Plasmonic Au@Ag@mSiO2 Nanorattles for In Situ Imaging of Bacterial Metabolism by Surface-Enhanced Raman Scattering Spectroscopy
<p>Related publication: De Marchi, S; García-Lojo, D; Bodelón, G; Pérez-Juste, J; Pastoriza-Santos, I. Plasmonic Au@Ag@mSiO<sub>2</sub> Nanorattles for In Situ Imaging of Bacterial Metabolism by Surface-Enhanced Raman Scattering Spectroscopy. <em>ACS Applied Materials & Interfaces</em> 2021. <a href="http://doi.org/10.1021/acsami.1c21812">DOI: 10.1021/acsami.1c21812</a>.</p> <p> </p> <p>Abstract:</p> <p>It is well known that microbial populations and their interactions are largely influenced by their secreted metabolites. Noninvasive and spatiotemporal monitoring and imaging of such extracellular metabolic byproducts can be correlated with biological phenotypes of interest and provide new insights into the structure and development of microbial communities. Herein, we report a surface-enhanced Raman scattering (SERS) hybrid substrate consisting of plasmonic Au@Ag@mSiO<sub>2</sub> nanorattles for optophysiological monitoring of extracellular metabolism in microbial populations. A key element of the SERS substrate is the mesoporous silica shell encapsulating single plasmonic nanoparticles, which furnishes colloidal stability and molecular sieving capabilities to the engineered nanostructures, thereby realizing robust, sensitive, and reliable measurements. The reported SERS-based approach may be used as a powerful tool for deciphering the role of extracellular metabolites and physicochemical factors in microbial community dynamics and interactions.</p>

Analysis of heritage stones and model wall paintings by pulsed laser excitation of Raman, laser-induced fluorescence and laser-induced breakdown spectroscopy signals with a hybrid system
<p>Laser based analysis of artworks benefits from the development of hybrid instruments where a single laser source serves to excite fluorescence, Raman and laser induced breakdown spectroscopy (LIBS) signals. Laser induced fluorescence (LIF) and Raman spectra provide information at the molecular level, while LIBS serves for identifying the elemental composition of the substrate under consideration. Studies using several excitation wavelengths on different types of materials and substrates help to develop and establish these hybrid systems for the conservation of artworks.</p>
