Final Report Summary - PHYSBOIL (Physics of liquid-vapor phase transition)
And unexpected application arose when we found that a laser pulse focused into a liquid-filled capillary can instantaneously produce a vapour bubble, which emits a shock wave, which then creates a thin, ultra-fast micro-jet (i.e. supersonic, up to 1000m/s). The jets can be 10 times smaller than the diameter of the micro-capillary. It is so fast that it shoots through skin, showing the potential of this method for needle-free injection.
Note for the ERC staff: I would not mind at all to make my whole summary of the project public, rather than only this short section.
