Abstract: The invention concerns the field of microfluidics and in particular that of electrophoresis on a micro- or nanofluidic device. More particularly, the invention concerns the use of a reactive polymer coating adapted to be submitted to a phase separation under the influence of an external stimulation of chemical or physical type, to modulate the electrokinetic flows (electroosmotic or electrophoretic flows during electrophoresis for example) in a micro- or nanofluidic device. The invention also concerns a method for varying the electrokinetic flows in such a device using said coating, as well as the micro- or nanofluidic devices comprising at least one channel or one capillary tube whereof the inner surface is covered at least partly with such a coating.

Abstract: The invention relates to an end tool for a surgical instrument, comprising a tool-holder support (1) made from a rigid material including a flat face (2) or base layer adapted to support a tool, and a surgical tool (11) formed by a stack of elementary layers adapted to be firmly joined to one another so as to form a functional tool unit that can be positioned on and firmly joined to the base layer (2) of the tool-holder support.
