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 ca. 680 papers in refereed journals, which received ca. 17,800 citations (h = 59) in the Web of Science, and 27,000 citations (h = 75) in Google Scholar, in February, 2023, filed 12 patents, and supervised 52 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 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)

- Integrated dual electrochemical device for multiplexed detection of biomarkers, BP.PD
Abstract
The combination of electroanalytical methods and machine learning holds promise for the early diagnosis of cancer and other diseases, particularly with sensitive devices operating at the point of care. Even more reliable and complete results can be obtained with devices that simultaneously detect multiple biomarkers. However, producing these sensors free of label and external redox mediat…
- 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…

- Immunoassay for COVID-19 diagnosis based on surface-enhanced Raman scattering technique, BP.PD
Abstract
The control of the COVID-19 disease caused by the SARS-CoV-2 Coronavirus requires large-scale diagnosis for the population, mainly in the early stages of the infection.

Abstract
Mechanochromic materials have the potential to be used in the human motion monitoring since they can provide intuitive colorimetric responses discernible with naked eyes. However, the fabrication of functional wearables remains challenging because the mechanochromic effect is usually manifested in films that are difficult to be crafted into customized devices. It has been recently propose…

- 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…
