Diversity and evolution of phycobilisomes in marine Synechococcus spp.: a comparative genomics study [PDF]

, 2007
Background Marine Synechococcus owe their specific vivid color (ranging from blue-green to orange) to their large extrinsic antenna complexes called phycobilisomes, comprising a central allophycocyanin core and rods of variable phycobiliprotein ...

Discriminatory identification of pigment class. [PDF]

, 2013
X indicates that the pigment of the row is readily soluble in the solvent of the column, or fluoresces under ultraviolet light. Lack of X indicates no visible extraction or fluorescence.

Optimisation and characterisation of the orange pigment produced by a cold adapted strain of Penicillium sp. (GBPI_P155) isolated from mountain ecosystem

Mycology, 2018
With globalisation and growing health risks of synthetic colourants, search for pigments from natural sources has increased owing to their non-toxic nature.

A multi-analytical approach to identify red colorants on woodblock prints attributed to Suzuki Harunobu

Heritage Science, 2022
Red organic dye identification is an important topic for conservation of Japanese ukiyo-e prints. Of particular interest are the works of Suzuki Harunobu, who was working at the inception of full-color printmaking.

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

Advanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

Bioactive Pigments of Monascus purpureus: Identification and Characterization

Journal of Food and Pharmaceutical Sciences
Monascus purpureus is a filamentous fungus that has long been recognized as one of the main producers of natural pigments. These pigments, including yellow (ankaflavin, monascin), orange (rubropunctatin, monascorubrin), and red (rubropunctamine ...

Ambient Light‐Activatable Luminescent Particle‐Embedded Conformal Patch for Photochemical Tissue Bonding and Photobiomodulated Healing

Advanced Materials, EarlyView.
We report a wearable photonic patch integrating room light‐ and sunlight‐activatable luminescent particles (RSLPs) for both photochemical tissue bonding and photobiomodulation. RSLPs harvest ambient light and emit red luminescence to drive chlorin e6–mediated collagen crosslinking.
