He has a degree in Chemistry with Technological Attributes (2001), a master's degree (2004), and a PhD (2007) in Chemistry (Concentration Area: Analytical Chemistry) from the University of São Paulo (2004). He is currently a Full Professor at the Institute of Chemistry of the University of São Paulo and coordinates the Laboratory of Electronic Tongues and Chemical Sensors based at the same Institution. He has experience in the development of chemical sensors and electronic tongue sensor arrays aimed at solving analytical problems in environmental, clinical, forensic, and food areas. Between 2009 and 2022, he had 15 projects approved and funded by CNPq, FAPESP, ONGR, and CAPES. He was the Coordinator of the Chemistry Area at CAPES (2022-2024), with a renewed mandate for the four-year period 2023-2026, and was a full member of the Technical-Scientific Council of Higher Education (CTC-ES) at CAPES in 2022. He has been the President of the Postgraduate Commission of the Institute of Chemistry of the University of São Paulo between 2018 and 2022, as well as the Coordinator of the Postgraduate Program in Chemistry between 2014 and 2018. He supervised 5 master's dissertations, 10 doctoral theses, and oversaw 5 postdoctoral fellows. In early 2018, he was appointed an affiliate member of the Brazilian Academy of Sciences in the category for young scientists, and from 2024, he became an Associate Editor of the journal Analytica Chimica Acta. Since 2024, he has been serving as an Advisor to the Scientific Directorate of FAPESP and as an Advisor for the Ethics and Research Integrity Program at the same institution.

The research project focuses on the fabrication and implementation of integrated miniaturized systems for the online monitoring of chemical species of environmental, biological, industrial, and clinical interest. The proposed devices will consist of miniaturized electrochemical, physical, and optical sensors, and emphasis will be given to constructing prototypes with high robustness and c…
Analytical chemistry techniques and technologies have rapidly emerged in the last years, but the cost and logistics for the samples collection at meaningful spatial scales and further analysis does not make their development and spread straightforward. Such problems can be better addressed by the fabrication of devices that operate autonomously at or near the sampling site, reducing the r…
Paixão and Hashemi propose to combine synergies and to produce a one-of-a-type paper-based device for fast trace analysis in-situ, applied to environmental systems and even biological systems (blood tests). The initial work, proposed below, will yield prototype devices that the PIs propose to a) use as preliminary work towards larger grant applications and b) commercialize. (AU)

Wearable devices are a promising alternative with regard to continuous monitoring and clinical diagnosis of diseases in affected individuals, providing analyzes directly on the human body in real time, without the need for sample preparation or laboratory infrastructure. Most of these devices focus mainly on applications aimed at the health area, to monitor various pathogens and diseases …
The search for portable devices that allow the development of environmentally safer analytical methods and real-time information collection to carry out "in loco" analyses is a current trend in analytical chemistry. Microfluidic systems are an attractive strategy to achieve these goals. In addition to allowing studies with low sample volumes, they enable the integration of analytical step…

The work plan described here aims to present a proposal of the activities to be developed during the postdoctoral stage at the Institute of Chemistry of the University of São Paulo. The project proposes the development of wearable sensors through the integration of low cost carbon electrodes with mouth guards, in order to monitor possible levels of abuse drugs in saliva. These sensors are…
Paper is a low-cost, affordable and disposable platform that has been used as a substrate for chemical sensors in recent years and its use represents an alternative for carrying out chemical analysis in regions with limited resources. The manufacture of flow injection analysis systems using paper as a substrate instead of conventional FIA apparatus is still under-explored, requiring refin…
D-Dimer (DD) is a general term to describe heterogeneous fibrin degradation products present in blood. Circulating DD values are raised in various clinical conditions although, in general, an elevated DD value indicates some type of thrombosis.It has had particular relevance on the management Pulmonary Embolism (PE). PE is a potentially acute life threating pathology of difficult diagnosi…

Additive manufacturing, known as 3D printing, is an emerging technology for developing new devices for diverse applications, especially for Analytical Chemistry. Additive manufacturing uses low-cost 3D printers, affording scalable production. Besides this feature, the freedom of creation makes 3D printing a great tool for producing miniaturized devices integrated with complex functions, s…
Among many applications regarding 3D printing in modern society, this technology has shown promising features for fabricating electroanalytical devices, such as large-scale fabrication and fast prototyping of an infinite array of possibilities, from cells to sensors, using inexpensive polymeric materials conductive filaments. The option of printing an entire electrochemical system represe…
Wearable electrochemical sensors have become increasingly attractive due to non-invasive biomarkers detection direct on-body to monitor health risk, performance, and nutrition markers. In this perspective, the development of simple, low-cost, high-sensible, and flexible electrochemical devices has attracted significant attention. The use of polymeric substrates to fabricate these electroc…
