1. Superparamagnetic maghemite loaded poly (ε- caprolactone) nanocapsules : characterization and synthesis optimization
Iron oxide nanoparticles (ION) have been studied for essential applications, like detection of biological constituents (virus, bacterials, cell, nucleic acids, protein, enzyme, etc.), magnetic bioseparation and clinic therapy and diagnosis (such as MRI magnetic fluid and hyperthermia). In this work, γ-Fe2O3has been synthetized by a adapted sol-gel method a

2. Nanocompósitos magnéticos: potencialidades de aplicações em Biomedicina
The synthesis of magnetic materials such as nanostructured iron oxide has been intensively researched due to their broad applications in biomedicine. As these nanoparticles have high specific surface area, they are very reactive and can aggregate easily, and biodegrade when exposed to biological systems. Mesoporous silica is often employed as support matrix

3. Cromatografia negativa em Sepharose-TREN como tecnica de purificação de proteinas adicionadas artificialmente a extrato de soja / Negative chromatography on Sepharose-TREN as a technique of proteins purification artificially added to soybean extract
In recent years, plants have been studied as bioreactors for the production of recombinant proteins with industrial and pharmaceutical interest. When compared to other expression systems, plants have several advantages, such as the possibility of posttranlationals modification, low production cost, low risk of contamination by human pathogens, and the accumu

4. Functional properties of egg white proteins of quail egg / Propriedades funcionais de proteínas da clara do ovo de codorna
In this work, the functional characteristics of solubility, capacity of foam formation and gelation of the egg white proteins of quail egg were studied. Solubility data were evaluated in function of the stirring time of the proteic solution, the pH value and the salt concentration (NaCl), at 25 C. The foam and gelation properties were analyzed as a function

5. Recuperação e purificação de enzimas usando adsorção em leito expandido
This work deals with the application of Expanded Bed Adsorption (EBA) to recovery and purify enzymes. Model proteins, lisozyme and bovine serum albumin (BSA), as well as some enzymes, glyceraldehyde 3-phosphate dehydrogenase (G3PDH) from baker s yeast, xylanase (from a commercial extract) and chitosanase from Bacil/us cereus were used to study the EBA backgr
