This application provides a bead with a covalently attached chemical compound and a covalently attached DNA barcode and methods for using such beads. The bead has many substantially identical copies of the chemical compound and many substantially identical copies of the DNA barcode. The compound consists of one or more chemical monomers, where the DNA barcode takes the form of barcode modules, where each module corresponds to and allows identification of a corresponding chemical monomer. The nucleic acid barcode can have a concatenated structure or an orthogonal structure. Provided are method for sequencing the bead-bound nucleic acid barcode, for cleaving the compound from the bead, and for assessing biological activity of the released compound.

The present disclosure provides methods and systems for generation of libraries comprising two or more sets of molecules. Libraries may comprise sets of molecules of different types. Sets of molecules may be generated by attachment to supports. Different types of molecules may be generated combinatorially, thereby generating a large number of unique molecules. One or more types of molecules may be used to identify one or more additional types of molecules. Libraries of the present disclosure may be used in, for example, nucleic acid sequencing.

The present disclosure methods for identifying binding partners using cell surface display libraries, where the cells of the library display engineered peptides on their cell surfaces for identification of peptides that bind to targets of interest. The engineered peptides are preferably expressed in the cells under conditions that provide both secretion and display of the engineered peptides on the cell surfaces, thus providing access of the engineered peptides to identify potential binding pairs. The cell libraries cab be engineered using an automated editing system that provides for one or more targeted edits per cell.

The present disclosure provides instrumentation and automated methods for creating cell surface display libraries, where the cells of the library display engineered peptides on their cell surfaces for identification of binding pairs. The engineered peptides may be displayed using various cell surface display technologies.
