APPARATUS AND METHOD FOR RAPID DETECTION OF ANALYTES

摘要

The system of the present disclosure is a system for real time, rapid detection of a target analyte in a liquid sample, the system comprising: a sample holder to hold the liquid sample wherein the sample holder is adapted and disposed for rotational motion; an optical source to provide an excitation light beam to excite a fluorescence marker in the sample to emit an emission light; an objective lens to focus the excitation light beam in the sample wherein at least a portion of the optical source is adapted and disposed for translational motion whereby the excitation light beam translates along at least a portion of the sample holder; a detector to record the intensity of the emission light over the period of time; and a member to calculate the number of cells or microorganisms in the sample from the recorded intensity of the emission light over the period of time.
