Abstract ZnSe nanocrystals (NCs) were synthesized by aqueous method and were grown by microwave irradiation times (MWIRT) of 0-6 min at fixed solution pH of 11.2. Disk diffusion antibacterial property of these nanocrystals owing the mean size of ∼2 nm, was carried out against the gram negative bacteria of Escherichia coli and Pseudomonas aeruginosa, by considering nanoparticle loading volumes of 140 and 70 microliter, showing good control over the mentioned bacteria; the maximum inhibition level at different MWIRT is devoted to Pseudomonas aeruginosa with average inhibition zone diameter of 10.10 – 11.58 mm for volume of 140 microliter and 7.42-10.67 mm in volume of 70 microliter, implying an increasing trend with increase of loading volume/ decrease of NCs size. So, these nanomaterials, which can be prepared in a simple and cost-effective manner, may be suitable as new types of bactericidal materials.

不同微波辐射时间下纯ZnSe纳米晶体的水热制备及其对革兰氏阴性菌的圆盘扩散抗菌潜力:生物光学优势

摘要 ZnSe 纳米晶体 (NCs) 通过水法合成,并在固定溶液 pH 值为 11.2 的条件下通过 0-6 分钟的微波辐射时间 (MWIRT) 生长。这些纳米晶体的圆盘扩散抗菌性能由于平均尺寸约为 2 nm,通过考虑 140 和 70 微升的纳米颗粒加载体积,对革兰氏阴性菌大肠杆菌和铜绿假单胞菌进行了研究,显示出对上述细菌的良好控制;不同MWIRT的最大抑制水平专用于铜绿假单胞菌,平均抑菌圈直径为140微升的10.10-11.58毫米和70微升的7.42-10.67毫米,表明随着装载量的增加/减少NC 大小。因此,这些可以以简单且具有成本效益的方式制备的纳米材料,
