Laser Radiation Desorption Device For Manipulating a Liquid Sample in the Form of Individual Drops, Thereby Making It Possible to Carry Out the Chemical and Biological Treatment Thereof

A device for laser radiation desorption analysis of a liquid sample comprising drops, including means for moving said drops of said sample, and at least one means for routing the drops to at least one independent analysis pad, wherein said moving means, includes at least one conducting pad, covered by a partially wetting layer having at least one wetting zone opposite to the said conducting pad.

A device according to claim 1, wherein said wetting zones are functionalised chemically or biochemically.

An integrated system for the microfluidic analysis of a liquid sample that includes at least one means for preparing the liquid sample, wherein said preparation means includes a moving means for the introduction of the said sample and of reagents, and then their migration, to at least one means for the chemical or biochemical treatment of drops of said liquid sample, with said treatment means including means for moving said drops of said sample and then their migration to at least one means for analysis of the said drops of the said liquid sample, with the said analysis means being an analysis means by laser radiation desorption and including firstly means for moving the said drops of the said sample, and secondly at least one means for routing the drops to independent analysis pads, wherein at least one of said moving means includes at least one conducting pad covered by a partially wetting layer that includes at least one wetting zone opposite to said conducting pad.
