The present invention concerns a microfluidic device for mechanically induced trapping of molecular interactions comprising at least a first unit cell and a second unit cell, each unit cell comprisinga membrane chamber comprising a membrane, a flow channel crossing the membrane chamber and having an inlet and an outlet, and the flow channel crossing the first unit cell being different from the flow channel crossing the second unit cell. Another object of the invention is a method for isolation of specifically bound nucleic acids to target molecules on said microfluidic device followed by its recovery and identification.

Multi-stage sample-recovery systems, including automated 2-stage and 3-stage sample-recovery systems, are provided. Such systems enable the rapid screening and recovery of samples, including viable cell-based samples, from high-throughput screening systems, including systems utilizing large-scale arrays of microcapillaries. In specific screening systems, each microcapillary comprises a solution containing a variant protein, an immobilized target molecule, and a reporter element. Immobilized target molecules may include any molecule of interest, including proteins, nucleic acids, carbohydrates, and other biomolecules. The association of a variant protein with a molecular target is assessed by measuring a signal from the reporter element. The contents of microcapillaries identified in the assays as containing variant proteins of interest can be identified and recovered using the multi-stage systems disclosed herein.

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 product is used as a chemical input for each of the reactions in a second series of reactions. The products of the second series are analysed. 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. Each reaction in the first series differs in one or more chemical and/or physical inputs. Each reaction in the second series differs in one or more chemical and/or physical inputs. The invention also provides an automated exploration apparatus for performing the method, and the apparatus comprises a controller, and a chemical synthesiser and an analytical unit which are operable by the controller, as described herein.

Systems and methods for querying a combinatorial synthesis library comprising a plurality of compounds and representing a plurality of reaction types, where each reaction type maps to a plurality of reactants, and each reactant maps to a plurality of synthons, accepts a query in the form of a single graph into a molecular encoder model, thereby obtaining a query vector. The query vector is inputted into a reaction query generator model thereby obtaining a first reaction type and a first plurality of reactants. A synthon is determined for each reactant by inputting the reactant into a synthon query generator model. A set of synthons is therefore determined, each corresponding to a reactant in the first plurality of reactants. A molecular structure in the combinatorial synthesis library is identified that includes the set of synthons arranged in accordance with a synthesis rule associated with the first reaction type.
