  "abstract": "A new extraction-free and non-destructive method to evaluate pigment content (chlorophyll a, chlorophyll b, and total carotenoids) in microalgae cells is introduced. It relies on the use of a spectrophotometer and an optical diffuser, together coined as the opal glass method. First, the practical aspects of the technique are consolidated (ease of setting up, usage of disposable cuvettes, speed of data acquisition, …). Then, a database is created to link opal glass spectra to microalgae pigment contents obtained by a methanol-extraction method. Partial Least Squares (PLS -machine learning) and Convolutional Neural Networks (CNN -deep",
