Because of their immense economic, wellness, and remedial value, the seeds of palm (Phoenix dactylifera) were selected with synthesized silver nanoparticles (AgNPs) based on their properties for increasing the antibacterial efficacy of medical cotton. This study aimed to be contingent upon the characterisation of raw cotton fabrics treated by AgNPs with date seed extract (DSE) of P. dactylifera both individually and in combination and to investigate their antibacterial activity against various human pathogens. The prepared cotton materials with the synthesized AgNPs and/or DSE were described by both X-ray diffraction (XRD) and scanning electron microscope (SEM). At the same time, gas chromatography-mass spectrometry (GC-MS) and High-performance liquid chromatography (HPLC) were employed to determine the bioactive components in the aqueous date seed extract. The greater antibacterial activity was recorded by cotton treated with DSE and AgNPs mix, in which inhibition zones of all treatments were against Escherichia coli (8 cm), followed by Staphylococcus aureus (2.33-5.87cm) and Bacillus subtilis (2.17-4.63 cm), respectively. Overall, these findings indicate that treated cotton fabrics with synthesised AgNPs and DSE may be widely applied in various potential biological and medical applications, which could enhance environmental sustainability in closed production and consumption.
由于其巨大的经济、健康和治疗价值,基于其特性,选用了枣椰树(Phoenix dactylifera)种子与合成银纳米颗粒(AgNPs)来提高医用棉的抗菌效果。本研究旨在取决于用AgNPs与枣椰树种子提取物(DSE)单独或联合处理的原棉织物的表征,并研究它们对各种人类病原体的抗菌活性。用X射线衍射(XRD)和扫描电子显微镜(SEM)对制备的含有合成AgNPs和/或DSE的棉材料进行了描述。同时,采用气相色谱-质谱联用(GC-MS)和高效液相色谱(HPLC)来测定枣椰树种子水提取物中的生物活性成分。用DSE和AgNPs混合物处理的棉花表现出更强的抗菌活性,其中所有处理的抑菌圈分别针对大肠杆菌(8厘米),其次是金黄色葡萄球菌(2.33 - 5.87厘米)和枯草芽孢杆菌(2.17 - 4.63厘米)。总体而言,这些发现表明,用合成AgNPs和DSE处理的棉织物可能广泛应用于各种潜在的生物和医学应用中,这可以在封闭的生产和消费中提高环境可持续性。
