This project aims at achieving controlled association of varied colloids through either hydrophobic, electrostatic, or covalent bonds (or their combination) to tailor their characteristics, preferably in a reversible fashion. The envisaged functional colloidal objects span from surfactant and/or polymer aggregates, to nanoparticles of inorganic nature (mostly silica) or derived from renew…
This proposal aims at the complementary investigation of thermodynamics and ultrafast dynamics of polymer solvation (AU)
In order to produce stable and processable cellulose nanocrystals (CNCs), fundamental understanding of the relationship between the surface chemistry, interaction forces and colloidal stability of CNCs is necessary. We will develop analytical tools for the quantification of interaction forces, macroscopic evaluation of the stability of CNCs, and chemical modification of CNCs. By careful a…

This proposal aims at funding the visit of Prof Nadya P. da Silveira to IQ-Unicamp, for a period of around 5 months, to interact with projects being developed under the thematic project 2015-25406-5, fundamentally to bring her expertise in scattering techniques (both light and X-ray) for the investigation of different colloids.

Ophthalmological drug therapy is an interesting challenge for modern drug therapy. The anatomy, physiology and biochemistry of the eye makes it an accessible organ for foreign compounds. Therefore, it is common for drugs delivered to the eye to be ineffective or have limited effectiveness. To address this problem and ensure a better therapeutic efficacy of this route of administration, th…
To address the fundamental mechanisms of soil carbon (C) sequestration several expertise are needed in microbial ecology, geochemistry, physical and colloid chemistry. The emerging view of soil organic matter (SOM), the largest reservoir of C in terrestrial ecosystems, is that stability towards microbial activity is controlled by the biological and physicochemical environments and not by …

Nano-sized structures extracted from cellulose, also called nanocelluloses, have been extensively investigated in recent decades as potential rheological modifiers in different products. Another application is as mechanical property modifiers in polymer blends, in the form of composites. However, its interaction and rheological effects have been barely studied in other organized systems s…
The role of the project is to investigate the effect caused on the rheology of polyelectrolyte complexes upon the inclusion of gold nanoparticles in different concentrations and aspect ratios, as physical crosslinkers between the polymeric chains of the coacervate.(AU)
Nanoparticles formed by electrostatic complexation between opposite charge species have been extensively investigated in recent years due to their different functionalities. Complex coacervate core micelle (C3Ms) is one class of these nanoparticles that has a core-shell structure formed by mixing aqueous solutions of a copolymer with a macromolecule of opposite charges. A diversity of mac…

Inside cells, the functions performed by proteins and other biomolecules depend not only on their intrinsic characteristics, but also on properties of the medium, such as viscosity, water content and ion concentration. Many biological systems present the process of associative phase separation between polyelectrolytes, forming structures called membraneless organelles. This process can be…
Considering the need for the achievement of value-added compounds through optimized and environmentally correct processes, this project aims the development of interfacial catalytic systems for application in a variety of organic reactions. It will be obtained core-shell particles in aqueous medium from complex salts of dodecyltrimethylammonium and the block copolymer poly(acrylamide)-b-p…
The use of cellulose-based materials has been arousing great interest from both academia and industries as a result of the merged aspects related to sustainability, biodegradability, biocompatibility, and multifunctionality. Because of the promising combination among the outstanding potential for functionalization that is inherent to cellulose and the high specific surface area that is ty…

Inside cells, proteins and other biomolecules functions depend not only on their intrinsic characteristics, but also on the properties of the environment, like viscosity, water content and other related phenomena. However, it is curious that biomolecules remain stable and active inside the cell, but that outside this environment, they usually need special conditions to ensure their functi…
This research falls within the current scenario involving sustainable and multifunctional materials. Overall, it deals with the controlled deconstruction of the hierarchical architecture of chitin into nanochitin (NCh), which merges the inherent features of pristine chitin (renewability, biodegradability, biocompatibility, and biological activity, to mention a few) and the peculiarities o…
The proposed project aims the development of nanomaterials with specific and multiple functionalities. The idea is to prepare superparamagnetic iron oxide nanoparticles and functionalize their surfaces with different phosphonic acid-terminated polymers, combining the thermoresponsive PNIPAM (poly (N-isopropylacrylamide)) and PEO (poly(ethyleneoxide)) to modulate the nanoparticles interfac…
There is an increasing interest in the development of highly effective carriers for the delivery of cosmeceutical and pharmaceutical active ingredients. The field of nanostructured aqueous dispersions remains an area where further advances are required, especially the effective loading and the controlled delivery of bioactive materials (particularly peptides and proteins) (Yaghmur & Glatt…
