Definitions
- the particular liquid used in the present invention is an ionic liquid or a mixture of ionic liquids.
- the present invention finds many applications, particularly in lab-on-a-chip where very small volumes of reaction media are generally used. It makes it possible, for example, to synthesize on a soluble support, syntheses in parallel, convergent syntheses, immobilizations on the ionic liquids of chemical or biological molecules that can be detected (target molecules) or detect (probe molecules), enzymatic reactions, homogenization of catalysts and homogeneous catalysts, process optimization, dangerous reactions, combinatorial chemistry reactions, etc.
- microsystems use drops of liquids in which the authors perform reactions. These microsystems are described for example in documents [4] and [5]. These drops of liquids may be aqueous or organic solvents.
- the present invention still meets this need, and still others, explained below, by providing a method for mixing drops of ionic liquid comprising the following steps: depositing a first drop of at least a first ionic liquid on a surface; depositing a second drop of at least one second ionic liquid on said surface; optionally introducing into the first ionic liquid, before or after its deposition in the form of a drop on the surface, of at least a first chemical or biochemical reagent; optionally introducing into the second ionic liquid, before or after its dropwise deposit on the surface, at least one second chemical or biochemical reagent; - meeting the first drop and the second drop so as to form a single drop.
- the present invention aims to provide a new use of ionic liquids as a microreactor, more particularly for applications in analytical techniques and chemical and biochemical reactions carried out on laboratories on a chip. It therefore also relates to a laboratory on a chip comprising at least one microreactor according to the invention.
- ionic liquids on the basis of which the present invention is implemented, have a number of interesting physico-chemical properties described in document [9]. These properties include: their low volatilities and very low vapor pressures: ionic liquids have very low volatility and very low vapor pressures, unlike Volatile Organic Solvents (VOS) and solvents. aqueous so no evaporation problem when used in droplet format. They are especially less volatile than water and most organic solvents such as, for example, ether, tetrahydrofuran, dichloromethane, chloroform, ethanol, methanol, toluene, acetonitrile, solvents whose temperature boiling point is less than or equal to 110 ° C.
- VOS Volatile Organic Solvents
- ionic liquids can also be cited, particularly for their interest in laboratory-on-a-chip applications: these liquids can be used in electrochemistry and have a large electrochemical window; and they are compatible with biological molecules such as enzymes, proteins, nucleic acids (DNA and RNA), glycoproteins, lipids, etc.
- ionic liquid means a pure ionic liquid or a mixture of ionic liquids, functionalized or not, or a mixture of one or more ionic liquids, functionalized or not, with one or more reagents and / or solvents.
- non-functional ionic liquid or

- n being an integer from 0 to 20.
- the drop (s) can (s) be deposited on the surface, for example of a lab-on-a-chip, by any known technique of the person skilled in the art, for example by a technique chosen from the group comprising a manual deposition, a deposition by an automated or non-automated drop dispenser, for example from an ionic liquid reservoir, or a deposition by fractionation of a larger drop deposited on the surface.
- the surface on which the drop is deposited is preferably a surface allowing the formation of a drop of ionic liquid without it spreading too much, especially in order to prevent contiguous drops whose coalescence was not expected to touch (unwanted contamination between drops deposited on the surface).
- It may be, for example, a silica surface, a glass surface, a Teflon surface, etc. This is in fact the surface on which the chemical or biochemical reaction is carried out using the drop microreactor of the present invention. It may be any surface suitable for making a lab-on-a-chip, and preferably compatible with ionic liquids.
- the material of the surface is therefore preferably compatible with the drop format and, where appropriate, with the chosen technique of displacement of the drop (s).
- the expression “the first and second drops are combined” means that at least two drops deposited on the surface can be combined, in particular to mix them and / or to mix their contents, for example the first and second reagents.
- first and second reagents means at least two reagents, each of the drops may comprise one or more reagents, each of the drops may consist of a functionalized or non-functionalized ionic liquid.
- the combination of the two drops, or coalescence can therefore trigger the chemical or biochemical reaction (s) or simply perform a mixture of reagents and / or ionic liquids.
- one of the drops comprises a specific task ionic liquid and the other a matrix ionic liquid and a reagent
- the meeting, or bringing into contact, of these drops of ionic liquid makes it possible to performing the desired chemical reaction (s) between the reagent and the function carried by the ionic liquid.
- the drop of the preceding step -iv- is combined with the drop of ionic liquid, for example by a displacement technique such as those mentioned above, and

- the matrix or functionalized ionic liquids used during the different reactions may be identical or different.
- said at least one first ionic liquid and said at least one second ionic liquid are independently selected from a functionalized or non-functionalized ionic liquid.
- the first ionic liquid may therefore comprise, in addition to the functionalized ionic liquid, an unfunctionalized ionic liquid, or else; in addition to the unfunctionalized ionic liquid, a liquid ionic functionalised.
- the second ionic liquid may comprise in addition to the functionalized ionic liquid, an ionic liquid. no . functionalized, or else, in addition to the unfunctionalized ionic liquid, a functionalized ionic liquid.

- Target molecules proteins, enzymes, nucleic acids (DNA and RNA), glycoproteins, lipids etc.
- probe molecules for example proteins, enzymes, nucleic acids (DNA and RNA), glycoproteins, lipids etc.

- An example of transport on a mobile support that can be used in the present invention is a "treadmill" as described for example in document [16].
- the dielectric layer and the hydrophobic layer between the activated electrode and the drop permanently polarized by a counter electrode, acting as a capacitor, - the effects of electrostatic charge induce the displacement of drop on the activated electrode.
- the counter electrode is essential for the movement by electrowetting, it maintains an electrical contact with the drop during its movement.
- This counter electrode can be either a catenary (Ca) as described in [5], or a buried wire, or a planar electrode on the hood of confined systems.
- the electrodes can be made by depositing a metal layer, by the
