QSpec: A Raman Spectrum Acquisition and Analysis System for Single-Cell


  • Introduction
  • QSpec is an open-source framework of microorganism single-cell experimental platform that could support the full cycle of single-cell phenotyping: instrument control (including RACS platform control and microfluidic device control), single-cell image analysis, single-cell Raman profiling, single-cell profile comparison, etc. QSpec is an easy-to-use, fully-customizable, memory-efficient, fast software package that could be run on a desktop computer. Based on this system, a single-cell Raman profile database has been established based on which some database search and data-mining works have been done to discover the heterogeneity among cells under different conditions and at different time-points during differentiation.
