Plasmonics: Fundamentals and Applications

From molecules to crystal engineering: supramolecular isomerism and polymorphism in network solids.

This critical review will be of interest to the experts in porous solids (including catalysis), but also solid state chemists and physicists. It presents the state-of-the-art on hybrid porous solids, their advantages, their new routes of synthesis, the structural concepts useful for their ‘design’, aiming at reaching very large pores. Their dynamic properties and the possibility of predicting their structure are described. The large tunability of the pore size leads to unprecedented properties and applications. They concern adsorption of species, storage and delivery and the physical properties of the dense phases. (323 references)

Hybrid porous solids: past, present, future

Since the first application of the surface plasmon resonance (SPR) phenomenon for sensing almost two decades ago, this method has made great strides both in terms of instrumentation development and applications. SPR sensor technology has been commercialized and SPR biosensors have become a central tool for characterizing and quantifying biomolecular interactions. This paper attempts to review the major developments in SPR technology. Main application areas are outlined and examples of applications of SPR sensor technology are presented. Future prospects of SPR sensor technology are discussed.

Surface plasmon resonance sensors: review

Optical tweezers use the forces exerted by a strongly focused beam of light to trap and move objects ranging in size from tens of nanometres to tens of micrometres. Since their introduction in 1986, the optical tweezer has become an important tool for research in the fields of biology, physical chemistry and soft condensed matter physics. Recent advances promise to take optical tweezers out of the laboratory and into the mainstream of manufacturing and diagnostics; they may even become consumer products. The next generation of single-beam optical traps offers revolutionary new opportunities for fundamental and applied research.

A revolution in optical manipulation

A numerical method is developed to estimate the spectral slit width of a spectrophotometer which degrades the spectral resolution of the measured data. The slit width is estimated from the measured spectrum in certain conditions. This method is based on homomorphic filtering and utilizes the cepstrum of the average log Fourier spectrum of the section spectra. Computer simulations and experimental examples for infrared absorption spectra of ammonia gas demonstrate the potential of the method for practical applications to the preprocessing of deconvolution. A blind deconvolution method is also examined through the experimental result with an ammonia gas spectrum.

Estimation of spectral slit width and blind deconvolution of spectroscopic data by homomorphic filtering

The computed tomography (CT) technique is implemented in an optical transmission microscope with a laser as a light source. A rotational Pechan prism is used in the illumination optics of the microscope for projecting a thick 3-D sample onto a 2-D array detector in different directions. A minicomputer is employed for 3-D reconstruction from the observed image data. Energy throughput efficiency and signal-to-noise ratio in the developed CT microscope are higher than those of our previously developed CT microscope [

We report on light induced orientation by two-photon isomerization of azobenzenes in films of polymer. The dynamics of isomerization and orientation by one-photon absorption and two-photon absorption (TPA) are similar, and TPA creates a degree of molecular orientation which is comparable to that achieved by single-photon isomerization, in agreement with the theoretical predictions of two-photon isomeric orientation.

In this paper, we propose a method for optically improving the resolving power of the photodiode array Fourier transform spectrometer [

The spatial frequency of the interferogram is modulated by the dispersing element added to the triangular common path interferometer so that the spectral resolution is enhanced in the effective spectral range. Since the modification of the method is only the addition of the dispersing optical element to the original optical setup, the advantages of the simple, stable, and easy optical alignment and the large optical throughput with the photodiode array Fourier transform spectroscopy are maintained. Experimental results demonstrate the resolution enhancement by the proposed method with the emission spectra of a low pressure mercury lamp and a cadmium lamp.
