Using Raman imaging, wild-type and engineered yeast cells were compared for their ability to produce bioactive compounds. Raman imaging microscopy is able to visualize locales, relative abundance, and production efficiencies of biologically active compounds for the individual yeast cells.

The hyphenation of rheology and Raman spectroscopy enabled a more holistic depiction of the crystallization process and provided unique insights into the formation of cocoa butter polymorph form IV.
