NSF 2018: Rapid Assay Opens Door for Natural Indigo Dye and Other Bio-Based Chemicals

View Article

"For millennia, civilizations have extracted indigo dye from plants, creating a product that by the 18th century had become a driver of global economics. But, as the 20th century began, global output of natural indigo fell by over 90% as synthetic indigo took its place. With recent trends toward naturally derived alternatives for synthetic materials in processed foods, consumer goods, and other markets, the $427-million global market for indigo dye — whose synthetic building blocks include benzene, formaldehyde, and cyanide — represents an opportunity. Natural indigo dye and its parent agricultural crops could benefit from more than 100 years of advances in chemistry, chemical engineering, and agricultural science."
