Time sensitive biopharmaceutical processing updates can be implemented using lateral flow devices to test on-site during manufacturing. Lateral flow testing for an analyte such as, for example, impurities (e.g., host cell proteins), during manufacturing of a biopharmaceutical drug product is completed within twenty-five minutes of collecting a sample from the manufacturing line. That is, all sample preparation, such as adding reagent or diluting the sample, contacting the prepared sample to a lateral flow device, and detecting presence or absence of the analyte is completed within twenty-five minutes (e.g., 20 minutes, 18 minutes, 15 minutes) from collection such that processing adjustments during manufacturing can be implemented.

Methods and devices are disclosed for rapid, multiplex molecular detection of diverse nucleic acid target molecules. The invention features an electrophoretic array with immobilized hydrogel microgel deposits. Each deposit comprises a three-dimensional, cross-linked polymer matrix containing an immobilized affinity-binding molecule and a porogen-derived pore network. This structure is configured for rapid molecular transport of nucleic acids (e.g., up to 800 bp), providing a localized environment for target capture, ligation of linear Rolling Circle Amplification (RCA) probes, and RCA. Target-specific components are anchored within distinct microgels for multiplexing. Electric fields enhance transport, reaction kinetics, and amplicon concentration. Detection is achieved in under 20 minutes. The specifically structured and fabricated microgels improve detection speed, sensitivity, and applicability to multiple different targets.
