“…The CuONPs obtained in this study have a small size range and quasi-spherical and/or irregular shape, similar to other biologically synthesized copper nanoparticles [ 23 , 24 , 25 ], and those using fungal extracts as reducing agents [ 26 , 27 ]. The CuONPs were analyzed by DLS to measure the hydrodynamic diameter (HD) and determine their zeta potential.…”

Candida albicans (ATCC SC5314) was exposed to biosynthesized copper oxide nanoparticles (CuONPs) to determine their inhibitory capacity. Nanoparticles were polydisperse of small size (5.8 ± 3.5 nm) with irregular shape. The minimum inhibitory concentration (MIC) against C. albicans was 35.5 µg/mL. The production of reactive oxygen species (ROS) of C. albicans was verified when exposed to different concentrations of CuONPs. Ultrastructural analysis of C. albicans revealed a high concentration of CuONPs in the cytoplasm and outside the cell; also, nanoparticles were detected within the cell wall. Cytotoxic analyses using fibroblasts (L929), macrophages (RAW 264.7), and breast (MCF-12) cell lines show good results of cell viability when exposed at the MIC. Additionally, a hemocompatibility analysis was carried out and was found to be below 5%, considered the threshold for biocompatibility. Therefore, it is concluded that the biosynthesized CuONPs have a high potential for developing a topical antifungal treatment.

“…Other than chemical and physical processes, the green method of obtaining metallic copper has also been successfully explored owing to their low cost and eco-friendly nature bearing no adverse impacts on the environment ( Suresh et al., 2013 ) ( Figure 2 ). The green method involves the use of plant extracts or metabolic activities of microorganisms like bacteria and fungi for the reduction of Cu II to Cu 0 ( Thiruvengadam et al., 2019 ).…”

“…At high concentrations of nanoparticles, the negative effect on dehydrogenase enzymes activity was observed [42]. Another negative effect caused by nanoparticles is the influence on the rate of soil self-cleaning as well as on the balance of nutrients, which is the basis for the regulation of the processes of plant nutrition and soil fertility improvement [43,44]. It is significant to study presence of nanoparticle in soil and their influence on soil biodiversity [45].…”

Nanotechnology proved as a boon to this era and is widely applied in many areas of science and technology. Agriculture is the backbone of industrial raw material and it is very important to have technologies supporting high yield, better crop production and protection in a cost effective, ecofriendly and sustainable way. Globally, there is a lot of research being conducted in the field of application of nanoparticles in agriculture. In recent time nano-based materials like nanoparticles and nanoformulations, nano-based fertilizers, nano-pesticides and insecticides, nano fungicides and other plant disease control formulations are available in the market. Though this technology offers many advantages, yet there are some vices which is causing the concern among the researchers and practitioners. The unregulated exposure of the nanoparticles to the soil is expected to cause adverse effects on the soil microbiota and in some cases negatively impact the important adaphic factors like soil infertility and toxicity. The studies conducted so far have shown diverse responses of nanoparticles by soil fungi and soil bacteria. The enzymatic activities of the microbes have been reported to be affected when the stress is induced from different sources. In some studies, silver nanoparticles have been found to decrease FDA-hydrolysis in soil. More research still needs to be done on addressing the nanoparticle induced metal-stress by different microbes. This review provides the comprehensive account of side effects of the nanoparticles on soil fertility and their effect on the different properties of soil and plant growth along with the research gaps in the field of soil application of nanoparticles and way forward to introduce an ecofriendly application of nanoparticles.
