At low frequencies ultrasound is a valuable tool to mechanically characterize and image
biological tissues. There is much interest in using high-frequency ultrasound to investigate …

Characterization of the elasticity of biological cells is growing as a new way to gain insight
into cell biology. Cell mechanics are related to most aspects of cellular behavior, and …

Brillouin light scattering (BLS) is an emerging method for cell imaging and characterisation.
It allows elasticity-related contrast, optical resolution and label-free operation. Phonon …

The mechanical properties of cells play a key role in several fundamental biological
processes, such as migration, proliferation, differentiation and tissue morphogenesis. The …

Cell morphological analysis has long been used in cell biology and physiology for
abnormality identification, early cancer detection, and dynamic change analysis under …

Advances in microscopy with new visualization possibilities often bring dramatic progress to
our understanding of the intriguing cellular machinery. Picosecond optoacoustic micro …

This work aims at demonstrating the ability of an acoustic linear code to model the
propagation of a shock wave created by a laser impact over a metallic surface. In this …

In order to work at higher ultrasonic frequencies, for instance, to increase the resolution, it is
necessary to fabricate smaller and higher frequency transducers. This paper presents an …

By means of a metal opto-acoustic transducer we generate quasi-longitudinal and quasi-
transverse picosecond strain pulses in a (311)-GaAs substrate and monitor their …

We have developed a high-sensitivity, low-noise femtosecond imaging technique based on
pump-probe time-resolved measurements with a standard CCD camera. The approach used …
