The use of periodically structured illumination coupled with spatial Fourier-transform fluorescence recovery after photobleaching (FT-FRAP) was shown to support diffusivity mapping within segmented domains arbitrary shape. Periodic "comb-bleach" patterning the excitation beam during encoded maps diffusion onto harmonic peaks in Fourier transform. Diffusion manifests as a simple exponential decay given harmonic, improving signal noise ratio and simplifying mathematical analysis. Image...
Fourier transform-fluorescence recovery after photobleaching (FT-FRAP) using a diffractive optical element (DOE) is shown to support distance-dependent diffusion analysis in biologically relevant media. Integration of DOEs enables patterning dot array for parallel acquisition point-bleach FRAP measurements at multiple locations across the field view. In homogeneous media, spatial harmonics analyzed transform domain yield curves evaluated over specific well-defined distances. Relative...
The gas-polymer and liquid-polymer interfacial reactions of photosensitive polyimide can annihilate photo-reactive carbon-carbon double bonds, which remain after photo-alignment process. annihilation processes dramatically affect voltage holding ratio reorientation photo-active functional groups. Photochemical dimerizations were identified using UV-visible FT-IR spectroscopy. Polyimide films containing cinnamate groups irradiated by linear polarized ultra violet (LPUV) light. Schadt et al....
Multiphoton-excited fluorescence recovery while photobleaching (FRWP) is demonstrated as a method for quantitative measurements of rapid molecular diffusion over microsecond to millisecond timescales. Diffusion are crucial in assessing mobility cell biology, materials science, and pharmacology. Optical microscopy techniques enable non-invasive analysis but can be challenging systems with coefficients exceeding ∼100 μm2/s. As an example, after (FRAP) operates on the implicit assumption...
Analytical theory is proposed predicting remarkably large and fully electric-dipole-allowed circular dichroism (CD) in electronic ultraviolet–visible (UV–vis) absorbance spectroscopy of uniaxial surface assemblies. Partial depolarization the transmitted beam provides a pathway for surface-specific chiral-specific dissymmetry parameters that are orders magnitude greater than those from analogous measurements isotropic systems. Predictions model generated using ab initio quantum chemical...
