“…Also, an S. aureus MRSA growth increase on the silicone-coated monolith (SilM) was observed. This behaviour was also found by others [20,21], particularly on functionalised silicone-or polydimethylsiloxane (PDMS)-based coated surfaces. It can be associated with damages on the major PDMS-based coatings original properties (e.g.…”

Water bio-contamination causes serious environmental and economic penalties and health risks in several applications (e.g., freshwater and seawater circuits). In this work, a nontoxic potential strategy able to control this bioburden through new functional bioactive agents, capable of being tethered in polymeric coatings, is presented. Econea biocide was successfully tethered in a silicone-based coating, further used to coat polymeric substrates and monolithic filters. Coated substrates demonstrated promising antifouling effects after being submerged for more than a year in simulated and real conditions. Furthermore, coated monolithic filters showed auspicious growth inhibition and bacteriostatic behaviour for the S. aureus MRSA bacteria.

“…293,[307][308][309][310][311][312] Nitroxides are known to protect cells against 293,308,315 The ability of nitroxides to participate in all of the above pathways relies on redox transformations between three oxidation states -the nitroxide, hydroxylamine and oxoammonium derivatives. Scheme 3 shows the oxidation states of 4-hydroxy-2,2,6,6-tetramethyl-1-piperidinoxyl (38), one of the most widely studied nitroxides in the literature.…”

“…In this context LIF can provide a valuable characterization tool, as fluorescence can highlight many constituent materials simultaneously, and may also yield data useful to detect early signs of biological attack (Raimondi et al, 2007;Caneve et al, 2010;Wojtanowski et al, 2015 ). This is an interesting application because of the susceptibility of modern and contemporary materials to (Cappitelli & Sorlini, 2008;Shashoua, 2008). On the other hand the cited range of materials employed and their frequent co-presence make the interpretation of data acquired with LIF particularly challenging.…”

Laser-induced fluorescence (LIF) has found, in the recent years, widespread application to the field of material study and characterization. In particular, LIF has been applied to the assessment of damage, biological growth, and the analysis of specific materials on various surfaces in cultural heritages. Only a few papers deal with the application of LIF to the study of modern synthetic materials (mostly plastics) and pigments, and the analysis of contemporary works of art. Preliminary laboratory measurements on a wide range of plastic and cellulose-based materials, solvents, resins, and varnishes have been performed for rapid material characterization during in situ measurement campaigns in cultural heritage, security, and forensic contexts. Four paintings by Gastone Novelli, in the National Gallery of Modern and Contemporary Art, Rome, have been investigated by a compact LIDAR fluorosensor scanning system developed at the Laboratory of Diagnostic and Metrology in the ENEA Centre of Frascati (UTAPRAD-DIM Laboratory) for LIF measurements. Results and the relative data processing have provided fluorescence images, false color images, and punctual spectral information. The comparison with data and spectra from purpose-built reference databases has enabled recognition of materials on the paintings, and provided information on their production.
