“…However, some substitutions can significantly redshift its absorption spectrum. Therefore, various naphthalene-based fluorophores, such as 1-anilino-8-naphthalenesulfonate (ANS), , 6-propionyl 2-(N,N-dimethyl)aminonaphthalene (PRODAN), − 6-lauroyl-2-(dimethylamino)-naphtalene (LAURDAN), and 6-dimethylamino-2-acylnaphthalene (DAN), − have been developed, some of which have been further developed into the format of fluorescent UAAs for biological studies. For example, an alanine derivative of DAN, 6-(2-dimethylaminonaphthoyl)alanine (Aladan), was synthesized by Cohen and co-workers and by Imperiali and co-workers .…”

Due to advances in methods for site-specific incorporation of unnatural amino acids (UAAs) into proteins, a large number of UAAs with tailored chemical and/or physical properties have been developed and used in a wide array of biological applications. In particular, UAAs with specific spectroscopic characteristics can be used as external reporters to produce additional signals, hence increasing the information content obtainable in protein spectroscopic and/or imaging measurements. In this Review, we summarize the progress in the past two decades in the development of such UAAs and their applications in biological spectroscopy and microscopy, with a focus on UAAs that can be used as site-specific vibrational, fluorescence, electron paramagnetic resonance (EPR), or nuclear magnetic resonance (NMR) probes. Wherever applicable, we also discuss future directions.

An optical-mechanical model has been developed to describe the transmittance, polarization and small-angle distribution of light scattered by an uniaxially-stretched polymer film containing the elongated ellipsoidal droplets of nematic liquid crystal. It is based on the approximations of Foldy-Twersky, anomalous diffraction, and single scattering. The spectral dependences of transmittances and polarizing abilities of the polymer dispersed liquid crystal films have been analyzed as well as the small-angle intensity distribution and the polarization degree of scattered light depending on the film thicknesses, refractive index of polymer matrix, sizes of droplets, their anisometry parameters, concentration, polydispersity, and optical axes orientation. The optical characteristics of films with homogeneous and inhomogeneous interfacial anchoring at the surface of liquid crystal droplets have been considered. The transmittance and polarizing ability of the films have been studied as functions of the angular aperture of the system recording scattered light. Highlights: Polarization degree >0.97 of passed light is possible in spectral range 0.45-0.7 m Polarization degree >0.95 and transmittance 0.5 are achieved at angular aperture <3º Stretched films with monodomain and bipolar structures are effective light polarizers
