“…The zone of inhibitions for S. aureus increased from 9.5 to 15.5 mm, while for E. coli it increased from 7.5 to 12 mm with increasing number of dips (Figure 12). The antibacterial property of coated fabrics can be attributed to the combination of chemical and physical interactions of bacteria with copper particles [24, 25]. The mechanisms associated with the antibacterial behavior of copper nanoparticles can be summarized as shown in Figure 13.…”

The present work deals with the development of electrically conductive cotton fabrics by in-situ deposition of copper particles. The dynamic light scattering, scanning electron microscope, and X-ray diffraction techniques were employed to study the morphology of deposited copper particles. The utility of conductive fabrics was analyzed for electromagnetic shielding ability over frequency range of 30 MHz to 1.5 GHz. The electromagnetic interference shielding was found to increase with increase in number of dips, which was attributed to increased reflection of EM waves due to dense, uniform, and percolated network of conductive copper particles on the surface. The sample produced from 100 and 150 dips exhibited the maximum shielding ability of 10 dB and 13 dB, respectively. Furthermore, the role of deposited copper particles on antibacterial properties was examined against pathogenic bacteria such as Staphylococcus aureus and Escherichia coli. The S. aureus showed more sensitivity towards copper particles as zone of inhibitions increased from 9.5 to 15.5 mm. At the end, the durability of fabrics was examined against washing after application of binder. The fabrics showed good retention of the copper particles, proved by scanning electron microscopic microstructures and small loss in the conductivity of the material after washing.

“…The cell density was expressed as Log 10 of the colony-forming units per mL (Log 10 CFU/mL) and the average values and standard deviations were then calculated and plotted using Prim 7 (GraphPad, San Diego, CA, USA). A bacteriostatic effect was considered to have occurred when the decrease in the inoculum was >2 Log 10 and <3 Log 10 and a bactericidal effect was considered to have occurred when the cell density decrease was ≥3 log 10 [ 13 , 14 , 15 ].…”

Copper-Polyurethane Composite Materials: Particle Size Effect on the Physical-Chemical and Antibacterial Properties

et al. 2020

In this work, thermoplastic polyurethane (TPU) composites incorporated with 1.0 wt% Cu particles were synthesized by the melt blending method. The effect of the incorporated copper particle size on the antibacterial, thermal, rheological, and mechanical properties of TPU was investigated. The obtained results showed that (i) the addition of copper particles increased the thermal and mechanical properties because they acted as co-stabilizers of polyurethane (PU) (ii) copper nanoparticles decreased the viscosity of composite melts, and (iii) microparticles > 0.5 µm had a tendency to easily increase the maximum torque and formation of agglomerates. SEM micrographics showed that a good mixture between TPU and copper particles was obtained by the extrusion process. Additionally, copper-TPU composite materials effectively inhibited the growth of the Gram-negative Escherichia coli and the Gram-positive Staphylococcus aureus. Considering that the natural concentration of copper in the blood is in the range of 0.7–0.12 mg/L and that the total migration value of copper particles from TPU was 1000 times lower, the results suggested that TPU nanocomposites could be adequately employed for biomedical applications without a risk of contamination.

“…The antimicrobial properties of copper have been appreciated for centuries, and today, copper is used in medical devices to prevent fouling from microbial growth (58,59). Appropriately, the mammalian immune system also uses copper's toxicity to prevent microbial growth.…”

Transition metals have been recognized and studied primarily in the context of their essential roles as structural and metabolic cofactors for biomolecules that compose living systems. More recently, an emerging paradigm of transition metal signaling, where dynamic changes in transition metal pools can modulate protein function, cell fate, and organism health and disease, has broadened our view of the potential contributions of these essential nutrients in biology. Using copper as a canonical example of transition metal signaling, we highlight key experiments where direct measurement and/or visualization of dynamic copper pools, in combination with biochemical, physiological, and behavioral studies, have deciphered sources, targets, and physiological effects of copper signals.
