The invention provides a method for the exploration of chemical space through a multigenerational series of synthetic stages. In a first stage, a series of reactions is performed. The products of the first series are analysed, and a first product from the series of reactions is selected.

The first and second stages are performed autonomously. The selection of a product in the first stage comprises the comparison of the products from the first series of reactions against a fitness function, where the selected product has a superior fitness compared with one or more other products in the first series.

A method for DNA synthesis using protected nucleosides is disclosed. The nucleosides may be nucleoside triphosphates or nucleoside phosphoramidites with nucleobases attached to electrochemically-cleavable linkers. Removal of a protecting group by application of a voltage in solution triggers a cyclization reaction that cleaves the electrochemically-cleavable linkers. The electrochemically-cleavable linkers may include an amide linkage and an amide that forms a lactam or an ester linkage and a protected alcohol that forms a lactone when the protecting group is removed. The voltage used to cleave the electrochemically-cleavable linkers may be generated by activation of individual electrodes on a microelectrode array. The microelectrode array can be a substrate for solid-phase synthesis of oligonucleotides. Activation of specific electrodes removes the protecting groups at those electrodes and thus enables spatially-controlled extension of the oligonucleotides. Protected nucleosides linked to protecting groups by electrochemically-cleavable linkers are also disclosed.

Embodiments disclosed herein are directed to microfluidic devices that allow for scalable on-chip screening of combinatorial libraries and methods of use thereof. Droplets comprising individual molecular species to be screened are loaded onto the microfluidic device. The droplets are labeled by methods known in the art, including but not limited to barcoding, such that the molecular species in each droplet can be uniquely identified. The device randomly sorts the droplets into individual microwells of an array of microwells designed to hold a certain number of individual droplets in order to derive combinations of the various molecular species. The paired droplets are then merged in parallel to form merged droplets in each microwell, thereby avoiding issues associated with single stream merging. Each microwell is then scanned, e.g., using microscopy, such as high content imaging microscopy, to detect the optical labels, thereby identifying the combination of molecular species in each microwell.
