The major innate defence system of the airways is mucociliary clearance. To move mucus unidirectionally out of the airways, the cilia, micrometre-long hair-like projections on airway epithelial cells, embedded in the periciliary layer, a dense mucin glycopolymer network, beat in a metachronal manner. Inspired by this biological example, we will develop synthetic mimics of the functional c…
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…

The activities that will be carried out during Professor Sarah Perry's visit are directly related to the development of collaborative work between the research groups at IQ-Unicamp and the University of Massachusetts Amherst (UMass - United States). The collaboration with Professor Sarah Perry's group began in 2022 with the internship of student Julia Sabadini (2021/11317-1) and it involv…
Monitoring changes in the self-associated systems of surfactants and electrolyte complexes during digestion can provide information on the complex molecular interactions that can occur in biological systems. However, static instrumentation can be a limitation for evaluating dynamic processes in flow. In this way, we propose the use of in situ time-resolved small-angle X-ray scattering tec…

Este projeto tem por objetivo controlar a associação de diferentes coloides através de forças hidrofóbicas, eletrostáticas ou covalentes (ou de suas combinações) para modular suas propriedades, preferencialmente, de maneira reversível. Os sistemas coloidais a serem estudados variam de agregados de surfactantes/polímeros a nanopartículas inorgânicas (principalmente sílica) ou derivadas de …
Coacervates are systems formed by liquid-liquid phase separation (LLPS). This phase separation typically occurs by interaction between oppositely charged polyelectrolytes in an aqueous medium, generating a highly hydrated environment (65-85% water) containing the polymers, which closely mimics the intracellular environment, and another with simple ions. Membraneless organelles are biologi…
Neste projeto, pretendemos implementar e comissionar medidas com a técnica de RheoSAXS e com medidas em fluxo contínuo (incluindo sistemas microfluídicos) acoplados a este equipamento.As medidas de RheoSAXS permitirão complementar as análises estruturais obtidas por SAXS convencionais de sistemas organizados, agora sob cisalhamento controlado. Dentro do projeto temático vinculado, esta d…

Vitrimers are polymeric materials that have properties similar to those of thermosets, such as dimensional, mechanical and thermal stability and insolubility. This dynamic exchange can be triggered by temperature, light or microwave, depending on the chemical groups involved in the cross-linking. The presence of dynamic reticulation nodes makes the three-dimensional polymeric network capa…
Mimicking nature has been an important strategy for the development of synthetic structures with characteristics like the structures found in living beings. Proto-organelles, protocells and prototissues are defined as synthetic structures that mimic their biological analogues and their recent development has provided advances in biomaterials. This project aims at the preparation of multic…
The coacervate phase is formed by a high water content (typically 65-85%), some simple ions, as well as polyelectrolytes, which mimic the intracellular environment very well. Coacervates can be confined to a nanometer domain if one of the components of the coacervate consists of a diblock copolymer containing one of the blocks electrically charged. In this case, the result is a core-shell…

Biobased solid polymer electrolytes (SPEs) offer a promising pathway toward safer and more sustainable energy storage compared to conventional flammable liquid electrolytes used in Li-ion batteries. Polysaccharides, such as cellulose and chitosan, are particularly attractive building blocks due to their abundance, renewability, biodegradability, and unique physicochemical properties arisi…
Petroleum-based polymers are commonly used as additives to tailor specific properties or functionalities in formulations. Bio-based biodegradable polymers, such as polysaccharides, have been proposed as an alternative to preparing more sustainable formulations, including, in this scenario, the use of nanocelluloses. On the other hand, surfactants are molecules highly present in different …
Nanoparticles formed by electrostatic complexation between oppositely charged species have been extensively investigated in recent years due to their different functionalities. In this area are the complex coacervate core micelle (C3M), formed by the mixture of aqueous solutions of a copolymer with an oppositely charged macromolecule. The process of formation, characterization, and applic…
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…
