摘要

本文采用简便可行的绿色合成方法,以Styrax officinalis果皮为原料合成氧化锌纳米颗粒(ZnO-NPs)。尺寸约为17.53 nm的球形ZnONPs的间接带隙为3.25 eV。在476±4.0 cm−1处,NPs的Zn-O拉伸带出现了轻微的团聚。采用XRD分析确定了Styrax-ZnO-NPs的物相组成。通过抑制内源性分子信号的QS调控,检测了NPs对两种参比菌的抗毒活性。ZnO-NPs表现出剂量依赖性的效果,最大可使C. violaceum 12472和P. aeruginosa PA01的色素产量分别减少99.82%和82.36%。ZnO-NPs的抗氧化活性为14.94±0.00 μg TE /mg磷钼酸盐。此外,ZnO-NPs在最低抑菌浓度(0.25 mg/mL)较低时,对大肠杆菌25922有较强的抑菌能力。因此,我们的研究结果为开发Styrax-ZnO-NPs作为治疗致病性感染的替代治疗剂提供了见解。

Styrax officinalis-mediated synthesis of ZnO-NPs potentially quorum sensing nano inhibitor
We synthesized zinc oxide nanoparticles (ZnO-NPs) using an easy and applicable green approach using Styrax officinalis pericarp. The indirect band gap of sphere-shaped ZnONPs with about 17.53 nm size was 3.25 eV. The Zn-O stretching band of NPs showing slight agglomeration was observed at 476 ± 4.0 cm−1. The XRD analysis was carried out to determine the phase composition of Styrax-ZnO-NPs. The anti-virulence activity of NPs via inhibiting endogenous molecular signals-based QS regulation was tested for the two reference bacteria. ZnO-NPs displayed a dose-dependent efficacy, reducing a maximum of 99.82 and 82.36 % pigment production in C. violaceum 12472 and P. aeruginosa PA01, respectively. ZnO-NPs exhibited considerable antioxidant potential with a 14.94 ± 0.00 μg TE /mg phosphomolybdate activity. Moreover, ZnO-NPs showed bactericidal potency at the low minimum inhibitory concentration (0.25 mg/mL) against E. coli 25922 strain. Thus, our outcomes present an insight into the exploitation of Styrax-ZnO-NPs as an alternative therapeutic agent for the therapy of pathogenic infections.

期刊介绍: The journal offers a common reference and publication source for workers engaged in research on the experimental and theoretical aspects of crystal growth and its applications, e.g. in devices. Experimental and theoretical contributions are published in the following fields: theory of nucleation and growth, molecular kinetics and transport phenomena, crystallization in viscous media such as polymers and glasses; crystal growth of metals, minerals, semiconductors, superconductors, magnetics, inorganic, organic and biological substances in bulk or as thin films; molecular beam epitaxy, chemical vapor deposition, growth of III-V and II-VI and other semiconductors; characterization of single crystals by physical and chemical methods; apparatus, instrumentation and techniques for crystal growth, and purification methods; multilayer heterostructures and their characterisation with an emphasis on crystal growth and epitaxial aspects of electronic materials. A special feature of the journal is the periodic inclusion of proceedings of symposia and conferences on relevant aspects of crystal growth.
