International audience; Thermophoresis denotes the motion of particles along temperature gradients. Insignificant in most daily-life observations, this peculiar effect can become dominant in applications involving nano-and microscale heating in fluid

Publikováno v: Quantitative Phase Imaging V.

In response to heat stress, triggered by a temperature increase of just a few degrees, cells activate a mechanism called the heat-shock response. While conventional global heating processes lead to an overall and slow increase of the temperature, hea

Laser heating of individual cells in culture recently led to seminal studies in cell poration, fusion, migration, or nanosurgery, although measuring the local temperature increase in such experiments remains a challenge. Here, the laser-induced dynam

To establish and maintain organ structure and function, tissues need to balance stem cell proliferation and differentiation rates and coordinate cell fate with position. By quantifying and modelling tissue stress and deformation in the mammalian epid
