Novel insights on the physicochemical properties of eumelanins and their DMSO derivatives
(2016-11-01)
The biopigment eumelanin, ubiquitous in flora and fauna, is made up of chemically heterogeneous macromolecules based on the 5,6-dihydroxyindole and 5,6-dihydroxyindole-2-carboxylic acid building blocks. The exciting ...
In Situ Formation of Dendrites in Eumelanin Thin Films between Gold Electrodes
(2013-06-12)
Eumelanin is a ubiquitous pigment in the human body, animals, and plants, with potential for bioelectronic applications because of its unique set of physical and chemical properties, including strong UV-vis absorption, ...

Resistive switching controlled by the hydration level in thin films of the biopigment eumelanin
(Royal Soc Chemistry, 2016-01-01)
Melanins are biopigments ubiquitous in flora and fauna, exhibiting a range of interesting functional properties such as UV-Vis photoprotection, thermoregulation, hydration-dependent electrical conduction and metal chelation. ...
Replacing nitrogen by sulfur: From structurally disordered eumelanins to regioregular thiomelanin polymers
(Molecular Diversity Preservation International, 2017-10-17)
The oxidative polymerization of 5,6-dihydroxybenzothiophene (DHBT), the sulfur analog of the key eumelanin building block 5,6-dihydroxyindole (DHI), was investigated to probe the role of nitrogen in eumelanin build-up and ...
Growth and morphology of eumelanin thin films - A future bioelectronic material?
(2011-08-01)
We present a study on the thin film morphology and the optical properties of eumelanin resulting from different synthesis routes: the oxidation of tyrosine with hydrogen peroxide, the auto-oxidation of dihydroxyphenylanaline ...

Eumelanin thin films: Solution-processing, growth, and charge transport properties
(2013-08-21)
Eumelanin pigments show hydration-dependent conductivity, broad-band UV-vis absorption, and chelation of metal ions. Solution-processing of synthetic eumelanins opens new possibilities for the characterization of eumelanin ...
