Residency period: April 4, 2022 and April 3, 2023
IEAT resident, Gilberto Medeiros Ribeiro has been working in the areas of nanoscience, materials and applications in computer architecture for the last 25 years. In particular, his main interests cover the field of information sciences from the point of view of physical implementation and how one can store, transmit and compute information using nanostructures and new materials. For his IEAT residency program, he focuses primarily on the development of microwave microscopy applied to living cells and the role of glucose in contrast. This effort brings together professors of Computer Science, Electrical Engineering, Biology, Physics, Chemistry and Medicine, aiming to fill gaps in microwave imaging, particularly in issues of resolution and contrast. He graduated in Electrical Engineering from UFMG, followed by a PhD in Physics/Materials Science at UFMG with a research stay at UC Santa Bárbara. After finishing his PhD, he joined Hewlett-Packard Laboratories in Palo Alto, CA. After spending three years in Palo Alto, he worked at the Synchrotron Lab in Campinas as a researcher in the scanning probe microscopy laboratory, research manager at Hewlett-Packard Labs and, more recently, at CEITEC in Porto Alegre before joining UFMG as a professor holder in Physics. He has more than 170 articles published in scientific journals, 47 patents granted at the USPTO, and more than 50 patent applications pending worldwide. He is currently director of the Coordination of Transfer and Technological Innovation at UFMG.
NANO-BIO CONNECTION: AN EFFORT SUPPORTED BY INSTRUMENTATION AND ARTIFICIAL INTELLIGENCE
The motivation for the proposed research is the subsequent step of an initiative such as the SPM Brasil network, leveraging the knowledge obtained in instrumentation, more specifically promoting the integration of nanotechnology and machine learning aspects in the analysis of biological systems. Two key points were chosen to carry out this approach: i) near-field microwave microscopy, or scanning Microwave Impedance Microscopy (sMIM) and ii) fabrication of substrates for Surface Enhanced Raman Spectroscopy (SERS). The expected results involve: i) development and application of microwaves for imaging biological systems, and possibly as a diagnosis of the concentration of certain polar molecules in tissues; ii) SERS diagnostic techniques for molecules and pathogens.
