Abstract
The present disclosure features portable wide field fluorimeter systems, e.g., in the form of low-cost mobile platforms, and methods to perform fluorometric assays to detect a change in fluorescence intensity in liquid samples, e.g., caused by the presence of a target analyte, e.g., a protein, e.g., an enzyme (e.g., β-lactamase) expressed by a target pathogen in a liquid sample in a point-of-care setting. In some implementations, a portable system for detecting a change in fluorescence intensity in a liquid sample includes a microfluidic device, an optical assembly including an emission filter and one or more lenses, and an analyzer device that collects and processes a fluorescent signal for the detection of a target analyte produced by the target pathogen present in the liquid sample.
