Plasmonics: Fundamentals and Applications

The surface science of titanium dioxide

Self-assembly is the autonomous organization of components into patterns or structures without human intervention. Self-assembling processes are common throughout nature and technology. They involve components from the molecular (crystals) to the planetary (weather systems) scale and many different kinds of interactions. The concept of self-assembly is used increasingly in many disciplines, with a different flavor and emphasis in each.

Self-assembly at all scales.

Recent developments have greatly improved the sensitivity of optical sensors based on metal nanoparticle arrays and single nanoparticles. We introduce the localized surface plasmon resonance (LSPR) sensor and describe how its exquisite sensitivity to size, shape and environment can be harnessed to detect molecular binding events and changes in molecular conformation. We then describe recent progress in three areas representing the most significant challenges: pushing sensitivity towards the single-molecule detection limit, combining LSPR with complementary molecular identification techniques such as surface-enhanced Raman spectroscopy, and practical development of sensors and instrumentation for routine use and high-throughput detection. This review highlights several exceptionally promising research directions and discusses how diverse applications of plasmonic nanoparticles can be integrated in the near future.

Biosensing with plasmonic nanosensors

I was fortunate to start my career in physical chemistry at a time when the development of the ultrahigh vacuum technique and of novel physical methods enabled the study of processes on well-defined surfaces at an atomic scale. These investigations included the mechanisms of heterogeneously catalyzed reactions, such as CO oxidation and ammonia synthesis, and phenomena of spatio-temporal self-organization, as described by the concepts of nonlinear dynamics.

Na-Y zeolite was cation exchanged with Ru and tested in ammonia synthesis at atmospheric pressure. Activities up to ∼10% of the commercial iron catalyst scaled by the active surface area were observed. Characterization of the zeolites with XPS was complemented with reference thermal desorption spectroscopy data on a polycrystalline Ru metal surface. The catalysts showed high thermal stability in in situ reduction-oxidation cycles

Dynamics of Surface Reactions

The Belousov–Zhabotinsky (BZ) reaction is used extensively as a model chemical system in the studies of self-organization phenomena. Thus, it plays a role similar to that of Drosophila, or the fruit fly, in molecular genetics. It has not been the first oscillatory reaction discovered, and its full kinetic mechanism is quite complex and still not completely understood. Nonetheless, it can be easily prepared and run; it is also easy to control. The oscillation periods are in the range of tens of seconds and the wavelengths of spatial patterns are in the millimeter range, allowing for observations by the non-aided eye.
