A method and reagent for constructing a nucleic acid double-linker single-strand cyclic library. The method comprises: breaking a nucleic acid into nucleic acid fragments; connecting a first linker sequence; producing by amplification a first product provided with the first linker sequence at either end, where a U nucleobase site is provided on primer sequences and a nicking enzyme recognition sequence is either provided or not provided on same, and a first affinity tag is provided on one of the primer sequences; using USER enzyme to cleave the first product; cyclizing the cleaved first product; treating the cyclization product with either a phosphatase or a nicking enzyme; using a solid-phase vector for combination with a cyclized molecule; performing a restrictive gap translation reaction; removing by digestion any portion that did not undergo the restrictive gap translation reaction; connecting a second linker sequence; producing by amplification a second product provided with the second linker sequence at either end; denaturing the second product, and cyclizing a single-strand nucleic acid molecule. The method allows an increase in the length of library insert fragments, a simplified library construction process, reduced library construction time, and reduced library construction costs.

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.

A device for synthesis of macromolecules is disclosed. In one aspect, the device comprises an ion-releaser having a synthesis surface comprising an array of synthesis locations arranged for synthesis of the macromolecules. The ion-releaser also includes an ion-source electrode, which is arranged to contain releasable ions and is arranged to be in contact with each of the synthesis locations of the synthesis surface, thereby release ions to the synthesis locations.
