Cellular mechanical properties in response to environmental viscosity imaged by Brillouin Microscopy [PDF]

Communications Biology
An increasing body of research in biomechanics has revealed that the stiffness of the surrounding environment influences cells fate and function. In this context, a recent study showed that cells exposed to highly viscous fluids migrated and spread ...

Progressive alteration of murine bladder elasticity in actinic cystitis detected by Brillouin microscopy [PDF]

Scientific Reports
Bladder mechanical properties are critical for organ function and tissue homeostasis. Therefore, alterations of tissue mechanics are linked to disease onset and progression. This study aims to characterize the tissue elasticity of the murine bladder wall

Frequency comb enhanced Brillouin microscopy

Optics Express, 2020
Brillouin light scattering (BLS) microscopy is a well established and powerful technique to study acoustic and magnetic excitations in the frequency domain with sub-micron spatial resolution. Many other spectroscopic techniques have benefited from the introduction of femtosecond laser sources to optically pump and stimulate the sample under ...

Effect of quantum confinement on the dielectric function of PbSe [PDF]

, 2004
Monolayers of lead selenide nanocrystals of a few nanometers in height have been made by electrodeposition on a Au(111) substrate. These layers show a thickness-dependent dielectric function, which was determined using spectroscopic ellipsometry.
