“…Biological or biosynthesis [14] techniques are also considered as chemical methods. Cu NP has high thermal conductivity [15] and also the production cost is very low as compare to noble metals. Cu NP production using chemical reduction method gives good results but use of hazardous reducing and costly and protecting agent [16][17][18][19][20][21][22] makes the process toxic in some cases.…”

“…To avoid the toxicity and to prepare Cu NP in green environment, we have used ascorbic acid in our chemical reduction process. Ascorbic acid works both as reducing and protecting agent, which makes the process economical, nontoxic and environment friendly [15]. The raw materials are the same as Jing Xiong [23]; however, the synthesis route and the equipments have been changed, which resulted in the size variation of NP in this work.…”

Chemical Reduction technique was employed to prepared highly stable and dispersed Copper nanoparticles using L-Ascorbic Acid (Vitamin C) as reducing as well as capping agent. In this technique, cupric chloride was used as precursor. The effects of different molar ratios of L-Ascorbic Acid on the concentration and size of copper nanoparticles were studied. The Copper nanoparticles were characterized by X-Ray Diffraction, Atomic Absorption Spectrometry, and Fourier Transform Infrared Spectrometry. The results show that with the increase in the molar ratio of L-ascorbic acid the concentration of Copper nanoparticles were also increased. The average particles size of copper nanoparticle was found in the range of 50-60 nm. The product was kept in ambient conditions for three month but no sedimentation or separation was observed. The use of ascorbic acid makes the process a non-toxic, cost effective and environmental friendly green method.

“…Different studies have shown that the limited bioavailability of many nanoparticles in aqueous environments occur due to their low solubility and tendency to accumulate leading to toxicity, and these substances can be toxic to many aquatic organisms (Piotrovskii and Kiselev 2006;Zuykov et al 2013). Among various nanoparticles, zinc nanoparticles are widely used in various fields due to their simple access, low cost and specific physical and chemical properties (Umer et al 2012;Fan et al 2017). Despite the large production and application of zinc nanoparticles, which its effluent consequently is being released into the environment, the information about the possible effects of these substances on living organisms is limited.…”

Abstract. Qadermarzi A, Pouladi M, Rezamand A, Hoseinifar SH, Hedayati AA. 2018. Investigation of sub-acute levels of zinc oxide nanoparticles on the filtration rate of Mytilaster lineatus and Dressina polymorpha in the short term. Nusantara Bioscience 10: 53-57. The filtration rate is one of the physiological indices in the bivalves which indicate the degree of efficacy of the filtration function in the exposure to contaminants. In this study, changes in the filtration rate of freshwater bivalves (D. polymorpha and M. lineatus) were investigated after exposure periods of 5 and 10 days with nanoparticles. Bivalves were transferred from the natural environment to the laboratory. The distribution of nanoparticles was measured by differential light scattering (DLS). Bivalves were exposed to 2.5, 25 and 50 ppm nanoparticles for ten days in water reservoirs. The filtration rates were significantly different in the treatments compared to the control samples, with the highest filtration rate was observed in the control group. On the fifth day, the highest filtration rate was obtained in the first treatment of M. lineatus and the lowest filtration rate was obtained in the third treatment of D. polymorphia. The highest filtration rates were observed in the first and second treatments and the lowest filtration rate was observed in the third treatment. Also, there was no significant difference in the filtration rate of M. lineatus in the 1 st treatment with control (P> 0.05) on the 5 th day, but filtration rate was significantly (P <0.05) less than other concentrations and control group in the third treatment. On the other hand, the filtration rates on the 10 th day showed similar differences compared to the 5 th day. It could be concluded that the changes infiltration rate are an appropriate indicator for the measurement of contamination in nanoparticles.

In this study, synthesis of copper nanoparticles was performed using organoclay as a support to stabilize the nanoparticles. Organoclay amount was gradually increased, which had an effect on the morphology of the resultant nanoparticles. Low amount of organoclay added resulted in larger and agglomerated copper nanoparticles whereas increased amount of organoclay gave smaller sized nanoparticles. The hybrid materials were characterized using the SEM and TEM for morphology, XRD and FT-IR spectroscopy for structural elucidation, thermal analysis using TGA and also studying their antibacterial effect on the two well-known gram negative bacteria of E. coli and P. Aeruginosa. The synthesized nanoparticles were found to be crystalline Cu nanoparticles with a mix of CuO. Larger sized copper nanoparticles and agglomerates showed the higher thermal behaviour as compared with smaller nanoparticles with higher organoclay loading. The hybrid showed an improved antibacterial activity as compared with organoclay alone. The hybrid showed the higher antibacterial effect against the P. aeruginosa microorganism as compared with the E. coli microorganism.
