It has been known for many years that dyes and pigments are subject to light-induced
degradation, or photodegradation, when exposed to light. It is the very reason why some …

(1) Background: Dyes play an important role in food, medicine, textile, and other industries,
which make human life more colorful. With the increasing demand for food safety, the …

Indigo and its derivatives are dyes and pigments with a long and distinguished history in
organic chemistry. Recently, applications of this 'old'structure as a functional organic …

The food and beverage industry is seeking to broaden the palette of naturally derived
colorants. Although considerable effort has been devoted to the search for new blue …

We describe the history of indigo dye and its derivative Tyrian purple, from their roles in the
ancient world to recent research showing the semiconducting properties of indigoids …

Indigo, one of the most ancient and abundant dyes in human history, has recently emerged
as a potential functional motif due to its intriguing photochemical properties. This review …

Heritage materials are highly complex systems of unknown and intrinsically heterogeneous
compositions and unmonitored long-term modifications. In this microreview, we describe our …

Recent advances in de novo protein design have delivered a diversity of discrete de novo
