The present disclosure relates to a closed loop aptamer development system that identifies one or more aptamers observed experimentally and implements machine-learning models to identify other aptamers not observed experimentally. Particularly, aspects of the present disclosure are directed to receiving a query concerning one or more targets, acquiring a library of aptamers that potential satisfy the query, identifying a first set of aptamers from the library of aptamers that substantially or completely satisfy the query, obtaining sequence data for the first set of aptamers, generating, by a prediction model, a third set of aptamers derived from the sequence data for the first set of aptamers, validating the third set of aptamers that substantially or completely satisfy the query, and upon validating the third set of aptamers and in response to the query, providing the third set of aptamers as a result to the query.

A method for identifying and characterizing biological parts based on omics datasets and a dual-fluorescent reporter gene system, and a biological part library constructed thereon are provided, relating to a technical filed of biology. The method includes steps of: identifying the biological parts using the omics datasets; constructing a single-fluorescent reporter gene system using a shuttle vector pEZ15Asp as a skeleton for screening and determining fluorescent reporter genes; obtaining a dual-fluorescent reporter gene system skeleton; constructing recombinant plasmids, and finally transforming into competent cells for quantitative analysis of fluorescence intensities. The present invention is convenient and quick, and can screen and identify different biological parts such as RBS, UTRs, promoters, and terminators of different intensities in batch quantitatively in a relatively short time. Moreover, the present invention can quickly expand the biological part library of Z. mobilis, so as to be applied in metabolic engineering of different demands.

Disclosed herein are methods for single-cell sequencing. In some examples, the methods include enriching a sample comprising a plurality of cells for cells of interest to produce an enriched cell sample; isolating one or more cells of interest in the enriched cell sample; and obtaining sequence information of one or more polynucleotides from each of the one or more isolated cells. Obtaining sequence information may include generating a molecularly indexed polynucleotide library from the one or more isolated cells. Enriching the sample may include focusing cells of interest in the sample using acoustic focusing.
