Their structure\u2013function relationship was evaluated by studying their radical-generation and radical-stabilization activities, using electron paramagnetic resonance spectroscopy in tandem with their biocide activity toward marine bacteria\u00a0Aliivibrio fischeri. The surface properties of the C\u2013SiO<sub>2<\/sub>\u00a0hybrids were studied by Raman spectroscopy and surface-charge analysis by zeta potential measurements. Raman spectroscopy indicates that the FSP process, as designed and used herein, allows the progressive incorporation of nanocarbon moieties into the SiO<sub>2<\/sub>\u00a0nanostructure, which may lead to distortion of the siloxane matrix. Concurrently, the C\u2013SiO<sub>2<\/sub>\u00a0hybrids\u2019 surface charge profile reveals a trend correlated with the acute biocide activity toward\u00a0Aliiv. fischeri. Interestingly, we find no correlation between the stable radical population and the nanohybrids\u2019 biocide activity. Within this context, we discuss the role of surface charge, radical properties, and SiO<sub>2<\/sub>\u00a0lattice distortions by the nanocarbon, all of them parametrized\u00a0via\u00a0FSP process protocols. Thus, the present study\u2019s findings provide critical insight into the structure\u2013biocide activity relationship of carbon\u2013SiO<sub>2<\/sub>\u00a0hybrid nanoparticles. Technology-wise, the present work exemplifies a scalable FSP process for the industrial production of applied nanomaterials, such as C\u2013SiO<sub>2<\/sub>\u00a0nanostructures.<\/em><\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>SiO<sub>2<\/sub>; \u039danocarbon; Nanohybrids; Flame Spray Pyrolysis; Nanotoxicity; Aliivibrio fischeri; EPR Spectroscopy; Biocide Activity<\/p>\n<!-- \/wp:paragraph -->","protected":false},"excerpt":{"rendered":"<p>Fotini Fragou Areti ZindrouYiannis Deligiannakis, Maria Louloudi.
