Abstract

We communicate the results of experimental studies of the effects that different concentrations of maghemite (iron oxide γ-Fe₂O₃) superparamagnetic nanoparticles (SPNPs) have on the growth patterns of algal and yeast cultures. The SPNPs are prepared by laser ablation, an electrophysical technique. In a series of experiments, we establish that different SPNP concentrations (defined relative to the maximum allowable concentration for the total free iron) can have both stimulating and toxic effects on chlorella and yeast cultures.

磁性三氧化二铁（γ-Fe2 O 3）对藻类和酵母培养物生长的影响

摘要

我们进行通信的效果的实验研究的结果，不同浓度的磁赤铁矿（氧化铁了γ-Fe ₂ ö ₃）的超顺磁性纳米粒子（SPNPs）具有对藻类和酵母培养物的生长模式。SPNP是通过激光烧蚀（一种电物理技术）制备的。在一系列实验中，我们确定不同的SPNP浓度（相对于总游离铁的最大允许浓度定义）可以对小球藻和酵母培养物产生刺激和毒性作用。
