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.

Publisher Summary This chapter focuses on the oscillatory catalytic reactions at single-crystal surfaces. Among oscillating chemical systems, catalytic reactions at well-defined single-crystal surfaces under low-pressure conditions are conceptually particularly attractive for the following reasons: The reacting medium is strictly two-dimensional and uniform on the mezoscopic length scale, which is relevant for spatial pattern formation. In addition, the low partial pressures cause only minor heat production by the reaction, so that usually isothermal conditions can be kept to within a very good approximation. By combining kinetic measurements with surface-sensitive techniques, it became possible to explore the elementary steps underlying the complex temporal and spatial effects in fair detail, which information, in turn, then could be used for theoretical modeling. For the systems described in the chapter, the following mechanisms is found to determine the occurrence of isothermal kinetic oscillations: (1) adsorbate driven structural transformation, (2) formation and depletion of a subsurface oxygen species, and (3) autocatalytic surface reaction.
