Direct Laser Writing of Polymer Nanocomposites for Tunable Structural Color

open access: yesAdvanced Materials, EarlyView.
Herein, direct laser writing is used to polymerize self‐assembled nanocomposite materials. Using fabrication parameters, the interparticle spacing is finely tuned beyond the thermodynamically stable state. This is exploited to generate wide gamut structural color in water.

GENES DETERMINING THE SYNTHESIS OF LAVONOID AND MELANIN PIGMENTS IN BARLEY

open access: yesВавиловский журнал генетики и селекции, 2018
In addition to the green color caused by chlorophyll, grain and vegetative organs of barley can be colored by compounds of phenolic nature, such as melanins and lavonoids, which include anthocyanins, proanthocyanidins. Due to the wide biological activity

Stimuli‐Responsive Materials for Biomedical Applications

open access: yesAdvanced Materials, EarlyView.
Stimulus‐responsive materials (SRMs) hold great promise for use in a wide range of biomedical applications. This review covers four stimulus modalities, namely, electrical, optical, magnetic, and ultrasound, and their associated SRMs. It provides a summary of the materials in each modality, their development, and current research perspectives.

Effect of Nanoparticle Distribution on Photothermal Absorption in Binary Mixtures of Colloidal Supraballs

open access: yesAdvanced Photonics Research, EarlyView.
This work combines molecular dynamics and finite‐difference time‐domain computational approaches to study the photothermal properties of melanin nanoparticle–based supra‐assemblies. Based on the results of this study, the binary mixtures of melanin and silica with higher concentrations of melanin and with more segregated levels of mixing are able to ...

Biochemistry and biosynthesis of insect pigments

open access: yesEuropean Journal of Entomology, 2014
The functional role and commercial importance of insect pigments have been studied for well over a century. They are classified into those synthesized by insects, which include anthraquinones, aphins, pterins, tetrapyrroles, ommochromes, melanins and ...

Inhibitory effect of enzymatic browning products on trypsin activity [PDF]

open access: yes, 2011
The aim of this piece of work was to assay if the melanins synthesized from  Agaricus bisporus polyphenol oxidase and one of its main substrates (L-tyrosine) act as trypsininhibitors, and therefore may have a toxic effect on protein digestion.

Insect‐Microbe‐Based Laccase: Untapped Natural Resource for Industrial and Biotechnological Applications

open access: yesAdvanced Sustainable Systems, EarlyView.
The insect‐microbe interplay fulfills a key ecological role involving the degradation of ligninocellulose biomass. This is coordinated by the secretion of different kinds of proteins, of which ligninolytic enzymes, such as laccases (Lacs), are of prime importance.
