Sara Fateixa, Helena Nogueira e Tito Trindade are the authors of the review article on nanostructures applied in surface-enhanced Raman scattering (SERS)
Researchers and teachers from CICECO and Chemistry Department of the University of Aveiro (UA) published an article that illustrates the cover of the prestigious journal Physical Chemistry Chemical Physics (PCCP) of the Royal Society of Chemistry. The article "Hybrid nanostructures for SERS: materials development and chemical detection" written by Sara Fateixa, Helena Nogueira e Tito Trindade, provides a critical review on hybrid nanomaterials used as substrates in surface-enhanced Raman scattering (SERS).
Are considered various nanostructures composed by at least two different materials, in which at least one is SERS active metal (e.g. gold or silver), that can be used as platforms for (bio) chemistry detection. "It is a job that aspired to go beyond description and critical review of the state of the art in terms of development of nanomaterials for SERS," the researchers suggest.
Thus, say the researchers, "the reader is faced with a unique perspective on the integration of two major areas of research in Nanosciences and Nanotechnology: plasmonic nanostructures and the chemistry of hybrid nanomaterials."
Simultaneously, the article puts in perspective future applications of Raman spectroscopy (SERS), particularly in new protocols of chemical analysis and biodetection. This work meets with recent developments in this area, particularly in terms of new techniques for detection of analytes present in trace amounts, such as some compounds of biomedical and environmental interest.
It is foreseen that parallel to the strand of material development, the development is accentuated in the instrumentation support for this type of studies, not only by the production of more sophisticated instruments but also by the easier integration into extended analysis contexts.
Effectively, they explain, "the cover results in an image of a silver nanocomposite and polymer obtained by using a new equipment which integrate a confocal Raman microscope / AFM". It is a scientific equipment recently acquired by CICECO and which is installed in the laboratory of vibrational spectroscopy of the Department of Chemistry-CICECO.
This review work includes over 500 references listed and was considered "hot article" by PCCP journal and can be found here.
