Nature Reviews Methods PrimersThe field of Brillouin microscopy and imaging was established approximately 20 years ago, thanks to the development of non-scanning high-resolution optical spectrometers. Since then, the field has experienced rapid expansion, incorporating technologies from telecommunications, astrophotonics, multiplexed microscopy, quantum optics and machine learning.

Measuring mechanical anisotropy of the cornea with Brillouin microscopy [PDF]
Nature Communications, 2022 Here, Brillouin optical microscopy noninvasively visualizes microscale anisotropy of the porcine cornea owing to its lamellar fiber structure and quantifies the longitudinal moduli of the bulk tissue.

Current Opinion in Ophthalmology, 2018 Assessment of corneal biomechanics has been an unmet clinical need in ophthalmology for many years. Many researchers and clinicians have identified corneal biomechanics as source of variability in refractive procedures and one of the main factors in keratoconus. However, it has been difficult to accurately characterize corneal biomechanics in patients.

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.

Characterization of retinal biomechanical properties using Brillouin microscopy [PDF]
Journal of Biomedical Optics, 2020 The retina is critical for vision, and several diseases may alter its biomechanical properties. However, assessing the biomechanical properties of the retina nondestructively is a challenge due to its fragile nature and location within the eye globe.

A 3D Brillouin microscopy dataset of the in-vivo zebrafish eye [PDF]
Data in Brief, 2020 In this work we present three-dimensional (3D) measurements of Brillouin scattering spectra of the in-vivo zebrafish larvae eye. This dataset was obtained by Brillouin microscopy, an emerging all-optical and non-contact technique that gives access to ...

Assessing
Journal of BiophotonicsABSTRACTKeratoconus and other corneal ectatic disorders involve the degradation of collagen fibers, which compromises the corneal biomechanical properties. Ultraviolet‐A (UVA) crosslinking has emerged as the primary treatment to slow down collagen degradation.

Time-lapse mechanical imaging of neural tube closure in live embryo using Brillouin microscopy [PDF]
Scientific Reports, 2023 Neural tube closure (NTC) is a complex process of embryonic development involving molecular, cellular, and biomechanical mechanisms. While the genetic factors and biochemical signaling have been extensively investigated, the role of tissue biomechanics ...
