HIGH-THROUGHPUT PARALLEL RAMAN SPECTROMETER BASED ON SINGLE CELL DETECTION

摘要

Disclosed is a high-throughput parallel Raman spectrometer for cell detection. Specifically, the Raman spectrometer comprises: a movable platform (9) for placing a sample to be tested, which contains cells; a micro-imaging module for micro-imaging the sample to be tested; a laser focusing module for focusing a laser such that the laser is irradiated to a cell region to be tested, and a Raman signal is excited in a linear array multi-cell manner; a spectrum collection module for collecting a Raman signal generated by a cell irradiated by the laser focused through the laser focusing module; a collection planning and control module for controlling the movable platform to move along a planned route such that the spectrum collection module collects a Raman spectrum of linear-array cells; a Raman spectrum processing module for processing the Raman spectrum from the spectrum collection module to obtain a Raman spectrum signal corresponding to a single cell; and an output module for outputting a detection result.
