Marcia L. A. Temperini obtained her Bachelor degree in Chemistry at the University of São Paulo (1971), Master?s degree (Physical-Chemistry) at the University of São Paulo (1974) and Ph.D. (Physical-Chemistry) at the University of São Paulo (1977). Currently she is full professor at the University of São Paulo. She has expertise in Chemistry with emphasis in Physical-Chemistry, acting mostly in the Vibrational Spectroscopy field. She has been using SERS spectroscopy on the understanding of the molecular adsorption processes on metallic surfaces and the behavior of Single Molecule near nanostructures. She is also interested in the spectroscopic characterization of conducting polymers, studing the morphology/structure relation. (Source: Lattes Curriculum)

The SERS effect (Surface Enhanced Raman Spectroscopy) corresponds to an enhancement of the Raman signal which can reach 10 orders of magnitude and nowadays it finds numerous applications. It is a highly sensitive vibrational spectroscopy that allows the detection of adsorbed analytes in nanostructures that support surface plasmons, such as gold nanoparticles, and combines the advantages o…
Several research activities in the Laboratório de Espectroscopia Molecular, Instituto de Química, Universidade de São Paulo, LEM/IQ-USP, are related to infrared and Raman spectroscopy. Coupling of optical microscopes to infrared and Raman spectrometers provides to vibrational spectroscopy the spatial resolution of the order of micrometer or below micrometer, then combining molecular struc…
This project describes the research activities that will be held at the Laboratório de Espectroscopia Molecular (LEM) - University of São Paulo, with direct collaboration from visiting Professor Roberto Bini from University of Florence, Italy. We have exchanged ideas with Prof. Bini who has helped us to solve experimental problems and analyze results. Professor Bini´s visit at our laborat…

The development of biological sensors for studying drug monitoring, disease detection and increased sensitivity to the dosage of these drugs are being extensively studied, however finding a substrate that is biocompatible and at the same time, efficient still remains a challenge. Polysaccharides such as alginate and chitosan are widely used for this purpose due to their low cytotoxicity, …
Lichens can be considered as symbiotic associations between a mycobionte (fungal) organism with one or more photobiont partners (algae). The polymers called glucans are the main constituents of their polysaccharide composition among several other metabolites. Glucans are polymers composed of glucose units and, in addition to being widely diffused in nature, are reported in the literature …
In this research project SERS substrates having Au nanospheres immobilized on Polyaniline (PANI) nanofibers will be prepared. The SERS effect (Surface Enhanced Raman Scattering) is the enhancement of the Raman signal of molecular species adsorbed or near the metal surface having nanoscale dimension. PANI is one of the most applied conducting polymers because of its high environmental stab…

This study is part of the post-doctoral project entitled "High pressure Raman Spectroscopy, from Aromatics amines to Conducting Polymers", FAPESP grant 2014/15107-8, which presents as the main subjects the high pressure study and reactivity of aniline and polyaniline containing gold composites (PANI-Au). High pressure research field has emerged as a new and independent research area since…
The recent scientific effort on the development of electrochemical capacitors (also known as supercapacitors) relies on the improvement of their energy densities. Ternary hybrid materials composed by carbon based-materials, conducting polymers and metal oxides have shown high performances as supercapacitors due to the complementary properties of their components. The main objective of thi…
The "Bolsa de Estágio de Pesquisa no Exterior (BEPE)" project is linked to the PhD project "Study of the structures of nanofibers of polyaniline (PANI) and their hybrids with metallic nanostructures by Raman spectroscopy", FAPESP grant 2010/18107-8. One of the topics of this project is to correlate the morphology of polyaniline with structural variations that occur due to variations in te…
