“…The release of copper ions from the surface of the NPs, as well as the production ability of different ROSs such as O − 2 , HO 2 , OH, and H 2 O 2 causes to death of bacteria within water (Hassan et al, 2012). There have been reported similar results on the antimicrobial effect of synthesized CuO-NPs on different substrates, for example, polyvinyl alcohol (Chowdhury, Beg, Khan, & Mina, 2013), cotton fibers (Subramanian, AnuPriya, ThankaRajan, Dhandapani, & Jayachandran, 2014), silica film (Akhavan & Ghaderi, 2010), zeolite (Alswat, Bin Ahmad, Hussein, Ibrahim, & Saleh, 2017), and copper layer (Ekthammathat, Thongtem, & Thongtem, 2013). Figure 4c shows the plate cultures containing cultured bacteria from the contaminated water at different time intervals.…”

The aim of this research was synthesizing of bacterial cellulose (BC) nanohybrids by incorporation of CuO‐NPs and evaluation of their ability in the removing of microbial, heavy metals, and dyes pollutants from water. CuO‐BC nanohybrids were synthesized by two in situ (sonochemical and precipitation) methods and compared with ex situ synthesized nanohybrid. FE‐SEM images revealed that the growth of CuO‐NPs in the sonochemically synthesized in situ substrate is better. The ex situ nanohybrid had the highest loading capacity (27.17 μg/cm2) but the migration of CuO‐NPs from this substrate was higher than in situ ones. According to antimicrobial tests, 80% and 90% of initial population of E. coli and S. aureus, respectively, were removed after 6 hr contact of substrates with water. The potential of the substrates in the adsorption of lead and arsenic was about 60% after 24 hr. About 75% of methylene blue and methyl orange dyes were adsorbed into substrates after 6 hr. CuO doped substrates had the photocatalytic activity and caused to decrease the oxygen content about 4%–7% during 6 hr. In general, the reusability of ex situ synthesized substrate was lower than in situ nanohybrids. Sonochemically synthesized substrate was suggested as the best nanohybrid for water purification applications in terms of morphological properties and reusability. Practitioner points CuO‐BC nanohybrids were prepared by in‐situ and ex‐situ methods. Well distribution of NPs and slower release was achieved by in‐situ methods. Antimicrobial and photocatalytic activity of ex‐situ nanohybrid was higher than in‐situ ones. Dyes and heavy metals were removed successfully with nanohybrid substrates. Sonochemical in‐situ nanohybrid exhibited the best water purification performance.

“…Advance nanocomposites or nanomaterial modified compounds have got huge attention in the past few years due to its remarkable properties and applications. Some examples are zeolite/zinc oxide-copper oxide nanocomposite, copper oxide loaded zeolite nanoparticles, pseudobactins bounded iron nanoparticles for extraordinary antibacterial properties [44][45][46]. Few others are, silica/carbon nanotubes and silica activated carbon, bimetallic nanoparticles loaded on activated carbon, etc for water and petroleum product purifications [47][48][49][50][51].…”

Zinc oxide nanoparticles (ZnO-NPs) were synthesized and decorated simultaneously onto the glass fiber pre-filter paper (GF paper) by the sonochemical method without using any additional reagents (a 'Green' synthesis approach). ZnO-NPs decorated GF paper was characterized by electron, confocal laser scanning and atomic force microscopy, fourier transform infrared and atomic emission spectroscopy, X-ray diffraction, and thermogravimetric analysis etc. Due to the massive void volume space, exceptional dimensional stability, large thickness (790 μm) of the GF paper (unlike other paper materials) and ultrasonic irradiation effects, ZnO-NPs were decorated in the enormous amount (96 mg per paper) without causing any adverse effects on the GF paper. Such a huge amount decoration onto GF paper makes it multifunctional, fluorescencet (orange-pink color, 535-624 nm) under ultra-violet light (360 nm) and antibacterial. The antibacterial activity of the ZnO-NPs decorated GF paper was examined against Gram-positive bacteria Bacillus subtilis 168 and Staphylococcus aureus (MCC 2043, pathogenic). The outcomes from the antibacterial experiments revealed ∼99% (2 log) reduction in the survival of the filtered bacteria (B. subtilis) on the ZnO-NPs decorated GF paper due to the toxicity of ZnO-NPs on bacterial cells like cell shrinkage, cytoplasmic leakage, cell burst, etc. Multifunctional, ZnO-NPs decorated GF paper could be used for fluorescencet and antibacterial paper-based applications.techniques are its expensiveness, inefficient in throughout three dimensional (3D) coating, requirement of extra reagents etc [15]. Thus, appropriate paper material as well as coating technique is required to fabricate costeffective and novel multifunctional paper. To the best of our information, fewer reports are available on glass filter papers. Through this study we have tried to explore the properties and possible applications of existing glass fiber pre-filter paper (GF paper) through decoration with the zinc oxide nanoparticles (ZnO-NPs). GF paper is made up of borosilicate microfibers, silica (SiO 2 ) as a main component and some quantity of boron oxide (B 2 O 3 ), aluminium oxide (Al 2 O 3 ), sodium oxide (Na 2 O) and potassium oxide (K 2 O) [17]. Glass fibers have some exceptional properties which make them very different from natural fibers such as excellent strength, heat and chemical resistant but not to strongly alkaline and acidic (hydrofluoric acid) environment [17]. Fibers of the GF paper are thinner in diameter (100 nm to several μm) and uniform in contrast to the fibers of the other papers because of which GF paper have massive void volume space and large surface area [17]. Thickness of the GF paper is large (790 μm), so all these properties make it appropriate for filtering heavily contaminated liquids. Resin bonded and unbounded GF papers are available for the wide application in the filtration technique. Acrylic resin-bonded GF papers have more rigidity, dimensional stability and strength in comparison to the unbounded one as ...

“…80 Silver (Ag) has been highlighted among other inorganic metals due to introducing the most well-established antibacterial properties. To guarantee the long-term antibacterial activity of Ag NPs, they were incorporated to zeolite media, 79,[81][82][83][84][85][86][87][88][89][90] as zeolite particles could hold silver ions and protect their bacteriostatic properties which lie on their ion-exchangeable sites, and this depends on composition of the selected zeolite, eg, A zeolite, X zeolite, Y zeolite, etc. 30 Based on a research by Dong et al on the antibacterial properties of Ag-containing nanozeolites, E. coli cells were immediately destroyed upon exposure to water forms of ultra-small EMT-type zeolite containing Ag0 or Ag+ ion.…”

The advent of porous materials, in particular zeolitic nanoparticles, has opened up unprecedented putative research avenues in nanomedicine. Zeolites with intracrystal mesopores are low framework density aluminosilicates possessing a regular porous structure along with intricate channels. Their unique physiochemical as well as physiological parameters necessitate a comprehensive overview on their classifications, fabrication platforms, cellular/ macromolecular interactions, and eventually their prospective biomedical applications through illustrating the challenges and opportunities in different integrative medical and pharmaceutical fields. More particularly, an update on recent advances in zeolite-accommodated drug delivery and the prevalent challenges regarding these molecular sieves is to be presented. In conclusion, strategies to accelerate the translation of these porous materials from bench to bedside along with common overlooked physiological and pharmacological factors of zeolite nanoparticles are discussed and debated. Furthermore, for zeolite nanoparticles, it is a matter of crucial importance, in terms of biosafety and nanotoxicology, to appreciate the zeolite-bio interface once the zeolite nanoparticles are exposed to the biomacromolecules in biological media. We specifically shed light on interactions of zeolite nanoparticles with fibrinogen and amyloid beta which had been comprehensively investigated in our recent reports. Given the significance of zeolite nanoparticles' interactions with serum or interstitial proteins conferring them new biological identity, the preliminary approaches for deeper understanding of administration, distribution, metabolism and excretion of zeolite nanoparticles are elucidated.
