“…A combination of three functions in one biological nanostructure (antiadhesive properties of insect ommatidia grating in addition to their widely accepted antireflective properties and ability to reduce glare to predators) can be exploited for the development of industrial multifunctional surfaces capable of enhancing light harvesting while reducing light reflection and adhesion 24. Butterfly wings contain nanostructures that give rise to optical effects such as iridescence, the effect of changing color when viewed from different angles 25. The tokay gecko uses nanotechnology to stick itself to trees, walls, windows, and even ceilings.…”

Mimicking the agile gecko, researchers have created synthetic “gecko tape” with four times the sticking power of the real thing.…”

Nanotechnology is one of the most important tools in modern agriculture, and agri-food nanotechnology is anticipated to become a driving economic force in the near future. Agri-food themes focus on sustainability and protection of agriculturally produced foods, including crops for human consumption and animal feeding. Nanotechnology provides new agrochemical agents and new delivery mechanisms to improve crop productivity, and it promises to reduce pesticide use. Nanotechnology can boost agricultural production, and its applications include: 1) nanoformulations of agrochemicals for applying pesticides and fertilizers for crop improvement; 2) the application of nanosensors/nanobiosensors in crop protection for the identification of diseases and residues of agrochemicals; 3) nanodevices for the genetic manipulation of plants; 4) plant disease diagnostics; 5) animal health, animal breeding, poultry production; and 6) postharvest management. Precision farming techniques could be used to further improve crop yields but not damage soil and water, reduce nitrogen loss due to leaching and emissions, as well as enhance nutrients long-term incorporation by soil microorganisms. Nanotechnology uses include nanoparticle-mediated gene or DNA transfer in plants for the development of insect-resistant varieties, food processing and storage, nanofeed additives, and increased product shelf life. Nanotechnology promises to accelerate the development of biomass-to-fuels production technologies. Experts feel that the potential benefits of nanotechnology for agriculture, food, fisheries, and aquaculture need to be balanced against concerns for the soil, water, and environment and the occupational health of workers. Raising awareness of nanotechnology in the agri-food sector, including feed and food ingredients, intelligent packaging and quick-detection systems, is one of the keys to influencing consumer acceptance. On the basis of only a handful of toxicological studies, concerns have arisen regarding the safety of nanomaterials, and researchers and companies will need to prove that these nanotechnologies do not have more of a negative impact on the environment.

“…The observed microstructures on the outer layer of the T. maxima outer mantle tissues could be potentially part of a light-harvesting system, just as some comparable photonic nanostructures on butterfly wings (Vértesy et al, 2006;Tam et al, 2013) and bird feathers (Eliason et al, 2015) have been previously reported being responsible for controlling how incident light is reflected and scattered. For the butterflies, differences in iridescence were also reported to be due to a difference in those nanostructures, including their optical thickness and the periodicities of air/cuticle bilayer stacks (Tam et al, 2013).…”

“…Substances having size in this range in all three dimensions are called NPs [5, 6]. Although the term is comparatively new to human knowledge, its existence in nature is as old as nature itself, be it in the volcanic dusts, lunar dusts, forest fires, mineral composites, or even changing colours of butterfly wings [7, 8], they had always been present in nature (Fig. 1)!…”

Nanomaterials, recently have found burgeoning attention in the field of agriculture, owing to the positive correlation between nanoparticle (NP) application and the enhanced nutritional status of the applied plants. A wide range of NPs, namely carbon-based NPs, titanium dioxide NPs, silica NPs etc. has been found to influence plants in a positive way by increasing their nutrient uptake ratio, nutrient usage efficiency, among others. All these attributes have paved the way for possible improvement in plant growth, development, vigour etc. through the use of these NPs, mainly as nanofertiliser. In view of all these, it can also be concluded that in the global scenario of increased demand of food production and supply in the coming years, nanotechnology promises to play a critical role. In this review, an attempt has been made to consolidate all the positive trends with respect to application of NPs on plants, along with their probable mechanism of action, which may provide a comprehensive insight for researchers working in this field.
