Abstract
A microfluidic surface processing system includes a microfluidic probe head having a processing fluid circuit configured to dispense a surface processing fluid from a processing fluid aperture thereof; a linkage mechanism, configured to apply a force to or modulate a force applied to the microfluidic probe head towards a surface to be processed; and a lifting fluid circuit integral with the microfluidic probe head and distinct from the processing fluid circuit, the lifting fluid circuit designed for dispensing a lifting fluid from a lifting fluid aperture thereof, with pressure such as to counter the force applied or modulated by the linkage mechanism, at the level of the surface.
