these features for the bioapplications of Au NPs involving surface-mediated processes is discussed. Moreover, because the PE used can be functionalised with organic fluorophores, drugs or antibodies yielding multifunctional nanocomposites useful for those applications, this review also provides an overview of the electrostatic assembly of functionalised PE onto Au NPs and their bioapplications.
