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 microcapsul
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.
1. A method for preparing secondary compounds comprising the steps of: (a) attaching a first set of primary compounds to one or more microbeads in a first aqueous fluid;(b) attaching a second set of primary compounds to one or more microbeads in a second aqueous fluid, wherein the second set of prim
1. A method for preparing secondary compounds comprising the steps of: (a) attaching a first set of primary compounds to one or more microbeads in a first aqueous fluid;(b) attaching a second set of primary compounds to one or more microbeads in a second aqueous fluid, wherein the second set of primary compounds is different from the first set of primary compounds;(c) forming a plurality of first water-in-fluorocarbon oil microcapsules by partitioning the first aqueous fluid with an immiscible fluorocarbon oil comprising a fluorinated surfactant, as the first aqueous fluid is flowing through a microfluidic channel, wherein the first aqueous fluid of each first water-in-fluorocarbon oil microcapsule comprises one or more first sets of primary compounds attached to one or more microbeads;(d) forming a plurality of second water-in-fluorocarbon oil microcapsules by partitioning the second aqueous fluid with the immiscible fluorocarbon oil comprising a fluorinated surfactant, as the second aqueous fluid is flowing through a microfluidic channel, wherein each aqueous fluid portion of the second water-in-fluororcarbon oil microcapsule comprises a second set of primary compounds attached to one or more microbeads;(e) merging the plurality of first water-in-fluorocarbon oil microcapsules with the plurality of second water-in-fluorocarbon oil microcapsules in presence of an applied electric field to form a plurality of merged water-in-fluorocarbon oil microcapsules in the microfluidic channel, wherein the immiscible fluorocarbon oil in the plurality of first water-in-fluorocarbon oil microcapsules and the plurality of second water-in-fluorocarbon oil microcapsules comprises a fluorinated surfactant and the aqueous fluid portion of each merged water-in-fluorocarbon oil microcapsule comprises a first set of primary compounds attached to one or more microbeads and a second set of primary compounds attached to one or more microbeads;(f) releasing, in the merged water-in-fluorocarbon oil microcapsules, the first set of primary compounds from the one or more microbeads and the second set of primary compounds from the one or more microbeads;(g) forming secondary compounds in the merged water-in-fluorocarbon oil microcapsules by chemical reactions between the released first set of primary compounds and the released second set of primary compounds, wherein the secondary compounds are present in the aqueous fluid portion of each of the plurality of merged water-in-fluorocarbon oil microcapsules;(h) fusing each merged water-in-fluorocarbon oil microcapsule with a third water-in-fluorocarbon oil microcapsule containing a target enzyme to form second merged water-in-fluorocarbon oil microcapsules containing the secondary compounds and the target enzyme, wherein one or more of steps (c) through (h) are performed under microfluidic control; and(i) determining subsets of the first set of primary compounds or the second set of primary compounds which react to form secondary compounds that bind to or modulate the activity of the target enzyme. 2. The method according to claim 1, further comprising: sorting the merged water-in-fluorocarbon oil microcapsules based upon identification of the secondary compounds that bind to or modulate the activity of the target. 3. The method of claim 1, wherein the first set of primary compounds and/or the second set of primary compounds are nucleic acids. 4. The method of claim 3, wherein each first water-in-fluorocarbon oil microcapsule comprises a single nucleic acid from each of the first set of primary compounds and the second set of primary compounds. 5. The method of claim 3, wherein said chemical reaction is a nucleic acid polymerization reaction. 6. The method of claim 1, wherein each of the first water-in-fluorocarbon oil microcapsules further comprises a cell. 7. The method of claim 6, wherein the target enzyme is associated with the cell. 8. The method of claim 7, wherein the target enzyme is in the cell. 9. The method of claim 1, further comprising merging each of the second merged water-in-fluorocarbon oil microcapsules containing the secondary compounds and the target enzyme with a fourth water-in-fluorocarbon oil microcapsule containing a fluorogenic substrate for the target enzyme. 10. The method of claim 1, wherein either the first set of primary compounds or the second set of primary compounds comprises a fluorogenic substrate for the target enzyme.
