“…The WI is not affected by treatment with WPU as was observed for all finished fabrics due to the surface plasmon resonance on the TiO 2 @ Ag NPs surface. 20 The TiO 2 @Ag/WPU finishing solutions can improve the mechanical properties of PET fabrics in comparison to S0 and SW samples. It is suggested that both TiO 2 @Ag and WPU contents had a slight effect on the tensile properties of the finished fabrics.…”

The sudden outburst of Coronavirus disease 19 or COVID-19 has raised serious awareness about viral contamination on the environment, which is one of the major causes of the disease. Transmission via contaminated surfaces has been recognized as a significant route for spreading the virus. To suppress and control the spread of SARS-CoV-2, potent virucidal finishing agents for decontamination of medical textiles are urgently required. In this study, an environmental-friendly, economical, non-toxic, and practical finishing on medical textiles with potent virucidal activity was proposed with the combined concepts of a new green synthesis of TiO2@Ag core-shell nanostructures using ascorbic acid reduction and UV-curing process. In order to evaluate efficiency of virucidal activity, effects of the amount of TiO2@Ag NPs and contact time were determined against the coronavirus following ISO 18184:2019 standard. The finishing agent exhibited an excellent 99.9% virucidal efficacy. The stability of virucidal activity and mechanical properties were determined under repeated washing. The finished fabrics had the ability to retain their virucidal activity and tensile strength through 20 washes. The results suggested that the finishing agent had great potential as a potent and non-toxic virucide against the coronavirus for medical textile applications.

“…Research has shown that titanium oxide (TiO 2 ) is an effective material for the photodegradation of organic pollutants in water, it is inexpensive, nontoxic, photosensitive, and environmentally friendly. Nevertheless, TiO 2 based photocatalytic methods have lower photocatalytic activity, which reduces the range and reproducibility of the determination of COD [ 88 ]. Therefore, Liang et al., modified a TiO 2 nanotube array by gold nanoparticles (AuNPs) to improve the sensitivity, stability, and lifetime of the sensor.…”

The survival of living beings, including humanity, depends on a continuous supply of clean water. However, due to the development of industry, agriculture, and population growth, an increasing number of wastewaters is discarded, and the negative effects of such actions are clear. The first step in solving this situation is the collection and monitoring of pollutants in water bodies to subsequently facilitate their treatment. Nonetheless, traditional sensing techniques are typically laboratory‐based, leading to potential diminishment in analysis quality. In this paper, the most recent developments in micro‐ and nano‐electrochemical devices for pollutant detection in wastewater are reviewed. The devices reviewed are based on a variety of electrodes and the sensing of three different categories of pollutants: nutrients and phenolic compounds, heavy metals, and organic matter. From these electrodes, Cu, Co, and Bi showed promise as versatile materials to detect a grand variety of contaminants. Also, the most commonly used material is glassy carbon, present in the detection of all reviewed analytes.

Polyurethane (PU) is a well-known synthetic polymer consisting of isocyanates, polyols, and chain extenders. The incorporation of fillers into the PU polymeric matrix, including inorganic nanomaterials, synthetic polymers, natural components, quaternary ammonium salts, and commercial drugs, bestows the endproducts with unique and improved physicochemical properties. Fillers can be used to tailor the molecular orientation, crystallinity, cross-linking, and functional chemical groups of PU-based composites. The bactericidal ability of PU composites highly depends on their surface composition, morphology, charge, and stability. Recent advancements highlight the potential of PU composites in combating bacterial infections. In this review, the cutting-edge of inorganic and organicbased PU composites for antibacterial applications is addressed. Notably, selective examples of scientific reports' key findings and their crucial information on PU composites are discussed. Furthermore, the positive impact of PU composites on the future prospects of this field is explored. This review comprehensively deliberates the values of PU composites towards practical applications in the biomedical field of antibacterial activity. This review can help researchers to gain widespread knowledge and a better understanding of PU composites for antibacterial applications.
