TL;DR: It is reasoned that novel, mild, biocompatible approaches could be developed to establish a metal-free route to tunable, nature-inspired, long-lasting coloration of human hair, which has the potential to replace classical harsh hair dyeing conditions that have raised concerns for several decades due to their potential toxicity.

TL;DR: In this paper, the brightness of gold nanoparticles has been investigated and different approaches have been proposed to enhance this poor photoluminescence quantum yield aiming to achieve ultra-bright gold nano-dots with features superior to conventional dyes.

TL;DR: Rational structural modification of a well-known molecular fluorophore N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl) (NBD) produces fluorophores that self-assemble in nanoparticles in the biocompatible environment without any dramatic decrease of the fluorescence quantum yield.

TL;DR: One of the most unusual features of melanin is the presence of stable persistent radicals as mentioned in this paper, which has been reported to relate to the properties of the melanin's melanin pigments.

TL;DR: In this paper, a perylene-diimide (PDI) based probe was used for the direct detection of microplastics in water without any further treatment of the sample.
