The skin-adherent sensor is an improved substitute for conventional sensors printed on plastic surfaces. It can be used for noninvasive detection and monitoring of body fluids present in sweat.
The tree is nature’s masterpiece
Are we paraphrasing Da Vinci here? In fact, Leonardo said it was the cat, but we respectfully changed it to trees (and, why not, plants at large)!
In a nutshell, we are a team of thinkers, at various levels of training, committed with mirroring the core elements of trees in our materials, fondly baptized as Matreerials.
After all, still quoting him, “the wisest and most noble teacher is nature itself”, with millions of top-notch R&D years before us.

Information and Updates on our Research Lines
Industrial waste is upcycled into biodegradable plastic
The product outperforms film made of HPMC alone. An article on the research project, which was supported by FAPESP, is published in the journal Applied Material & Interfaces.
Researchers have figured out how to stop bread from moulding without pumping it full of nasty chemicals
Instead of adding preservatives directly into or onto food, natural compounds can be added to packaging material, which then interact with the food to prevent spoilage — a technique called “active packaging.”
Matreerials’ ACS Applied Bio Materials paper is distinguished as ACS Editor’s Choice
The article Tailoring the Antimicrobial Response of Cationic Nanocellulose-Based Foams through Cryo-Templating was selected to be featured in the ACS Editors’ Choice initiative.

Tailoring colloids through supramolecular interactions: from fundamentals to applications
Funding: FAPESP (Thematic Research Grant)
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.

Combining the versatility of lyotropic liquid crystals with mechanical properties of nanocelluloses - relationship between microstructure and macroscopic properties
Funding: CNPq (Universal Research Grant)
Investigating the interaction of cellulosic nanomaterials in suspension with lamellar phases formed by surfactants, combining the properties of both components to obtain complex fluids.

Dispersion of cellulose nanocrystals in aqueous media
Funding: FAPESP (SPRINT) & Consortium of Alberta, Laval, Dalhousie and Ottawa (CALDO)
We will develop analytical tools for the quantification of interaction forces, macroscopic evaluation of the stability of CNCs, and chemical modification of CNCs.

Engineered biomaterials based on coconut oil and natural polymers: new ways to develop added-value biomedical products
Funding: FAPESP & Fundação para a Ciência e a Tecnologia (FCT, Portugal)
The project Nature4Health proposes to develop innovative biomaterials conjugating natural resources, namely agro-food product (VCO) and marine-origin polymers (CHT), by designing 2D (films) and 3D-based structures (oleogels, sponges) as high added-value wound care materials.

Use of bacterial nanocellulose in water-soluble edible polymer matrices
Funding: FAPESP (Regular Research Grant)
This project is expected to promote advances in solution characterization and interactional knowledge in colloidal systems composed of nanocellulose and biopolymers so that the study enables new applications of the obtained materials.

Biodegradable films from bulk fruit processing byproducts
Funding: FAPESP (Regular Research Grant)
The proposal involves the production of biodegradable films with active (antioxidant, antimicrobial and/or UV absorber) properties from bulk fruit processing byproducts.

Banana snacks as vehicles for probiotics
Funding: CNPq (Universal Research Grant)
Propõe-se o desenvolvimento de formulações de dois tipos de snacks probióticos de banana, a saber: um flexível e gomoso (fitas comestíveis) e outro quebradiço e crocante (banana liofilizada com revestimento probiótico).

Passive-sustainable climate-control strategies in a tropical climate using digital fabrication
Funding: CAPES/DAAD (PROBRAL)
This project aims at developing passive climate-control products based on phase-change materials and shading systems that can make light-weight construction perform better in tropical climates. This can lead to buildings with a lower carbon footprint both in terms of construction and operation.
