“…In the UV‒Vis spectrum the maximum peak intensity observed at 466 nm confirms the green synthesis of silver nanoparticles. These finding was is in agreement with data in the UV–Visible spectrum of [ 24 , 25 ]. The broadness of the peak indicates the presence of polydispersed nanoparticles particles as discussed by Ibrahim et al in (2021) [ 26 ] who attributed the broadness of absorption band due to an increasing of a particle size distribution.…”

“…The appearance of all functional groups in FTIR analyses in our manuscript as reported by [ 7 , 20 , 25 , 34 ] confirming the structure of bacterial cellulose. The presence of the same functional groups in bacterial cellulose, green synthesized AgNPs and BC incorporated with AgNPs, with some difference in transmittance intensities due to functional groups of AgNPs, indicating the absence of any chemical interaction and the nanocomposite may be formed due to the entrance of silver nanoparticles within the microporous network structure of BC.…”

“…The average size of green synthesized nanoparticles calculated using Deby‐Seherrer equation was 28.5 nm which was nearly in accordance with the results of transmission electron microscopy investigation which indicated that the size of green synthesized silver nanoparticles using moringa oleifera leaf extract ranged between 24 and 40 nm with semispherical shaped nanoparticles [ 25 ].…”

In this study, bacterial cellulose (BC) impregnated with green synthesized silver nanoparticles (AgNPs) is evaluated as an antimicrobial membrane for wound-healing treatment. Green synthesized silver nanoparticles using Moringa oleifera leaf extract were characterized using UV‒visible spectroscopy, FTIR, X-ray diffraction, and transmission electron microscopy. The results confirmed that the resulted particles were Ag2O and metallic Ag in nanoscale with an average size ranged from 24 to 40 nm. The green synthesized nanoparticles incorporated within both bacterial cellulose and filter paper discs showed excellent antibacterial activities against Staphylococcus aureus ATCC 6538 and Pseudomonas aeruginosa ATCC 9027. There was no significant difference noticed between bacterial cellulose and filter paper holding capacity to nanoparticles and there was lack of interaction between bacterial cellulose and impregnated nanoparticles as elaborated by Fourier transform infrared spectral analyses. Scanning electron microscopy investigation showed major distortions effects of green synthesized silver nanoparticles on bacterial cell morphology.

“…Therefore, one strategy is to functionalize BC with antimicrobial agents. Among them, silver nanoparticles (AgNPs) incorporated into BC can impart antimicrobial activity [17][18][19]. Their unique optical properties are due to the localized surface plasmon resonance (LSPR) of AgNPs, which can be easily observed after synthesis.…”

Composite nanomaterials based on silver nanoparticles (AgNPs) are considered promising antimicrobial agents due to their excellent antimicrobial activity. The aim of this work is to develop bacterial cellulose (BC) composites that act synergistically with AgNPs. BC@AgNPs composites were developed using an ex-situ composite development strategy and evaluated for their structural characteristics and antimicrobial activities. Field emission scanning electron microscopy (FESEM) showed impregnation of AgNPs into the porous BC network. The composite formulation was also confirmed by X-ray diffraction (XRD) analysis, which showed the presence of additional crystalline peaks along with those of the pure BC. Bactericidal tests of BC@AgNPs nanocomposites against common pathogens, including Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli, showed a significant reduction in their growth compared to pure BC. These results suggest that the synthesized BC@AgNPs composites could be promising antibacterial materials for potential applications in a wide range of medical and environmental applications.

“…AgNPs and AgNP based composite materials have been shown effective agents for inhibition of a wide range of antibiotic resistant strains, including Gram-negative and Gram-positive bacteria [40][41][42][43][44]. They act in a manner similar to the antimicrobial agents utilized for the treatment of bacterial infections.…”

Nanometer sized particulates demonstrate significant potential in various biomedical applications due to their large surface-to-volume ratio and exceptional physicochemical, electronic and mechanical properties. Additionally, the number of microbial infectious disease outbreaks has increased tremendously over the past decade, greatly impacting public health worldwide. In this article, we evaluate the antimicrobial activity of a cotton fabric (CF) impregnated with silver nanoparticles (AgNPs) and hemp hurd activated carbon (HHAC) (HHAC@AgNPs) composite (CF-HHAC@AgNPs). Field emission scanning electron microscopy and X-ray diffraction spectra of the CF-HHAC@AgNPs material revealed the presence of AgNPs and HHAC on the cotton fabric. Moreover, CF-HHAC@AgNPs shows excellent antimicrobial efficacy against Gram-positive and Gram-negative pathogens. The obtained results show that an HHAC@AgNPs-CF material can be prepared. It has an antimicrobial activity that suggests its potential as an inhibitory agent in various biomedical applications.
