Cells exert, sense, and respond to the different physical forces through diverse mechanisms
and translating them into biochemical signals. The adhesion of cells is crucial in various …

In this article we first present the foundations of ultrafast photoacoustics, a technique where
the acoustic wavelength in play can be considerably shorter than the optical wavelength …

Membrane viscosity is an important property of cell biology, which determines cellular
function, development and disease progression. Various experimental and computational …

Using time-resolved x-ray diffraction, we demonstrate the manipulation of the picosecond
strain response of a metallic heterostructure consisting of a dysprosium (Dy) transducer and …

Physical forces and other mechanical stimuli are fundamental regulators of cell behavior
and function. Cells are also biomechanically competent: they generate forces to migrate …

We present a picosecond optoacoustic technique for mapping both the longitudinal sound
velocity v and the refractive index n in solids by automated measurement at multiple probe …

Cells sense and respond to external physical forces and substrate rigidity by regulating their
cell shape, internal cytoskeletal tension, and stiffness. Here we show that the combination of …

We report on elasticity measurements in neuronlike cells using picosecond acoustics pump
and probe spectroscopy. The stimulated Brillouin oscillations were mapped in PC12 cells to …

The single cell eukaryotic protozoan Acanthamoeba castellanii exhibits a remarkable ability
to switch from a vegetative trophozoite stage to a cystic form, in response to stressors. This …

Time-domain Brillouin scattering (TDBS) is an all-optical experimental technique for
investigating transparent materials based on laser picosecond ultrasonics. Its application …
