Evaluating the total gold concentration in metallic nanoparticles with a high c...
Godoy, Naiara Vieira, 1991-; Galazzi, Rodrigo Moretto, 1988-; Arruda, Marco Aurelio Zezzi, 1965-; Mazali, Italo Odone, 1972-Abstract: We report a complete set of strategies for characterization and an accurate determination of gold in metallic nanoparticles. For this, gold nanorods (AuNR) were synthesized by using the surfactant hexadecyltrimethylammonium bromide (CTAB) as the stabilizer and shape-directing agent. The surfactant CTAB forms a bilayer structure around the nanoparticles and became a challenge for the development of the...

Inductively coupled plasma mass spectrometry based platforms for studies involv...
Galazzi, Rodrigo Moretto, 1988-; Freitas, Daniel Carneiro, 1985-; Costa, Luana Ferreira da, 1987-; Arruda, Marco Aurelio Zezzi, 1965-Abstract: The widespread application of nanoparticles (NPs) in recent times has caused concern because of their effects in biological systems. Although NPs can be produced naturally, industrially synthesized NPs affect the metabolism of a given organism because of their high reactivity. The biotransformation of NPs involves different processes, including aggregation/agglomeration, and reactions with biomolecule...
In vitro bioaccessibility of metals from tape tea : a low-cost emerging drug

Comparison of generational effect on proteins and metabolites in non-transgenic...
Galazzi, Rodrigo Moretto, 1988-; Santos, Fábio Neves dos, 1986-; Eberlin, Marcos Nogueira, 1959-; Arruda, Marco Aurelio Zezzi, 1965-Abstract: This work evaluates different generations of transgenic (cp4-EPSPS gene) and non-transgenic soybean plants through proteomics and metabolomics. For proteomics purpose, 24 differentially abundant protein spots were found through 2-D DIGE, being 4 belonging to transgenic plants. From this total, 19 were successfully identified, storage proteins as predominant class. Some identified proteins are involved...
Sample preparation focusing on plant omics

Evaluation of some effects on plant metabolism through proteins and enzymes in ...
Galazzi, Rodrigo Moretto, 1988-; Lima, Tatiani Brenelli de, 1990-; Gozzo, Fábio Cesar, 1972-; Arruda, Marco Aurelio Zezzi, 1965-Abstract: To evaluate the effects of silver nanoparticles (AgNP) exposition, transgenic (through gene cp4EPSPS) and non-isogenic non-transgenic soybeans were cultivated in the presence or absence of AgNP or silver nitrate (AgNO3) at 50 mg/kg of silver. Physiological aspects of the plants including mass production and development of roots, proteomics such as protein amount and differential proteins, enzymes and ...
