Impulsive Brillouin microscopy

Optica, 2017
Brillouin scattering has been emerging as a viable tool for microscopy. However, most of the work done has been with the use of spontaneous Brillouin scattering, which has several hindrances to its use. In this work, we propose and demonstrate nonlinear Brillouin scattering as a solution to many of these hindrances.

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 ...

Detecting Mechanical Anisotropy of the Cornea Using Brillouin Microscopy. [PDF]

Transl Vis Sci Technol, 2020
The purpose of this study was to detect the mechanical anisotropy of the cornea using Brillouin microscopy along different perturbation directions.Brillouin frequency shift of both whole globes (n = 10) and cornea punches (n = 10) were measured at different angles to the incident laser, thereby probing corneal longitudinal modulus of elasticity along ...

Brillouin microscopy - a revolutionary tool for mechanobiology?

, 2019
The role and importance of mechanical properties of cells and tissues in cellular function, development as well as disease has widely been acknowledged, however standard techniques currently used to assess them exhibit intrinsic limitations. Recently, a new type of optical elastography, namely Brillouin microscopy, has emerged as a non-destructive ...
