Assessing UVA and Laser-Induced Crosslinking via Brillouin Microscopy. [PDF]
J 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.

Background-deflection Brillouin microscopy reveals altered biomechanics of intracellular stress granules by ALS protein FUS [PDF]
, 2018 Altered cellular biomechanics have been implicated as key photogenic triggers in age-related diseases. An aberrant liquid-to-solid phase transition, observed in in vitro reconstituted droplets of FUS protein, has been recently proposed as a possible ...

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 ...

Structural and elastic characterization of Cu-implanted SiO₂ films on Si(100) substrates [PDF]
, 2016 Cu-implanted SiO₂ films on Si(100) have been studied and compared to unimplanted SiO₂ on Si(100) using x-ray methods, transmission electron microscopy, Rutherford backscattering, and Brillouin spectroscopy.

Brillouin Optical Microscopy for Corneal Biomechanics [PDF]
Investigative Opthalmology & Visual Science, 2012 The mechanical properties of corneal tissue are linked to prevalent ocular diseases and therapeutic procedures. Brillouin microscopy is a novel optical technology that enables three-dimensional mechanical imaging. In this study, the feasibility of this noncontact technique was tested for in situ quantitative assessment of the biomechanical properties ...

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.

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.

Parallel imaging with phonon microscopy using a multi-core fibre bundle detection
Photoacoustics, 2023 In this paper, we show a proof-of-concept method to parallelise phonon microscopy measurements for cell elasticity imaging by demonstrating a 3-fold increase in acquisition speed which is limited by current acquisition hardware.
