“…In addition to SO 4 ⋅ − , OH⋅ from through advanced oxidation process is able to induce the degradation of organic coatings. Consequently, the efficiencies of the degradation through other advanced oxidation processes, including UV/H 2 O 2 oxidation, Fenton reaction, and UV/Fenton reaction, which generate OH⋅ were verified (Figure S4) [35–37] . The results revealed that the efficiency of the degradation using OH⋅, was lower than that using UV‐generated SO 4 ⋅ − , indicating that the SO 4 ⋅ − is the most efficient radical for degrading organic coatings.…”

Degradation of organic coatings is essential for recycling valuable substrates. Despite the development of strategies for this purpose, the resulting degradations are typically constrained by the composition of the coating. This paper presents a simple strategy utilizing radicals induced by UV for the degradation of diverse organic coatings. The sulfate radicals, generated from UV‐exposed ammonium persulfates, induce the degradation of various organic coatings, including layer‐by‐layer assembled coating composed of alginate and chitosan polymers as well as polydopamine coating. This strategy also facilitates the separation of two adhered substrates by degrading the adhesive polymer layer positioned between them. This novel approach enables the complete degradation of various organic coatings in aqueous conditions without imposing restrictions on their composition, leading to the recovery of the original surface properties of the substrate.

“…Therefore, optimum dose selection is important. [ 52 ] When Figure 5B–D is examined, it can be observed that DFC, IBU, and PRC were removed in reaction times shorter than 30 min. DFC was almost completely removed in 20 min with 0.140 mM H 2 O 2 , IBU in 25 min with 0.105 mM H 2 O 2 , and PRC in 15 min with 0.070 mM H 2 O 2 .…”

In conventional wastewater treatment plants, micropollutants mix with the aquatic environment because they cannot be removed entirely due to their nonbiodegradable structure. Advanced oxidation processes can be considered an alternative solution to this problem. In this study, five different pharmaceutical and personal care products, carbamazepine, diclofenac, ibuprofen, paracetamol, and triclosan, which are commonly found in aquatic environments, were selected as target pollutants. The removal of these target pollutants was investigated using advanced oxidation methods such as the Fenton and UV processes (UV, UV/H2O2, and UV/TiO2). The feasibility of processes in terms of cost was investigated. In the study, both initial and final pharmaceutical concentrations were measured using liquid chromatography mass spectrometry/mass spectrometry to accurately calculate removal efficiency. It has been determined that processes other than the UV process have removal efficiency >99.9%. The UV process showed removal efficiency of 40% for carbamazepine, 90% for diclofenac, 85% for ibuprofen, 86% for paracetamol and 85% for triclosan. Among the processes with high removal efficiency, the Fenton process has been integrated into wastewater treatment plants and has been shown to be the most suitable system in terms of both performance and cost in solving the micropollutant problem.

“…Semiconductor chalcogens, such as those made of selenium, have a direct bandgap, and can be potentially used for the degradation of dyes due to their thermoconductivity, anisotropy, and high photoconductivity [ 218 , 219 , 220 , 221 , 222 , 223 , 224 , 225 , 226 , 227 ]. For instance, Ameri et al described the photocatalytic discoloration of the anionic triphenylmethane dye, bromothymol blue (BTB), using biogenic SeNPs under ultraviolet (UV) illumination (15 W) for 60 min [ 228 ].…”

Selenium is an important dietary supplement and an essential trace element incorporated into selenoproteins with growth-modulating properties and cytotoxic mechanisms of action. However, different compounds of selenium usually possess a narrow nutritional or therapeutic window with a low degree of absorption and delicate safety margins, depending on the dose and the chemical form in which they are provided to the organism. Hence, selenium nanoparticles (SeNPs) are emerging as a novel therapeutic and diagnostic platform with decreased toxicity and the capacity to enhance the biological properties of Se-based compounds. Consistent with the exciting possibilities offered by nanotechnology in the diagnosis, treatment, and prevention of diseases, SeNPs are useful tools in current biomedical research with exceptional benefits as potential therapeutics, with enhanced bioavailability, improved targeting, and effectiveness against oxidative stress and inflammation-mediated disorders. In view of the need for developing eco-friendly, inexpensive, simple, and high-throughput biomedical agents that can also ally with theranostic purposes and exhibit negligible side effects, biogenic SeNPs are receiving special attention. The present manuscript aims to be a reference in its kind by providing the readership with a thorough and comprehensive review that emphasizes the current, yet expanding, possibilities offered by biogenic SeNPs in the biomedical field and the promise they hold among selenium-derived products to, eventually, elicit future developments. First, the present review recalls the physiological importance of selenium as an oligo-element and introduces the unique biological, physicochemical, optoelectronic, and catalytic properties of Se nanomaterials. Then, it addresses the significance of nanosizing on pharmacological activity (pharmacokinetics and pharmacodynamics) and cellular interactions of SeNPs. Importantly, it discusses in detail the role of biosynthesized SeNPs as innovative theranostic agents for personalized nanomedicine-based therapies. Finally, this review explores the role of biogenic SeNPs in the ongoing context of the SARS-CoV-2 pandemic and presents key prospects in translational nanomedicine.
