Raman-Enabled Predictions of Protein Content and Metabolites in Biopharmaceutical Fermentations.

Raman spectroscopy, a robust and non-invasive analytical method, has demonstrated significant potential for monitoring biopharmaceutical production processes. Its ability to provide detailed information about molecular vibrations makes it ideal for the detection and quantification of therapeutic proteins and critical control parameters in complex biopharmaceutical mixtures. However, its application in fermentations has been hindered by the inherent strong fluorescence background from the cells.
