“…Furthermore our nano particles (samples a and b) in contrast of paper 25 of reference has less toxicity and has more magnefitication and crystallization. It was shown in TEM that samples c and d in contrast of paper 26 of reference included smaller nano particles and smaller surface in magnetic saturation figure in analyzes. Our samples have less toxicity even in high doze of nano particles (samples d and c) and cells have more mobility for producing and growing cells.…”

Objective: The expansion of wet chemical method for the synthesis of iron oxide nanoparticles with magnetic properties is reported. Methods: Iron oxide nanoparticles were investigated in the procedure using Transmission Electron Microscopy (TEM). It has been seen that the distribution size changed by changing of Molarity precursor and heating the sample. The magnetization evaluations were performed using a Vibrating Sample Magnetometer device (VSM) to specify the magnetic answer. The Thermo Gravimetric Analyses (TGA) displayed the size-dependent weight loss of the magnetic nanoparticles. In this work, the cytotoxic activity of various samples of Maghemite on cancer cell lines HELA was studied. The in vitro cytotoxicity tests were also performed to determine the cell viability as a work of size and heat of the magnetic nanoparticles. Results: The samples c and d at T=300°C had a little magnetic hysteresis that can use in cancer cure with hyperthermia therapy method. Conclusions: These samples became amorphous and they were nontoxicity.

“…Due to its highly effective ability to catalyze redox processes, nano-Fe has been widely applied in the degradation of halogenated organic compounds and other persistent toxic substances (Li et al 2009). Oxidative damage and the low cytotoxicity caused by nano-Fe have been reported (Zhou et al 2003;Li et al 2009;Song et al 2009). Regardless of the synthesis method or particle morphology, Fig.…”

To offer an insight into the toxicity of nanomaterials (NM) on the growth of bacteria, Escherichia coli (E. coli), Bacillus subtilis (B. subtilis) and Agrobacterium tumefaciens (A. tumefaciens) were exposed to nanoAu, nano-Ag, nano-Fe and fullerene (C 60 ) in this study. As an effective bactericide, nano-Ag induced high toxicity on these three bacteria; C 60 could inhibit their growth; however, B. subtilis and E. coli could recover as exposure time extended. Nano-Au and nano-Fe had hardly any effect on three bacteria. A. tumefaciens showed the lowest resistance and slowest growth rate during exposure. Images obtained by scanning electron microscope (SEM) revealed that nano-Ag could cause damage to the cell structure of three bacteria at 1 lg/mL. Slight damage on E. coli was found when exposed to C 60 , whereas no obvious physical damage was found after exposure to nano-Au or nano-Fe. It is assumed that surface activities of NM might be responsible for the different toxic effects on these bacteria.

We briefly reviewed the existing research on the ecotoxicity of nanowires and suggested directions for further study. Nanowires are technological innovations that can benefit humans. However, it is important to consider the effects of nanowires on the environment. Only a few studies have reported acute and chronic ecological toxicity of nanowires on aquatic and terrestrial organisms, and limited research papers have reported antibacterial effects of nanowires. It is assumed that nanowires have a toxic mechanism similar to that of nanoparticles or ions, but the mechanism remains unknown because so little research has been conducted on the ecological toxicity of nanowires. More in-depth assessments of the chronic toxicity, bioavailability, cytotoxicity, and genotoxicity of nanowires on various species are needed.
