Controlling nanoparticle aggregation is an area of intense investigation. To date, many strategies make use of sophisticated linkers, such as DNA or long polymers. Here we demonstrate the preparation of gold nanoparticle aggregates using simple small molecule cross linkers. The aggregates can be prepared from a range of starting particle sizes and are formed with remarkably low polydispersity. For any given starting building block particle size, the resulting nanoaggregate size can be tuned. The nanoaggregates are readily surface functionalized. These nanoaggregates have unusual plasmonic properties and remarkably low cell uptake.<br/>
