Research in the field of Materials Science has advanced enormously in recent years, from an essentially applied, engineering-related approach to a position where it has great impact in other areas, including Physics, Chemistry, and Biology. This is mostly due to the advancement of theoretical and experimental techniques that have allowed us to probe, and interact with matter at the atomic…
Nanoscience and nanotechnology study the production, manipulation and applications of materials at the nanometric and atomic scale. The nanostructures have peculiar properties due to their size. Nanoparticles and other metallic nanostructures involve, at least in one dimension, tens to hundreds of tens of metal atoms which have very different characteristics in this arrangement in compari…
We characterized the peroxidase mechanism of recombinant rat brain cytoglobin (Cygb) challenged by hydrogen peroxide, tert-butylhydroperoxide and by cumene hydroperoxide. The peroxidase mechanism of Cygb is similar to that of myoglobin. Cygb challenged by hydrogen peroxide is converted to a Fe4+ oxoferryl p cation, which is converted to Fe4+ oxoferryl and tyrosyl radical detected by direc…
The peptidolytic enzyme THIMET-oligopeptidase (TOP) is able to act as a reducing agent in the peroxi-dase cycle of myoglobin (Mb) and horseradish peroxidase (HRP). The TOP-promoted recycling of the high valence states of the peroxidases to the respective resting form was accompanied by a significant decrease in the thiol content of the peptidolytic enzyme. EPR (electron paramagnetic reson…

Methylene blue and other thiazine dyes have relevance in a variety of applications covering the biological, materials, bioelectronics, and energy fields. Previous and ongoing studies in our laboratory have shown that the aggregate states of thiazine compounds acquire the property of stabilizing photochemically generated radical species. In the case of methylene blue, the stabilization of …
Biomolecules are useful for the green synthesis, stabilization, and mediation of the redox processes of metallic nanostructures, oxides, and materials with properties of topological insulators. Previous studies conducted by our group has shown two types of interactions of biomolecules with nanostructures. The redox center of cytochrome C, ferroprotoporphyrin IX, can act as electron accept…
Cell proteins undergoes turnover by means of digestion and the resulting amino acids are used for synthesis of new proteins. However, the digestion of proteins in cells generates peptides which, in specific cases, have signaling function and may lead to changes in the profile of gene expression and gene silencing. The cell degestion of proteins can occur in the proteassomes that degradate…

Methylene blue and other phenothiazinic dyes have relevance in various applications in biology, materials, bioelectronics, and energy fields. Previous and ongoing studies in our laboratory have shown that the aggregate states of phenothiazines modulate these dyes' photophysics and photochemistry, favoring the stabilization of cation radicals produced by the type I mechanism. Particularly …
The present project proposes to investigate the CISS (Chiral Induced Spin Selectivity) effect of the heme protein, cytochrome c, in the electron transport of semiconductors devices. Cytochrome c Fe(III) is photo-reduced by semiconductors such as hematite, zinc oxide, and titania materials. Also, electrochemical studies showed that cytochrome c provided an extremely high spin selectivity o…
