M.A.Cotta graduated (B.Sc. in Physics,1984), with M.Sc. (1987) and Ph.D. (1991) in Physics, at the University of Campinas. She worked as a postdoctoral fellow at AT & T Bell Laboratories (Murray Hill, USA, 1991-1993). She is currently full professor (MS6), at the Gleb Wataghin Institute of Physics, University of Campinas. She is also a member of the Brazilian Materials Research Society scientific board (2016-2018) and associate editor of the journal ACS Applied Nano Materials. Her research projects explore the areas of Materials Science and Biological Physics, with focus on the study of advanced semiconductor nanomaterials, from synthesis to biosensor fabrication, as well as applications of optical, electron and scanning probe microscopy to basic investigations on biomaterials and biological systems.

- III-V semiconductor nanowires as new tools for biology investigations, BP.PD
Abstract
In this project, we intend to study the synthesis of III-V semiconductor nanowires, with the overall goal of their application in biological physics studies. In particular, we intend to explore the growth of (In)GaP nanowires, studying the transition between dominant crystallographic phases (cubic and hexagonal) to create structures with emission in the visible spectral range. The inclu...
- P-N junctions in III-V semiconductor nanowires: a platform for applied studies, BP.DR
Abstract
III-V semiconductor nanowires have shown potential for applications in many areas from optoelectronics to biosensing. In this project, we intend to study the growth of III-V semiconductor nanowires doped in situ to obtain P-N junctions (axial and/or radial) forming arrays, which will serve as platforms for applied studies. Our goal is, first, to contribute to the discussion in the liter...

Abstract
An important line of research in bioactive materials aims specifically at obtaining coatings that provide antimicrobial resistant surfaces which are also non-toxic, biodegradable and suitable for contact with food or humans. This project intends to study the adhesion behavior of Pseudomonas aeruginosa and Staphylococcus aureus on the different types of nanostructured films based on ch...
- Development of biosensors based on semiconductor nanowires and applications to adhesion studies on Xylella fastidiosa, BP.PD
Abstract
In this project, we intend to integrate the research carried out in two different areas to create a platform for integration in nanobiotechnology. First, the historically most active research area from our group, semiconductor growth, is now directed to the synthesis of group III-V semiconductor nanowires. The second area refers to a more general problem in biology, the formation of bac...
- Semiconductor nanowires: investigation of formation processes and applications in thermoelectric systems, BP.DR
Abstract
Semiconductor nanowires have been widely investigated in the last decade due to possible applications associated with their geometry and physical properties. However, some issues related to the growth of nanowires, particularly those of III-V compounds, remain to be answered so that technological applications of these nano-objects can be accomplished. In this project we intend to study ...

Published in October 20, 2016 - Pesquisa FAPESP. Physicists and biologists investigate how Xylella fastidiosa bacteria assemble into biofilms. In the video produced by Pesquisa Fapesp, physicists Mônica Cotta and Carlos Lenz Cesar from the University of Campinas (Unicamp), and biologist Alessandra de Souza, researcher at the Sylvio Moreira Citriculture Center of the Campinas Institute of Agronomy (IAC), revisit the collaborative process leading to the description of this biofilm. The disease it causes endangers plants of economic importance, such as orange and olive trees.(References retrieved automatically from Web of Science and SciELO through information on FAPESP grants and their corresponding numbers as mentioned in the publications by the authors)
