In this study, copper films were deposited by magnetron sputtering on poly(ethylene terephthalate) knitted textile to fabricate multi-functional, antimicrobial composite material. The modified knitted textile composites were subjected to microbial activity tests against colonies of Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacteria and antifungal tests against Chaetomium globosum fungal molds species. The prepared samples were characterized by UV/VIS transmittance, scanning electron microscopy (SEM), tensile and filtration parameters and the ability to block UV radiation. The performed works proved the possibility of manufacturing a new generation of antimicrobial textile composites with barrier properties against UV radiation, produced by a simple, zero-waste method. The specific advantages of using new poly(ethylene terephthalate)-copper composites are in biomedical applications areas.

“…The antibacterial property of PET-based fabrics is considered to be a critical indicator for functional applications in terms of non-antibacterial properties of neat PET-based fabrics. In recent years, several antibacterial agents have been applied for improving their bacterial inhibition growth abilities [41]. Silver nanoparticles (AgNPs) have been regarded as emerging antibacterial agents with unique properties [42].…”

A Novel Coloration of Polyester Fabric through Green Silver Nanoparticles (G-AgNPs@PET)

et al. 2019

This paper reports a novel route for the coloration of polyester fabric with green synthesized silver nanoparticles (G-AgNPs@PET) using chitosan as a natural eco-friendly reductant. The formation of AgNPs was confirmed by UV-visible spectroscopy. The morphologies and average particles size of G-AgNPs was investigated by transmission electron microscope (TEM) analysis. The uniform deposition of G-AgNPs on the PET fabric surface was confirmed with scanning electron microscopy (SEM) and Fourier transform infrared (FT-IR) spectroscopy. The thermal properties were investigated using a thermogravimetric analyzer (TGA). The coloration and fastness properties of fabric were found to be significantly improved, a result related to the surface plasmon resonance of G-AgNPs. The antibacterial properties of fabric were also found to be excellent as more than 80% bacterial reduction was noticed even after 10 washing cycles. Overall, the proposed coating process using green nanoparticles can contribute to low-cost production of sustainable textiles.

Bioinspired Spiky Peroxidase‐Mimics for Localized Bacterial Capture and Synergistic Catalytic Sterilization

et al. 2021

Nature has created an efficient sterilization model, i.e., the in situ bacterial capture and killing process via bacteriophages. The bacteriophage is a virus with a unique spiny tail foot; in general, it can capture bacteria and subsequently release nucleic acid to achieve replication and kill bacteria. We define this two-steps process as the localized "capture and killing" (LCK) action. Therefore, it is believed that this bioinspired LCK action may provide massive possibilities for developing efficient disinfection strategies as alternatives to conventional clinical antibiotic treatments. Two concepts must be carefully designed and integrated to construct the bionic nanosystem with LCK action. i) Developing the spiky nanostructures to enhance the interactions between nanomaterials and pathogenic bacteria; [11,12] meanwhile, the spiky structure must be mesoporous to load and release bactericidal substances. [13] ii) Second, developing an efficient and robust bactericidal system without using any antibiotics. [14-18] Compared to many traditional bactericidal molecules, antibacterial strategies based on reactive oxygen species (ROS) have been intensively studied. [19] Due to its short life cycle, ROS can only cause irreversible damage to substances immediately around it. This spatially confined activity helps to develop targeted applications as well as guarantee excellent biocompatibility during usage. [20,21] Moreover, the molecular weight of ROS is very Besides the pandemic caused by the coronavirus outbreak, many other pathogenic microbes also pose a devastating threat to human health, for instance, pathogenic bacteria. Due to the lack of broad-spectrum antibiotics, it is urgent to develop nonantibiotic strategies to fight bacteria. Herein, inspired by the localized "capture and killing" action of bacteriophages, a virus-like peroxidase-mimic (V-POD-M) is synthesized for efficient bacterial capture (mesoporous spiky structures) and synergistic catalytic sterilization (metalorganic-framework-derived catalytic core). Experimental and theoretical calculations show that the active compound, MoO 3 , can serve as a peroxocomplex-intermediate to reduce the free energy for catalyzing H 2 O 2 , which mainly benefits the generation of •OH radicals. The unique virus-like spikes endow the V-POD-M with fast bacterial capture and killing abilities (nearly 100% at 16 µg mL-1). Furthermore, the in vivo experiments show that V-POD-M possesses similar disinfection treatment and wound skin recovery efficiencies to vancomycin. It is suggested that this inexpensive, durable, and highly reactive oxygen species (ROS) catalytic active V-POD-M provides a promising broad-spectrum therapy for nonantibiotic disinfection. The global pandemic caused by the outbreak of coronavirus has aroused tremendous attention across broad scientific communities. Besides the coronavirus pandemic, many other pathogenic microbes also pose a devastating threat to human health. For instance, pathogenic bacteria have infected millions of people and caused almos...
