TL;DR: In this paper, the reflection of light from an air-water interface is enhanced by dye containing monolayers in the spectral region of the dye absorption, and the intensity of reflected light depends linearly on the density of chromophores in the mixed monolayer.
Abstract: The reflection of light from an air–water interface is enhanced by dye containing monolayers in the spectral region of the dye absorption. The intensity of the reflected light depends linearly on the density of chromophores in the mixed monolayer. From the measurement of both absorption and reflection spectra of a dye containing monolayer the damping constant of coherent light scattering can be estimated. The value of the reflection measurement for the investigation of adsorption processes and the control of monolayer organization is demonstrated.

TL;DR: In this article, light scattering off a 2D dipolar array is considered and the lattice constant of the order of the incident wavelength is chosen to shape the emission pattern from an individual quantum emitter into a well-defined, collimated beam.
Abstract: We consider light scattering off a two-dimensional (2D) dipolar array and show how it can be tailored by properly choosing the lattice constant of the order of the incident wavelength. In particular, we demonstrate that such arrays can operate as a nearly perfect mirror for a wide range of incident angles and frequencies, and shape the emission pattern from an individual quantum emitter into a well-defined, collimated beam. These results can be understood in terms of the cooperative resonances of the surface modes supported by the 2D array. Experimental realizations are discussed, using ultracold arrays of trapped atoms and excitons in 2D semiconductor materials, as well as potential applications ranging from atomically thin metasurfaces to single photon nonlinear optics and nanomechanics.

TL;DR: It is shown that the dependence of absorbance on mitochondrial concentration can be linearized, resulting in an intrinsic light scattering parameter which is independent of the concentration and source of mitochondria, and the absorbance osmotic curve is segmentally linear.
