“…increased as AgNO3 concentration or the photodeposition time increase, similar to the behavior reported by other authors [13][14][15]. It reveals that the low incorporation of Ag into ZnO causes a very weak excitonic band with a broad absorption in the visible region (400-550 nm), which is associated to the surface plasmon resonance in the metallic Ag NPs.…”

Surface enhanced Raman spectroscopy (SERS) is considered a versatile and multifunctional technique with the ability to detect molecules of different species at very low molar concentration. In this work, hierarchical ZnO microspheres (ZnO MSs) and Ag/ZnO MSs were fabricated and decorated by hydrothermal and photodeposition methods, respectively. For Ag deposition, precursor molar concentration (1.9 and 9.8 mM) and UV irradiation time (5, 15, and 30 min) were evaluated by SEM, TEM, X-ray diffraction and Raman spectroscopy. X-ray diffraction showed a peak at 37.9° corresponding to the (111) plane of Ag, whose intensity increases as precursor concentration and UV irradiation time increases. SEM images confirmed the formation of ZnO MSs (from 2.5 to 4.5 µm) building by radially aligned two-dimensional ZnO nanosheets with thicknesses below 30 nm. The Raman spectra of Ag/ZnO MSs exhibited a vibration mode at 486 cm−1 which can be directly associated to Ag deposition on ZnO MSs surface. The performance of SERS substrate was evaluated using rhodamine 6G. The SERS substrate grown at 9.8 mM during 30 min showed the best SERS activity and the ability to detect methylene blue at 10−9 M.

“…73 ZnO nanowires covered in Ag nanoparticles are also reported to have an antibacterial effect for cotton fabric against Staphylococcus aureus and Escherichia coli. 74 Ce-doped ZnO has antibacterial properties against Staphylococcus aureus with a rate of 83%. Against Escherichia coli, cotton fabric has better antibacterial activity when covered with ZnO without Ce doping (83%).…”

Superhydrophobic surfaces are important parts of many applications in cleaning and protective coatings. Such surfaces can be realized by controlling the surface chemistry and nanoscale structure. Elongated ZnO nanostructures, called nanowires, are often used in superhydrophobic applications due to their intrinsic characteristic advantages and simple synthesis control. This review presents a critical overview of the latest research activities focused on the ZnO nanowire superhydrophobic surfaces. A wettability mechanism background is introduced with the overlay of the crystal structure fundamentals adapted for ZnO nanowires to gain insights into the multifunction application of superhydrophobic ZnO nanowires. Moreover, the latest achievements in application of ZnO superhydrophobic nanowires or reversible wettability for self-cleaning, separation, antifogging, antibacterial, and other applications are outlined. Finally, a brief outlook on the issues and emerging perspectives of ZnO nanowire wettability research is summarized.

Hydrophilic cotton textiles, used in hospitals and sportswear, are prone to the growth of microorganisms (bacteria, fungi) resulting in hygiene and health risks. Thus, healthcare concerns have motivated the interest for the development of multifunctional antimicrobial cotton fabrics. Moreover, cotton textiles are also used in medical applications such as wound dressings. Their functionalization with anti-inflammatory agents is desirable in order to accelerate cicatrisation in the treatment of chronic wounds. This review summarizes recent advances (from January 2016 to January 2021) on the modification and coating of cotton fabrics with nanostructures (mainly metal and metal oxide nanoparticles, functionalized silica nanoparticles) to provide them antimicrobial (antibacterial and antifungal) and anti-inflammatory properties.
