  • Brillouin Imaging for Studies of Micromechanics in Biology and Biomedicine: from Current State-Of-The-Art to Future Clinical Translation
    Brillouin imaging for studies of micromechanics in biology and biomedicine: from current state-of-the-art to future clinical translation Christine Poon1,2, Joshua Chou2, Michael Cortie1 and Irina Kabakova1* 1 School of Mathematical and Physical Sciences, Faculty of Science, University of Technology Sydney, Ultimo 2007, Australia 2School of Biomedical Engineering, Faculty of Engineering and IT, University of Technology Sydney, Ultimo 2007, Australia *corresponding author: [email protected] Abstract: Brillouin imaging is increasingly recognized to be a powerful technique that enables non- invasive measurement of the mechanical properties of cells and tissues on a microscopic scale. This provides an unprecedented tool for investigating cell mechanobiology, cell-matrix interactions, tissue biomechanics in healthy and disease conditions and other fundamental biological questions. Recent advances in optical hardware have particularly accelerated the development of the technique, with increasingly finer spectral resolution and more powerful system capabilities. We envision that further developments will enable translation of Brillouin imaging to assess clinical specimens and samples for disease screening and monitoring. The purpose of this review is to summarize the state- of-the-art in Brillouin microscopy and imaging with a specific focus on biological tissue and cell measurements. Key system and operational requirements will be discussed to facilitate wider application of Brillouin imaging along with current challenges for translation

  • Elastic Characterization of Transparent and Opaque Films, Multilayers and Acoustic Resonators by Surface Brillouin Scattering: a Review
    applied sciences Article Elastic Characterization of Transparent and Opaque Films, Multilayers and Acoustic Resonators by Surface Brillouin Scattering: A Review Giovanni Carlotti ID Dipartimento di Fisica e Geologia, Università di Perugia, 06123 Perugia, Italy; [email protected]; Tel.: +39-0755-852-767 Received: 17 December 2017; Accepted: 5 January 2018; Published: 16 January 2018 Abstract: There is currently a renewed interest in the development of experimental methods to achieve the elastic characterization of thin films, multilayers and acoustic resonators operating in the GHz range of frequencies. The potentialities of surface Brillouin light scattering (surf-BLS) for this aim are reviewed in this paper, addressing the various situations that may occur for the different types of structures. In particular, the experimental methodology and the amount of information that can be obtained depending on the transparency or opacity of the film material, as well as on the ratio between the film thickness and the light wavelength, are discussed. A generalization to the case of multilayered samples is also provided, together with an outlook on the capability of the recently developed micro-focused scanning version of the surf-BLS technique, which opens new opportunities for the imaging of the spatial profile of the acoustic field in acoustic resonators and in artificially patterned metamaterials, such as phononic crystals. Keywords: acousto-optics at the micro- and nanoscale; photon scattering by phonons; elastic constants of films and multilayers 1. Introduction The problem of a detailed knowledge of the elastic constants of thin film materials has attracted much attention in recent years, because of the growing importance of single- and multi-layered structures in advanced applications such as in devices for information and communication technology (ICT).

Three acoustic phonons propagating along the crystallographic b-axis were investigated over a temperature range of −185 to 175 ◦C. The temperature dependences of the sound velocity, the acoustic absorption coefficient, and the elastic constants were determined for the first time. The elastic behaviors could be explained based on normal lattice anharmonicity. No evidence for the structural phase transition was observed, consistent with previous structural studies. The birefringence in the ac-plane indirectly estimated from the split longitudinal acoustic modes was consistent with one theoretical calculation by using the extrapolation of the measured dielectric functions in the infrared range.

  • Surface Brillouin Scattering in Opaque Thin Films and Bulk Materials
    SURFACE BRILLOUIN SCATTERING IN OPAQUE THIN FILMS AND BULK MATERIALS Clemence Sumanya A thesis submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Doctor of Philosophy. Johannesburg, 2012 ii Abstract Room temperature elastic properties of thin supported TiC films, deposited on silicon and silicon carbide substrates and of single Rh-based alloy crystals, Rh 3Nb and Rh 3Zr, are investigated by the Surface Brillouin Scattering (SBS) technique. Velocity dispersion curves of surface acoustic waves in TiC films of various thicknesses, deposited on each substrate (Si and SiC) were obtained from SBS spectra. Simulations of SBS spectra of TiC thin hard films on germanium, silicon, diamond and silicon substrates have been carried out over a range of film thickness from 5 nm to 700 nm. The simulations are based on the elastodynamic Green's functions method that predicts the surface displacement amplitudes of acoustic phonons. These simulations provide information essential for analysis of experimental data emerging from SBS experiments. There are striking differences in both the simulated and experimental SBS spectra depending on the respective elastic properties of the film and the substrate. In fast on slow systems (e.g. TiC on silicon), the Rayleigh mode is accompanied by both broad and sharp resonances; in slow on fast systems (e.g TiC on SiC), several orders of Sezawa modes are observed together with the Rayleigh mode. The velocity dispersion of the modes has been obtained experimentally for both situations, allowing the elastic constants of the films to be determined. Effects of two deposition conditions, RF power and substrate bias, on the properties of the films are also considered.

  • Raman and Nuclear Resonant Spectroscopy in Geosciences
    Chapter 14 Treatise on Geochemistry Raman and Nuclear Resonant Spectroscopy in Geosciences Jung-Fu Lin Department of Geological Sciences, The University of Texas at Austin, Austin, TX, USA Ercan E. Alp Advanced Photon Source, Argonne National Laboratory, Argonne, IL, USA Alexander F. Goncharov Geophysical Laboratory, Carnegie Institution of Washington, DC, USA ABSTRACT Herein is presented a review of recent technical advances in Raman and nuclear resonance spectroscopy (both Mössbauer spectroscopy and nuclear resonant inelastic X- ray scattering spectroscopy (NRIXS)), as they have great implications for geoscience. Optical and X-ray spectroscopies probe different momentum and energy transfers caused by interactions between the incident light and the lattice, making them complementary and applicable to numerous scientific applications. Raman spectroscopy measures the optical vibrational modes at infinitely small momentum transfer whereas Mössbauer spectroscopy imparts negligible momentum transfer but can distinguish hyperfine interactions (quadrupole splitting, chemical shift, and magnetism) with neV energies. NRIXS measures the phonon density of states, which can be used to derive vibrational, thermodynamic, elastic, and electronic properties of the materials. Raman spectroscopy provides valuable and easily interpretable information about material properties using a 1 Chapter 14 Treatise on Geochemistry number of experimental platforms such as noninvasive tomographic imaging of minerals with sub-micrometer spatial resolution, in situ studies under extreme conditions of high pressure and temperature (P-T), and as a remote mineralogical and organic/biological probe for planetary exploration missions.

  • Non-Contact Mechanical and Chemical Analysis of Single Living Cells by Microspectroscopic Techniques
    Light: Science & Applications (2018) 7, 17139; doi:10.1038/lsa.2017.139 OPEN Official journal of the CIOMP 2047-7538/18 www.nature.com/lsa ARTICLE Non-contact mechanical and chemical analysis of single living cells by microspectroscopic techniques Sara Mattana1, Maurizio Mattarelli1, Lorena Urbanelli2, Krizia Sagini2, Carla Emiliani2,3, Mauro Dalla Serra4, Daniele Fioretto1,3 and Silvia Caponi5 Innovative label-free microspectroscopy, which can simultaneously collect Brillouin and Raman signals, is used to characterize the viscoelastic properties and chemical composition of living cells with sub-micrometric resolution. The unprecedented statis- tical accuracy of the data combined with the high-frequency resolution and the high contrast of the recently built experimental setup permits the study of single living cells immersed in their buffer solution by contactless measurements. The Brillouin signal is deconvoluted in the buffer and the cell components, thereby revealing the mechanical heterogeneity inside the cell. In parti- cular, a 20% increase is observed in the elastic modulus passing from the plasmatic membrane to the nucleus as distinguished by comparison with the Raman spectroscopic marker. Brillouin line shape analysis is even more relevant for the comparison of cells under physiological and pathological conditions. Following oncogene expression, cells show an overall reduction in the elas- tic modulus (15%) and apparent viscosity (50%). In a proof-of-principle experiment, the ability of this spectroscopic technique to characterize

  • Brillouin Spectroscopy
    BRILLOUIN SPECTROSCOPY What is Brillouin scattering? Brillouin scattering is named after Léon Nicolas Brillouin (1889-1969). The french physicist first predicted the inelastic scattering of light (photons) by thermally generated acoustic vibrations (phonons) in 1922. The soviet physicist Leonid Mandelstam (1879-1944) is believed to have discovered the scattering as early as 1918, but he published it only in 1926. Other commonly used names are Brillouin light scattering (BLS), Brillouin-Mandelstam scattering (BMS), and Brillouin-Mandelstam light scattering (BMLS). Mechanism In classical physics, Brillouin scattering can be described as reflection of the incident light from a three-dimensional diffraction grating produced by periodic density variations (refraction index changes) in a material due to propagating sound waves. Since the wave is traveling with the speed of sound, the scattered light frequency changes, too, it experiences a Doppler shift. The Doppler effect (or Doppler shift) is named after and was proposed by the austrian physicist Christian Doppler in 1842 in Prague, Czech Republic. It describes the frequency change of a wave for an observer moving relative to the source of the wave. The distance between two waves is called wavelength and the amount of time between waves passing is called frequency, which are interrelated by the wave traveling speed. High frequency indicates short wavelength and low frequency indicates long wavelength. During the approach of a wave at the observer the received frequency is higher than the emitted frequency, it is identical when the wave passes by, and it is lower during the decay of the wave. When the source of the waves is moving toward the observer, each successive wave is emitted from a position closer to the observer than the previous wave; each wave takes less time to reach the observer.
