<br/><br/> The success of synthesizing monolayer protected clusters (MPCs) in the condensed phase has allowed scientists to probe their optical properties directly. Au MPCs have become the “gold” standard in nanocluster science due to the use of very rigorous chemical and structural characterization techniques to probe the properties of the MPCs. The use of ultrafast laser spectroscopy to investigate the dynamics of MPCs in solution provides the benefit of directly studying the mechanisms of the dynamics as well as their non-linear optical properties. Based on the use of nonlinear and time-resolved spectroscopic techniques it is clear that monolayer protected metal clusters have unique physical and optical properties which are different than their larger metal particle counterparts. In this presentation the basic optical properties of small gold, silver, and mixed clusters will be presented. Both linear and nonlinear optical measurements as well as steady state and time-resolved investigations of these metal clusters will be presented. Further work suggesting that the basic scientific information regarding MPCs can be combined with innovative nanotechnology to inspire creative applications in imaging, diagnostics, and therapeutics.
