“…The ζ value for the AgNPs produced in this study indicated good stability of the colloid, which could be attributed to the presence of MPs that functionalized the AgNPs. The solution had the highest negative value of the Zeta potential (−38.17 mV), and so was the most stable because the repulsive forces between negatively charged particles prevent agglomeration [ 64 , 65 ].…”

Today, the overall occurrence of re-emerging and rising illnesses has been a serious load on economies as well as public health. Here, we describe a simple, nontoxic and eco-friendly method for the synthesis of milk protein (MP)-stabilized silver nanoparticles (MP-s-AgNPs) using ultrahigh-temperature full cream milk. Highly stable AgNPs were prepared with a fair control over their size, without using any reducing or stabilizing agent, and their formation was attributed to the presence of the MP casein. Ag+ ion reduction was possibly caused by the MPs. The synthesized MP-s-AgNPs were characterized in detail by ultraviolet-visible spectroscopy, Fourier-transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, transmission electron microscopy and dynamic light scattering. MP-s-AgNPs showed inhibitory activity against both Gram-positive (Bacillus subtilis and Staphylococcus aureus) and Gram-negative microorganisms (Salmonella typhi and Escherichia coli). Moreover, MP-s-AgNPs were found to be more toxic to bacteria than to fungi (Aspergillus fumigatus, Aspergillus ochraceus and Penicillium chrysogenum).

“…Acknowledgements The authors (SSR and AOCI) would like to thank the Council for Scientific and Industrial Research (HGER74p) Scheme 2 As demonstrated in the study of Pandey et al [104], the κ-CG-s-AgNPs nanocatalyst exhibited exceptional degradation characteristics in the reduction of organic dyes (MB and RhD B). It was argued that the decolourization of the dyes occurred faster than their mineralization.…”

“…They claimed that their approach was not only green but also eco-friendly and sustainable, because this catalyst was recyclable and reusable many times without losing its efficiency, affording both economic and environmental benefits. They further showed that the fabricated κ-CG-s-AgNPs catalytic agent demonstrated an exceptional degradation activity, under visible light, toward the organic dyes Rhodamine B (RhD B) and methylene blue (MB), as shown in Scheme 2 [104].…”

“…In a related study, Pandey et al [104], demonstrated that a k-carrageenan gum-stabilized silver nanoparticles (AgNPs) nanocatalyst (κ-CG-s-AgNPs), fabricated using a green methodological approach, exhibited an improved and highly efficient catalytic degradation of dyes in industrial wastewater. They claimed that their approach was not only green but also eco-friendly and sustainable, because this catalyst was recyclable and reusable many times without losing its efficiency, affording both economic and environmental benefits.…”

Polymer-Based Membranes and Composites for Safe, Potable, and Usable Water: A Survey of Recent Advances

In the past decades, the demand for potable and usable water has been on a continual increase, while its availability has been on an exponential decline. Studies have argued that, by 2050, only a small fraction of the world's population will have access to clean and safe water, thereby exposing a significant portion of the population to a serious water crisis. Large volumes of wastewater are generated yearly, both domestically and industrially, and the necessity to develop effective and efficient strategies and technologies to recover these wastewaters and turn them into safe and reusable waters is a momentous concern among scientists and policymakers. Across the globe, governments are developing approaches and strategies to mitigate both short-and long-term water challenges resulting from various anthropogenic activities that have contributed to the rising degradation of water quality, coupled with the attendant negative impact of natural disasters, increasing urbanization, among others. Notwithstanding, the advancements in nanotechnology have made it possible to engineer novel and innovative polymer-based materials and composites that possess desirable and even predictable properties for targeted applications, which has presented the opportunity for the development of cost-effective nanotechnologies and processes employed in water remediation, reclamation, purification, and treatment processes worldwide. Nevertheless, these innovative technologies and processes have also been shown to have their limitations and challenges in the enhancement of water quality. Herein we survey the current advancement of selected polymer-based membranes and composites and their intervention for the production of safe, potable, and usable water, as well as their limitations, challenges, recommendations, and future perspectives.
