The invention describes a method for the synthesis of compounds comprising the steps of: (a) compartmentalising two or more sets of primary compounds into microcapsules; such that a proportion of the microcapsules contains two or more compounds; and (b) forming secondary compounds in the microcapsules by chemical reactions between primary compounds from different sets; wherein one or both of steps (a) and (b) is performed under microfluidic control; preferably electronic microfluidic control The invention further allows for the identification of compounds which bind to a target component of a biochemical system or modulate the activity of the target, and which is co-compartmentalised into the microcapsules.

Compartmentalised combinatorial chemistry by microfluidic control

The invention describes a method for isolating one or more genetic elements encoding a gene product having a desired activity, comprising the steps of: (a) compartmentalising genetic elements into microcapsules; and (b) sorting the genetic elements which express the gene product having the desired activity; wherein at least one step is under microfluidic control. The invention enables the in vitro evolution of nucleic acids and proteins by repeated mutagenesis and iterative applications of the method of the invention.

The invention deals with a dispersion of drops of a first phase in a second phase substantially immiscible with the first phase, the solubility of the first phase in the second phase being less than 5% by mass. Each drop includes a core formed with a first phase and a shell formed with a coacervate layer interposed between the first phase and the second phase. The coacervate layer comprises a first precursor polymer of the coacervate and a second precursor polymer of the coacervate, one of the first phase and of the second phase is aqueous, and the other of the first phase and of the second phase is oily.

A capsule containing at least one mammalian cell, includes a liquid core, and at least one external envelope totally encapsulating the liquid core at its periphery, the external envelope including at least one gelled polyelectrolyte and/or a stiffened biopolymer and being able to retain the liquid core when the capsule is immersed in a gas. The present invention further relates to the method for preparing such a capsule, to a method for screening cosmetic active ingredients as well as a culture method using such capsules.

The invention describes a method for the identification of compounds which bind to a target component of a biochemical system or modulate the activity of the target, comprising the steps of: a) compartmentalising the compounds into microcapsules together with the target, such that only a subset of the repertoire is represented in multiple copies in any one microcapsule; and b) identifying the compound which binds to or modulates the activity of the target; wherein at least one step is performed under microfluidic control. The invention enables the screening of large repertoires of molecules which can serve as leads for drug development.

This method includes the provision of a first fluid () including the first phase and a first precursor polymer of the coacervate contained in the first phase, and the formation of drops of the first fluid () in a second fluid () intended to form the second phase (). It includes the steps of introducing a second precursor polymer of the coacervate into the second fluid () and, during the formation of each drop (), or once each drop () has been formed, for generating the coacervate layer by interaction between the first precursor polymer and the second precursor polymer at the interface between the first phase () and the second phase ().
