Abstract:
Fluorescence polarization is related to the dipole orientation of chromophores, making fluorescence polarization microscopy possible to reveal structures and functions of tagged cellular organelles and biological macromolecules. Several recent super resolution techniques have been applied to fluorescence polarization microscopy, achieving dipole measurement at nanoscale. In this review, we summarize both diffraction limited and super resolution fluorescence polarization microscopy techniques, as well as their applications in biological imaging.

Abstract:
Abstract Fluorescence polarization microscopy, which can visualize both position and orientation of fluorescent molecules, is useful for analyzing architectural dynamics of proteins in vivo, especially that of cytoskeletal proteins such as actin. Fluorescent phalloidin conjugates and SiR-actin can be used as F-actin orientation probes for fluorescence polarization microscopy, but a lack of appropriate methods for their introduction to living specimens especially to tissues, embryos, and whole animals hampers their applications to image the orientation of F-actin. To solve this problem, we have

The demonstration of an electrically pumped organic laser remains a major issue of organic optoelectronics for several decades. This goal requires an improved device configuration so as to reduce losses which are intrinsically higher under electrical excitation compared to optical pumping. Moreover a systematic investigation of the material properties is still missing and should lead to a reliable estimate of the lasing threshold under optical pumping, and then to a lower limit for electrical pumping.

Abstract:
This chapter reviews the use of fluorescent methods in the study of single molecules, how the foundations of fluorescence are rooted in Einstein’s description of absorption and emission (spontaneous and stimulated), and their quantum-mechanical explanation in terms of transitions between quantized energy levels, as represented in Jablonski diagrams. It describes the non-radiative channels which compete with fluorescent emission, decrease its efficiency, and ultimately destroy the fluorescent molecule. Fluorescence Polarization Spectroscopy, FRET, and FCS are briefly presented. Without reviewing the various available fluorophores, it describes the various illumination methods used to study them, sketching super-resolution methods (STED, STORM, PALM) that have recently allowed fluorophores to be resolved to a few tens of nanometres. Finally, it describes the considerations (bandwidth, signal to noise, signal to background) used in choosing a single-molecule fluorescence detector, and the extraction of the diffusion constant of a fluorophore from the finite time, noisy traces of its positions.

Abstract:
Optical spectroscopy, Spectrophotometry and fluorimetry can be used to monitor processes occurring in living cells provided that suitable chromophores are present which ‘report’ on the events in which they participate. The advantages of optical techniques are manifold. Firstly they can be fast—with appropriate apparatus events in the pico- and nano-second domains can be studied by fluorescence spectroscopy. Secondly they are continuous—instant feedback from the experimental system can guide the most complex of experimental protocols, and allow the experimenter to adjust system parameters as necessary. Thirdly they are convenient, and most laboratories have access to equipment that can provide quantitative analysis of optical signals; examples include conventional spectrophotometers/fluorimeters, dedicated instruments (e.g. for fluorescence lifetime and polarization measurements), cameras, microscopes and plate readers. Significantly detectors from one apparatus can often be used on others to open up new experimental protocols. Fortunately the principles underlying the use of such a diverse array of optical devices are straightforward and universal—they apply just as much to laboratory ‘work-horse’ instruments as they do to the most specialized, laser-illuminated fluorescence microscope. The availability of fast laboratory computers with large storage capacities means that most modern spectrometers are microprocessor controlled and digitization of signals opens up the full range of possibilities of data accumulation, storage, analysis and interpretation. The main problem with optical measurements is not the acquisition but rather the interpretation of the data obtained. Straightforward analysis of the results depends on the clarity of the experimental design and the appropriate choice of chromophore. This chapter describes some of the problems that can be addressed by spectroscopic techniques and attempts to give guidance on good experimental design. Optical spectroscopy requires either spectrophotometers, to measure absorbance, fluorimeters, to measure fluorescence, or microscopes, which can measure fluorescence or absorbance of single cells or small groups of cells. Fluorimeters and spectrophotometers usually require solutions or suspensions of material in conventional cuvettes; microscopes provide two-dimensional images from smears, slices or surfaces. Other devices that record signals resolved in two-dimensions include gel scanners and microplate readers.

Abstract:
The general approach used in choosing a polymer suitable for a particular application is: . . . Polymerization ↔ Structure ↔ Properties ↔ Application . . . For example, if one wants a polymer for fire-resistant fabrics, then a polymer with good high-temperature properties is required, which implies aromatic structures, which suggest condensation polymerizations. More relevant here, however, would be that a polymer remains elastomeric at low temperatures. This requirement evokes a polymer with high flexibility (low glass transition temperature), which indicates use of the polymerization techniques used with the polysiloxanes. An example of a relevant optical property is the birefringence of a deformed polymer network. This strain-induced birefringence can be used to characterize segmental orientation, and both Gaussian and non-Gaussian elasticity. Infrared dichroism has also been helpful in this regard. In the case of the crystallizable polysiloxane elastomers, orientation is of critical importance with regard to strain-induced crystallization and the tremendous reinforcement it provides. Segmental orientation has also been characterized by fluorescence polarization, deuterium nuclear magnetic resonance (NMR), and polarized infrared spectroscopy. Infrared spectroscopy has been used to characterize the structures of silica-filled polydimethylsiloxane (PDMS). Other optical and spectroscopic techniques are also important, including positron annihilation lifetime spectroscopy, spectroscopic ellipsometry, confocal Raman spectroscopy, and photoluminescence spectroscopy. Surface-enhanced Raman spectroscopy has been made tunable using gold nanorods and strain control on elastomeric PDMS substrates. A great deal of information is now being obtained on filler dispersion and other aspects of elastomer structure and morphology through the use of scanning probe microscopy, which consists of several approaches. One approach is that of scanning tunneling microscopy (STM), in which an extremely sharp metal tip on a cantilever is passed along the surface while measuring the electric current flowing through quantum mechanical tunneling. Monitoring the current then permits maintaining the probe at a fixed height above the surface. Display of probe height as a function of surface coordinates then gives the desired topographic map. One limitation of this approach is the requirement that the sample be electrically conductive. Atomic force microscopy (AFM), on the other hand, does not require a conducting Surface.
