The excitation of plasmon-polariton modes on the surface of metallic nanoparticles (NPs) enables a variety of applications for these materials, such as photocatalysts and photovoltaic and sensing devices. Plasmon excitation in NPs implies an increase in the intensity of spectroscopic signals from adsorbed molecules, in particular, the enhancement of Raman spectra (surface-enhanced Raman s…
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…
Ionic liquids are by definition salts with melting points lower than 100ºC. The growing interest in such materials comes from the fact that these liquids are potential substitutes of conventional organic solvents in several processes. It is explained essentially to properties as high chemical and thermal stability, wide electrochemical window, and the extremely low vapor pressure, that av…
The substitution of conventional organic solvents by room temperature ionic liquids (RTIL) has shown potential applications in the capture and storage of CO2. This is a consequence of their high solvent capacity, high chemical and thermal stability, and their negligible vapour pressure, that minimizes evaporation losses. The current increasing of scientific papers and patents related to i…
The detection of molecules at extremely low concentrations is a fundamental challenge in fields such as analytical chemistry, biomedicine, food safety, and environmental monitoring. In this context, Surface-Enhanced Raman Spectroscopy (SERS) has emerged as a powerful technique due to its ability to detect molecules at trace levels with high specificity and sensitivity. The SERS effect occ…
In the environment, microplastics frequently act as chemical vectors, transporting several toxic compounds adsorbed on their surface. Such aspect of microplastic pollution evidences the complexity of this pollutant, demanding new analytical approaches for its monitoring. The present project aims to develop an efficient methodology for detecting emerging contaminants adsorbed on the surfac…
The enhancement of surface-enhanced Raman scattering (SERS) is generally attributed to contributions from two distinct mechanisms, the electromagnetic (EM) and the chemical effect (CE). The EM contribution, the main factor responsible for the enhancement, is well known and described, since it depends essentially on the plasmonic properties of the nanoparticle. Although the CE contribution…

The microplastic widespread pollution is raising and growing concerns about its harmful effects on livingorganisms. The establishment of the hazard associated with the occurrence of this pollutant in the environmentcan only be properly carried out if based on multi and interdisciplinary data, with an abundance survey andclassification of physical characteristics and on the chemical compos…
The development of new luminescent materials that present synergism with high charge mobility and emission efficiency is relevant for advancing new technologies to produce efficient optoelectronic devices. This proposal intends to develop organic light-emitting devices (OLEDs), exploring the photoluminescence and electroluminescent properties of the lanthanide (Ln3+) complexes. In this ve…
The development of pesticides was fundamental to increasing food production. However, their deliberate use on a global scale has caused several harmful effects due to the contamination of ecosystems, becoming an environmental and public health problem. In this sense, different methodologies have been developed to detect trace amounts of these compounds or their degradation products. A qui…

This project addresses the research internship at the Organic Electroactive Materials (OEM) group at the Department of Physics at Durham University in UK, through the BEPE/FAPESP Postdoctoral program for 12 months. This proposal intends to develop organic light-emitting devices (OLEDs), exploring the photoluminescence (PL) and electroluminescent (EL) properties of the organic ligands and …
The physicochemical properties of nanoplastics (< 100 nm), coupled with their environmental abundance, present one of the most pressing challenges of current days. Compared with meso- and microplastics, nanoplastics exhibit enhanced bioavailability, potentially increasing ecological and human risks. To comprehend their transport dynamics, interaction and sorption of contaminants, environm…
Metallic nanoparticles with plasmonic characteristics constitute a class of materials with interesting properties, such as the effect of enhancing the Raman signal (Surface Enhanced Raman Scattering), photocatalytic capacities of improving the kinetics of redox reactions and unique optical properties related to the surface plasmon.
