Monolayer protected gold nanoclusters are of considerable practical interest due to their applications in drug delivery and catalysis. Water-soluble, magic number gold nanoclusters can be generated using para-mercaptobenzoic acid as a capping agent, allowing for improved catalytic activities over larger, citrate stabilized nanoparticles. As a means to generate multiple differentially sized, ultra-small nanoclusters, we have investigated the role of various ionic compounds in controlling the size of para-mercaptobenzoic acid protected gold clusters. Additionally, we have investigated the catalytic activity of these clusters using a model reduction of 4-nitrophenol.<br/>
