Cerium oxide nanoparticles (CeO 2 NPs) were synthesized using Aspergillus niger culture filtrate. The mycosynthesized CeO 2 NPs were characterized by UVVisible (UV-Vis), Fourier Transform Infrared (FT-IR), X-ray diffraction (XRD), Micro Raman, Thermogravimetric/Differential Thermal Analysis (TG/DTA), Photoluminescence, and Transmission Electron Microscopy (TEM) analyses. UV-Vis spectrum exhibited a corresponding absorption peak for CeO 2 NPs at 296 nm, and the functional groups present in the fungal filtrate responsible for the synthesis of NPs were analyzed by FT-IR. The further characterization of the mycosynthesized CeO 2 NPs revealed particles of the cubic structure and spherical shape, with the particle sizes ranging from 5 to 20 nm. The antibacterial activity of CeO 2 NPs was examined in respect of two Gram-positive (G?) bacteria (Streptococcus pneumoniae, Bacillus subtilis) and two Gram-negative (G-) bacteria (Proteus vulgaris, Escherichia coli) by disk diffusion method. The test results for CeO 2 NPs at a concentration of 10 mg/mL showed higher activities on the zone of inhibition of up to 10.67 ± 0.33 and 10.33 ± 0.33 mm against Streptococcus pneumonia and Bacillus subtilis, respectively, The CeO 2 NPs caused 100 % mortality on first instar of Aedes aegypti at 0.250 mg/L concentration after 24-h exposure. The mycosynthesis of CeO 2 NPs is a simple, cost-effective and eco-friendly approach and it will also potentially helpful to control pathogenic bacteria and dengue vector.

“…Seed or seedling treatment with Au NPs (62 µg mL −1 ) improved seed germination in Lactuca sativa and Cucumis sativus , Brassica juncea (10 ppm), and Gloriosa superba (1000 µ m ) . Au NP treatments also enhanced plant growth and yield, including the number, area, and chlorophyll and sugar content of leaves, and 10 and 80 µg mL −1 Au NPs promoted antioxidant production and seed germination in Arabidopsis thaliana . These positive effects, however, may be connected with stimulation of biochemical pathways as the response on the low doses of xenobiotics.…”

In this Review, an effort is made to discuss the most recent progress and future trend in the two‐way traffic of the interactions between plants and nanoparticles (NPs). One way is the use of plants to synthesize NPs in an environmentally benign manner with a focus on the mechanism and optimization of the synthesis. Another way is the effects of synthetic NPs on plant fate with a focus on the transport mechanisms of NPs within plants as well as NP‐mediated seed germination and plant development. When NPs are in soil, they can be adsorbed at the root surface, followed by their uptake and inter/intracellular movement in the plant tissues. NPs may also be taken up by foliage under aerial deposition, largely through stomata, trichomes, and cuticles, but the exact mode of NP entry into plants is not well documented. The NP–plant interactions may lead to inhibitory or stimulatory effects on seed germination and plant development, depending on NP compositions, concentrations, and plant species. In numerous cases, radiation‐absorbing efficiency, CO2 assimilation capacity, and delay of chloroplast aging have been reported in the plant response to NP treatments, although the mechanisms involved in these processes remain to be studied.

“…The use of NPs is considered as a substitute for antibiotics with better efficacy with negligible side effects and for combating bacterial multidrug resistance. The green synthesized metal or metal oxide NPs have potent antibacterial, antifungal as well as antiparasitic activities [72][73][74][75][76] . The toxicity of metal NPs can be analyzed by various in vitro and in vivo studies.…”

Qidwai, et al.: Biogenic Advances in NanoparticlesInnovations in the nanotechnological arena have paved a path leading to nano-revolution, which has most recently unfurled the role of plants in the biogenic synthesis of nanoparticles. Though synthesis of nanoparticles can be accomplished through physical and chemical techniques, biological course of synthesis has proficiently proved competent over other techniques. The problem of evolving multidrug resistant bacteria, due to irrational use of antibiotics, makes the biogenically synthesized nanoparticles attractive, due to their promising efficacy with negligible side effects. Consequently, the nanoparticles becoming better substitutes for conventional treatment besides overcoming all the limitations. Nanoparticles have great stability and potent antibacterial activity. The uniqueness lies in their size (10 and 500 nm) and dimension offers these particles to dynamically communicate with biomolecules on the cell surfaces and within the cells, so proficiently to decode and designate various biochemical and physiochemical properties of the cells. The present review aims to recapitulate various emerging efforts in the biogenic synthesis of nanoparticles, most significantly their unique mechanisms of action with different approaches as well as the factors that may add up to their antimicrobial activity.
