元素零价铜纳米粒子的合成与表征。由M.心理耐受者可稳定达3个月。铜纳米粒子的生长抑制特性。在纳米颗粒生产中,必须考虑许多重要因素。生产尺寸和形状均匀的纳米颗粒至关重要,但同样重要的是确保生产过程在时间、成本和能源方面尽可能高效。传统的化学和物理方法生产纳米颗粒通常涉及高温和高压,以及使用有毒基质;相比之下,纳米颗粒的生物生产更环保,需要更少的能源投入。在这里,我们概述了一种在室温下直接生物生产稳定,均匀的元素(零价)铜纳米粒子的方法,并演示了如何通过随后的pH值操作来修改它们的大小和形状。我们还强调了这些生物源铜纳米粒子的潜在应用,通过展示其抑制细菌生长的潜力。
Synthesis and characterization of elemental, zero-valent copper nanoparticles. Copper nanoparticles synthesised by M. psychrotolerans are stable for up to 3 months. Growth inhibiting properties of copper nanoparticles. In nanoparticle production there are a number of important considerations that must be made. Producing nanoparticles of uniform size and shape is vital, but no less important is ensuring the production process is as efficient as possible in time, cost and energy. Traditional chemical and physical methods of nanoparticle production often involve high temperatures and pressures, as well as the use of toxic substrates; in contrast the bioproduction of nanoparticles is greener and requires a smaller input of energy resources. Here we outline a method for the straightforward bioproduction of stable, uniform elemental (zero-valent) copper nanoparticles at room temperature, and demonstrate how their size and shape can be modified by subsequent pH manipulation. We also highlight a potential application for these biogenic copper nanoparticles by demonstrating their potential to inhibit bacterial growth.
