Universidade de São Paulo (USP). Instituto de Química (IQ) (Institutional affiliation from the last research proposal) Birthplace: Brazil
Associate Professor at the Institute of Chemistry, USP, with expertise in organic physical chemistry and photochemistry. His research focuses on the chemistry of natural pigments, particularly betalains, hygrophorins, and melanins. In addition to exploring their properties, these secondary metabolites, found in plants and fungi, inspire the development of pseudo-natural derivatives and analogs with potential technological applications.

The present proposal aims to develop new smart and biocompatible organic-inorganic hybrid materials from both silica xerogels or aerogels silica containing flower pigments through the collaboration between the research groups of Prof. Fabiano Severo Rodembusch (UFRGS) and Prof. Erick Leite Bastos (USP), who have complementary expertises. The betalamic acid, the betalain precursor, will be…
The present project proposes studies in three important areas of photochemistry that will continue to take advantage of the unique and complementary expertise and facilities of the Swedish and Brazilian groups: (i) the investigation of the occurrence of proton-coupled electron transfer (PCET), excited-state intramolecular proton transfer (ESI) and photoisomerization of natural pigments an…
Betalains are chromoalkaloids found in plants and fungi that have been used as drugs, redox mediators, antioxidants and safe dyes. In this research project, we propose to: i) optimize the biotechnological production of betalamic acid, the biosynthetic precursor of betalains, ii) produce betalains anti-inflammatories that act at the level of NF-ºB and COX-1/COX-2, iii) develop betalamic ro…

Betalains are natural, water-soluble antioxidants that are used as coloring additives in foods and cosmetics, herbal agents, and mediators of redox transformations. The objective of this doctoral project is to produce and evaluate the biocompatibility of colored xerogels, cryogels, and aerogels made of silica-betalain. The betalains will be obtained through a green chemoenzymatic method a…
In this undergraduate research project, we propose to understand how natural and pseudo-natural betalains quench the fluorescence of the probe Hoechst 33342. Steady-state absorption and fluorescence spectra will be collected in the presence of indicaxanthin, betanin and OxiBeet, varying the pH of the medium in the range between 3 and 8. In addition, fluorescence lifetime measurements will…
This undergraduate research project aims to determine how surfactants of different classes influence the photoinduced decomposition of betalains. For this, betanin and indicaxanthin, natural betalains used as coloring in foods, will be used. The decomposition kinetics of betalains in aqueous media containing surfactants will be monitored during laser excitation around their absorption max…
Betalains are a class of pigments present in a wide variety of plants, fungi and bacteria.These natural products are widely used as colorants in the food industry and haverecently been used as antioxidants, redox mediators, and sensors. Obtaining betalains bychemical synthesis is a valuable strategy for creating functional pseudo-naturalderivatives. In this undergraduate research project,…

This Research Internship Abroad (RIA) Project aims to explore the use of pseudo-natural betalains and their derived materials as innovative tools for single-molecule localization microscopy (SMLM). Leveraging the reducing and fluorescent properties of these bio-based dyes, we seek to address the limitations of conventional fluorophores, which often lack biocompatibility and sustainability…
Anthocyanins, betalains, and carotenes are natural pigments that offer color to plant tissues, as well as function as antioxidants and photoprotectors. Carotenes help shield the photosynthetic machinery from photodegradation and are common in plants. In contrast, betalains and anthocyanins don't coexist in the same species in nature. Our team has developed hybrid dyes inspired by the chro…
Betalains are versatile natural pigments that has been used for the synthesis of metallic nanoparticles (NPs). These chiral secondary metabolites have also been found to interact with semiconducting nanoparticles and composites and to delay electron-hole recombination via the proton-coupled electron transfer (PCET) mechanism. In this research placement project, we propose to exploit the p…
Betalains are water-soluble imine/iminium natural pigments whose physicochemical properties can be tailored to specific applications. Depending on their chemical structure, betalains attached to nanostructured materials can promote electron hole transport via proton coupled electron transfer. We designed a photoresponsive and multifunctional betalain that can be covalently attached to met…
