“…Coatings are then introduced into a fixed concentration of bacteria and are incubated in bacteria suspensions for 5 h. The number of colony forming units (CFUs) was evaluated according to the well‐known bacteria counting method . The efficiency of the GPTMS coatings to inhibit the bacterial adhesion (Figure ) were investigated against Gram‐negative bacteria ( E. coli ) and Gram‐positive bacteria ( S. aureus ) in comparison with the native stainless‐steel substrates.…”

Photoinitiating systems combining 2,6‐diaminoanthraquinone (AQD), iodonium salt (Iod), and benzyl alcohol derivatives have been developed to efficiently initiate the cationic polymerization of epoxy monomers upon light exposure. Electron spin resonance spin‐trapping (ESR ST) experiments, fluorescence investigations, and steady‐state photolysis have demonstrated that a dye‐sensitized reaction occurs between AQD and the benzyl alcohol derivatives through a hydrogen abstraction mechanism upon light illumination, followed by reduction of Iod. The in situ liberation of protic acids promotes the cationic photopolymerization of epoxy monomers concomitantly with hydrolysis and condensation of the reactive methoxysilanes of an organic–inorganic precursor, for example, 3‐glycidyloxypropyltrimethoxysilane (GPTMS). Nanoindentation experiments and scratch resistance tests proved that the resulting GPTMS coatings exhibit very good resistance to brittle fracture and excellent adherence to stainless‐steel substrates. Interestingly, antibacterial tests of the GPTMS coatings showed efficient antifouling and biocide properties against E. coli and S. aureus.

“…Another significant example of a photosensitive substance intended for oral administration is quercetin-the naturally occurring flavonoid with several relevant properties, such as anti-allergic, anti-inflammatory, anticancer and anti-viral activity [194]. According to Pangeni et al [176], quercetin-loaded nanoemulsion, obtained by titration of aqueous phase can be a promising formulation for obesity treatment.…”

Recent Advances in the Structural Design of Photosensitive Agent Formulations Using “Soft” Colloidal Nanocarriers

et al. 2020

The growing demand for effective delivery of photosensitive active compounds has resulted in the development of colloid chemistry and nanotechnology. Recently, many kinds of novel formulations with outstanding pharmaceutical potential have been investigated with an expansion in the design of a wide variety of “soft” nanostructures such as simple or multiple (double) nanoemulsions and lipid formulations. The latter can then be distinguished into vesicular, including liposomes and “smart” vesicles such as transferosomes, niosomes and ethosomes, and non-vesicular nanosystems with solid lipid nanoparticles and nanostructured lipid carriers. Encapsulation of photosensitive agents such as drugs, dyes, photosensitizers or antioxidants can be specifically formulated by the self-assembly of phospholipids or other amphiphilic compounds. They are intended to match unique pharmaceutic and cosmetic requirements and to improve their delivery to the target site via the most common, i.e., transdermal, intravenous or oral administration routes. Numerous surface modifications and functionalization of the nanostructures allow increasing their effectiveness and, consequently, may contribute to the treatment of many diseases, primarily cancer. An increasing article number is evidencing significant advances in applications of the different classes of the photosensitive agents incorporated in the ”soft” colloidal nanocarriers that deserved to be highlighted in the present review.

“…On one hand, passive materials, which prevents bacterial adhesion and can be obtained by the use of poly(ethylene glycol) [6], polysaccharides [7], N-acetylpiperazine or fluorinated compounds [8,9]. On the other hand, active or biocide materials can be prepared via the incorporation of metal nanoparticles which are well-known for their antibacterial activities, such as silver [10] and copper [11], by using polymers having ammonium or sulfonium salts [12] and organic compounds such as N-halamines [13], phenols [14,15] and aromatic acids [16,17]. Essential oils constitute a source of terpenes that are natural molecules, which are known as antibacterial and antimicrobial compounds [18][19][20][21][22].…”

Co-Networks Poly(hydroxyalkanoates)-Terpenes to Enhance Antibacterial Properties

et al. 2020

Biocompatible and biodegradable bacterial polyesters, poly(hydroxyalkanoates) (PHAs), were combined with linalool, a well-known monoterpene, extracted from spice plants to design novel antibacterial materials. Their chemical association by a photo-induced thiol-ene reaction provided materials having both high mechanical resistance and flexibility. The influence of the nature of the crosslinking agent and the weight ratio of linalool on the thermo-mechanical performances were carefully evaluated. The elongation at break increases from 7% for the native PHA to 40% for PHA–linalool co-networks using a tetrafunctional cross-linking agent. The materials highlighted tremendous anti-adherence properties against Escherichia coli and Staphylococcus aureus by increasing linalool ratios. A significant decrease in antibacterial adhesion of 63% and 82% was observed for E. coli and S. aureus, respectively.
