Osvaldo N. Oliveira Jr. is a physicist, with BSc and MSc from the Universidade de São Paulo, Brazil, and PhD from University of Wales, Bangor (1990). In 2019 he received the Doctor Honoris Causa degree from the Federal University of Mato Grosso do Sul, Brazil. He is the director of Sao Carlos Institute of Physics, University of Sao Paulo, Brazil. He published over 640 papers in refereed journals, which received ca. 16,100 citations (h = 58) in the Web of Science, and 24,200 citations (h = 71) in Google Scholar, in March, 2022, filed 12 patents, and supervised 50 MSc and PhD students. Prof. Oliveira has led research into the fabrication of novel materials in the form of ultrathin films obtained with the Langmuir-Blodgett and self-assembly techniques. Most of this work has been associated with fundamental properties of ultrathin films with molecular control, but technological aspects have also been addressed in specific projects. This is the case of an electronic tongue, whose response to a number of tastants is considerably more sensitive than the human gustatory system. Prof. Oliveira has helped establish the Núcleo Interinstitucional de Linguística Computacional (NILC), which is a leading institute for natural language processing of Portuguese. Research and development activities at NILC include the development of a grammar checker for Brazilian Portuguese, which was available worldwide through Microsoft Word for many years, and participation in the Universal Networking Language (UNL) Project, sponsored by the United Nations University. He published two books on outreach activities and edited a book on scientific writing. In recent years, Prof. Oliveira has pioneered the combined use of methods from distinct fields of science, with the merge of methods of statistical physics and computer science to process text, and use of information visualization to enhance the performance of sensing and biosensing. Prof. Oliveira was the president of the Brazilian Materials Research Society from 2016 - 2020, and is the vice-president of the International Union of Materials Research Societies (IUMRS). He is a member of the Brazilian Academy of Sciences, and executive editor of ACS Applied Materials & Interfaces. In 2006 he was awarded the Scopus Prize, given to 16 Brazilian researchers considered the most productive in terms of papers published and citations. (Source: Lattes Curriculum)

Abstract
Dr. Paulo António Ribeiro has been a research partner of the Bernhard Gross Polymer Group for many years since he did his PhD. in our group in the 1990s. Since then, we have maintained collaboration that in recent years has focused on the properties of films and interaction of DNA with Langmuir films. In this collaboration, we seek complementarity of knowledge and infrastructure for the p…
- Polymer layers with embedded metal nanoparticles: building blocks for (bio)sensors, AV.EXT
Abstract
This project aims at the development of hybrid materials consisting of a nanostructured polymeric matrix film with embedded well-defined metal nanoparticles (NPs). Here, a polymeric layer-by-layer structure encompassing self-healing and anti-corrosion properties will ensure protection of the metal NPs pre-formed by physical methods and deposited from the gas phase. Such materials are expe…

- Biosensors made with polymer films incorporating metallic nanoparticles for clinical diagnosis, BP.PD
Abstract
The manufacture of low-cost, large-scale biosensors is a necessity to assist in the early diagnosis of many diseases, such as cancer, and to detect infections such as COVID-19. A method used to increase the sensors' sensitivity and selectivity is the incorporation of metallic nanoparticles in the polymeric matrix on which the active layer of the biosensor is deposited. This is usually ach…
- Encapsulation of antitumoral ruthenium complexes into calixarene derivatives: a study of drug delivery systems and cell membrane models, BP.PD
Abstract
Ruthenium complexes have shown high toxicity against several tumor cell lines, but they are also toxic to healthy cells. Their efficient use in chemotherapy will only occur if they are encapsulated in biocompatible nanostructured carriers, such as those obtained with calixarenes. In this project, we will investigate the encapsulation of ruthenium complexes in drug delivery systems with de…
- Coloured patterns based on bioinspired photonic crystals for mechanocromic applications, BP.PD
Abstract
Photonic Crystals (PCs) are periodically organized dielectric nanomaterials that have a Photonic Band Gap (PBG) superimposed on the visible light regime. The simplest strategy for preparing PCs is the self-organization of spherical monodisperse nanoparticles via sedimentation of colloidal suspensions. Despite having vivid structural colors, this class of materials is fragile, and only fla…

- SB-spinning and supersonic nanoblowing biopolymer nanofiber mats for in situ removal of heavy metal ions, BE.EP.PD
Abstract
Heavy metals are known to cause serious diseases in humans by threatening their nervous and cardiovascular systems, to mention a few, even at low concentrations. Many materials have been developed for heavy metal ion removal. However, most of them have low adsorption rates and may take a long time to achieve adsorption equilibrium. Furthermore, there are concerns about the use of non-biod…

Abstract
Detection of harmful gases is an important requirement for the control of atmospheric and environmental pollution, and vehicle emissions. Such detection has been mostly done with gas sensors made with nanostructured metal oxides, whose optimized operation temperature is high (200~350ºC). Another drawback of these gas sensors is lack of selectivity. The design and fabrication of room tempe…
