The comparative study of in-vitro seed germination was conducted to determine the influence of different concentrations of chemically synthesized copper nanoparticles (CuNPs) on the in-vitro seed germination and growth of two different varieties of wheat-PBW677 and PBW725 on MS medium. For all growth parameters taken under the present study, PBW 725 variety of wheat performed better in the basal MS media having different concentration of CuNPs than PBW 677. 100% germination percentage of PBW 725 variety of wheat is achieved on Basal MS medium supplemented with 5 ppm CuNPs. This variety has better seed vigour and tolerance index. It indicates that a lower concentration of CuNPs is potential enhancer of seed germination of this particular variety. But the higher concentration of the nanoparticles proved to be detrimental and resulted into poor seed germination and decreased morphological development of the plants of both varieties. INTRODUCTION:Wheat is a globally consumed cereal crop, which is a staple food in most part of Asia, Africa, and other parts of the world. Approximately 215 million hectares of land is utilized for wheat cultivation all over the world out of which around 30 million hectares of land is used in India. Wheat is commonly used as a ground, powdery form called wheat flour. It is also used in the preparation of a large variety of food products, including bread, biscuits, cakes, pies, fermented beverages like beer, breakfast cereal, etc. The crop belongs to the family of Poaceae and contains great benefits -carbohydrate 70% and protein 3% and inorganic ions 1.5-2.0%, fat 1.5-2.0%, and vitamins such as B complex and E 1 .

We demonstrate a proof of concept for magnetically-driven 2D cells organization on superparamagnetic micromagnets fabricated by laser direct writing via two photon polymerization (LDW via TPP) of a photopolymerizable superparamagnetic composite. The composite consisted of a commercially available, biocompatible photopolymer (Ormocore) mixed with 4 mg/mL superparamagnetic nanoparticles (MNPs). The micromagnets were designed in the shape of squares with 70 µm lateral dimension. To minimize the role of topographical cues on the cellular attachment, we fabricated 2D microarrays similar with a chessboard: the superparamagnetic micromagnets alternated with non-magnetic areas of identical shape and lateral size as the micromagnets, made from Ormocore by LDW via TPP. The height difference between the superparamagnetic and non-magnetic areas was of ~ 6 µm. In the absence of a static magnetic field, MNPs-free fibroblasts attached uniformly on the entire 2D microarray, with no preference for the superparamagnetic or non-magnetic areas. Under a static magnetic field of 1.3 T, the fibroblasts attached exclusively on the superparamagnetic micromagnets, resulting a precise 2D cell organization on the chessboard-like microarray. The described method has significant potential for fabricating biocompatible micromagnets with well-defined geometries for building skin grafts adapted for optimum tissue integration, starting from single cell manipulation up to the engineering of whole tissues.

“…The final outcome is influenced by a number of factors, including the physical and chemical characteristics of nanoparticles, the kind of plants utilized, and the concentration used. [42,99] While applying NPs to the foliage of certain agricultural crops might boost growth, biomass output, and yield [83,100], it can also lead to nutrient deficiency, root elongation inhibition, and bloom delay in others [38,101]. By releasing toxic ions, interfering with metabolic processes, and generating an imbalance in reactive oxygen species (ROS), NPs have the potential to affect plant growth [102].…”

“…The drought may jeopardize carbon fixation, water absorption, and water transport. According to particular research [40,42], foliar spraying of TiO2 NPs may boost photosynthetic rate by improving enzyme activity and speeding up water photolysis. Glycine and serine are two of the most important amino acids produced during photorespiration, according to a recent research, and their ratio is often utilized as a proxy for photorespiration activity and leaf senescence.…”

The major issues influencing human health in developing countries is the nutrient deficiency in different field crops. Several problems with the low efficiency of using the traditional chemical fertilizers by plants, despite there are more development in agricultural cultivation. Therefore, biofortification with nano-fertilizers and nano-biostimulants have been proposed as potential ways to enrich diets with nutrients. Organic fertilizers confront the issue of extending the duration of nutrient release and decreasing mineral content; however, inorganic fertilizers suffer from volatilization and loss of leaching. Nanotechnology’s application in agriculture has enormous promise to address these issues. The use of nanoparticles in biofortification of wheat is gaining traction due to their capacity to provide the optimal amount of fertilizer at the optimal time, hence reducing environmental concerns, facilitating nutrient uptake and absorption, and increasing grain production and profitability. Wheat is a major field crop that can solve with applying nano-biofortification the problem of malnutrition and nutrient deficiencies in humans. Although numerous research experiments on nano-bio-fortification of wheat plants have been conducted, this review article summarizes the benefits and results of nano-bio-fortification for grain maximization through a comprehensive review of nanomaterials and fertilizers and their effective role in bio-fortification and grain yield maximization. Moreover, current trends in the usage of many nanotechnology-based biofortification methods for wheat production were highlighted. Several methods for wheat improvement, including macro and micronutrient supply, are reviewed in more details. Understanding several features of the safe use of nanoparticles and their future prospects may assist in their effective use in terms of economics and nutritional needs after the usage of nano-fertilizers and nano-biostimulants in biofortification and wheat grain yield maximization.
