color="#000000">Spontaneous Brillouin scattering is based on the
interaction of photons with phase-matched acoustic phonons (sound
waves) inherently present in a sample. By detecting the spectral
shifts in the scattered light, which are in the order of 10 GHz, the
sample's hypersonic viscoelastic properties can be measured at
microscopic spatial resolution without physical contact. Brillouin
spectroscopy has long been known in material physics and environmental
sensing. However, its potential applications in biomedical sciences
have not been fully explored. We will discuss the recent development
of a highly efficient spectrometer and demonstrate the feasibility of
several promising applications including soft tissue biomechanics and
microrheology.</font></div>
