“…The result showed the composite had significant antibacterial activity against both S. aureus and E. coli. Moreover, Gram-positive S. aureus seemed more sensitive than Gram-negative E. coli to the composite (Li et al 2013;Cai et al 2014). The HKUST-1/CF composite against S. aureus had (2) the preparation procedure of the HKUST-1 was the same as that of the HKUST-1/CF composite except without adding CFs (2) the preparation procedure of the CFs adsorbed Cu 2?…”

A copper-based metal-organic frameworks/cellulose fibers (HKUST-1/CF) composite was prepared by in situ and green method. Scanning electron microscopy with energy dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy and X-ray diffraction analyses revealed the functionalization of cellulose fibers (CFs) was successfully achieved by in situ deposition of HKUST-1 via a DMF-free green process. The synthetized HKUST-1/ CF composite exhibited excellent antibacterial activity against Escherichia coli and Staphylococcus aureus. The composite was more effective against Gram-positive S. aureus than Gram-negative E. coli. The optimization of process variables indicated that the novel composite could be prepared at room temperature for a short time.

“…High antimicrobial activity of copper ions, their oxides and metals/alloys has been demonstrated in various studies [123]. Antibacterial activity of copper is due to immobilization of Cu-NPs with the help of in situ formation method thus results in great fouling control [124]. Chen et al [125] fabricated hybrid PES membrane via phase inversion method using copper ions and halloysite nanotubes as nanofillers, resulted in nanohybrid membrane with efficient biofouling control.…”

During last few decades, membrane technology has emerged as an efficient technique over conventional methods due to its high removal capacity, ease in operation and cost effectiveness for wastewater treatment and production of clean water. Membrane based separations are commonly based on polymeric membranes because of their higher flexibility, easily pore forming mechanism, low cost and smaller space for installation as compared to inorganic membranes. Commonly employed membrane fabrication phase inversion method has been shortly reviewed in this article. Major limitation of membrane based separations is fouling and polymeric membranes being hydrophobic in nature are more prone to fouling. Fouling is a deposition of various colloidal particles, macromolecules (polysaccharides, proteins), salts etc. on membrane surface and within pores thus impedes membrane performance, reduces flux and results in high cost. Modification of polymeric membranes due to its tailoring ability with nanomaterials such as metal based and carbon based results in polymeric nano-composite membranes with high antifouling characteristics. Nanomaterials impart high selectivity, permeability, hydrophilicity, thermal stability, mechanical strength, and antibacterial properties to polymeric membranes via blending, coating etc. modification methods. Characterization techniques has also discussed in later section for studying morphological properties and performance of polymer nano-composite membranes. Graphical Abstract

“…Li et al synthesized copper oxide nanoparticles with different shapes and studied the antibacterial activity of these nanoparticles on 4 different strains where it revealed that the inhibition zone was obtained only when the plates were treated with higher volumes of nanoparticles (1 mg ml −1 to 8 mg ml −1 ) [22]. Below 1 mg ml −1 concentration of copper oxide nanoparticle the zone was negligible whereas for Cu 2 O-Ag nanoparticles the presence of both copper oxide and silver inhibits the cell multiplication at lower volumes indicating the synergistic effect of both the elements against the bacteria.…”

Copper and silver are known to have good antibacterial and anti-fungal properties at nanoscale. Cu 2 O-Ag synthesis was attempted using hydrazine hydrate reduction method. The formation of Cu 2 O-Ag nanoparticles was confirmed using powder x-ray diffraction technique. Further the morphology and elemental compositions were analyzed by FESEM, HRTEM and XRF techniques. The antibacterial activity of the formed nanoparticles exhibited an excellent zone of inhibition compared to the existing antibiotics. The microbial broth curve obtained against Pseudomonas aeruginosa further confirmed the remarkable inhibiting property of the nanoparticle in a short span of 6 h post treatment (HPT). The synthesized nanoparticle showed very good activity against HCT-15 colon cancer cells by inhibiting their viability up to 27% when treated at higher concentration. Thus the synthesized nanoparticles seem to be a good candidate for various biological applications.
