In our modern world, there is a direct association among the increased population and the invention of massive volume of waste which might be degradable of high moisture content, making them ideal substrates for the production of organic fertilizers that play as suitable substitutes for chemical fertilizers and could protect the environment. Eco-fr...
New drug delivery strategies have become a pioneer and novel approach in controlling plant diseases in application research nowadays. In this paper, we investigate the delivery of chitosan nanoparticles (CSNPs), carbon nanotubes (CNTs) and solid lipid nanoparticles (SLNPs) loaded with nystatin (NYS) and fluconazole (FLZ) antifungal antibiotics for...
Salinity stress can significantly cause negative impacts on the physiological and biochemical traits of plants and, consequently, a reduction in the yield productivity of crops. Therefore, the current study aimed to investigate the effects of chitosan (Cs) and chitosan nanoparticles (CsNPs) to mitigate salinity stress (i.e., 25, 50, 100, and 200 mM...
Through interactions with plant cells, silver nanoparticles (AgNPs) with both biological and chemical origins can stimulate physiological and metabolic processes in plants. To ensure their safe application in the food chain, it is necessary to investigate their effects on plant systems. Therefore, the effects of chemical AgNPs (chem-AgNPs) and biol...
Engineered nanoparticles have enabled the development of novel uses, particularly in disease management. In this investigation, we synthesized and studied three distinct nanomaterials: solid lipid nanoparticles (SLNPs), chitosan nanoparticles (CSNPs), and carbon nanotubes (CNTs), either alone or loaded with two antifungals, nystatin, and fluconazol...
The present study was conducted to evaluate the effects of silicon (Si) and nano-silicon (NSi) on growth, yield, ions content, and antioxidant defense systems, including transcript levels of enzyme-encoding genes in Pisum sativum plants grown under salinity stress. Both Si and NSi were applied at the 3 mM level and NaCl was applied at 4 concentrati...
Human activities all over the world cause many changes in the environment. These changes resulted in more complicated challenges facing all living things on earth. Among these challenges are abiotic stresses, particularly salinity and drought, which contribute to the huge crops yield loss around the world, thereby leading to food insecurity issues....
This study was designed to investigate the potential of using carbon nanotubes (CNTs) either alone or loaded with urea and peat moss to reclaim sandy soil. A pot study (over 3 seasons) was designed in which bean seeds were planted in sandy soil either alone or amended with different concentrations of urea, peat moss, and multi-walled carbon nanotub...
The increase in population all around the globe has led to major problems including the concerns related to supply of good quality food for such ever growing population. Nanotechnology has entered every aspect of day to day life and made huge breakthrough results. In agriculture, nanotechnology is still under deep research and provides pioneer solu...
Waste generation is a global issue that necessitates effective management for both human and animal health as well as environment. There are several ways to reduce waste, but recycling appears to be the best choice. By recycling, not only will the problem of pollution be resolved, but valuable compounds could be generated to be used as nutrients fo...
The potential of nanotechnology is for innovation in the agricultural and food industries. Different nanosensors types are being created to satisfy the varying agri/food industry demands, comprising food components, smart packaging, and rapid detection systems. It is necessary to understand the assigned mechanisms or causes for nanoscale toxic impa...
Recently, nanotechnology has started to revolutionize all agricultural practices. Nanotechnology research has improved all aspects of current agriculture. It can enhance the growth of plants by improving uptake of nutrients through engineered nanofertilizers. Also, it plays a pioneer role to monitor plant and soil conditions through nanosensors and...
Nanotechnology leads as a pioneer technology in all science areas. It opens up a broad range of possibilities in different areas such as medicine, pharmaceuticals, electronics, and farming. Nanotechnology’s potential for revolutionizing healthcare, textiles, equipment, data and communication technology, and energy industries has been well publicize...
The present study aimed to compare the ability of Conyza bonariensis and Amaranthus viridis to accumulate macronutrients: nitrogen, phosphorus, potassium (NPK) and trace elements (TEs) in their underground and aboveground tissues from the soils in the mining areas. The plant parts and their soils were collected from three sites (El-Gedida mining or...
This investigation was planned to utilize chemically synthesized silver nanoparticles (AgNPs), as a priming agent,
for improving the germination of aged Vicia faba seeds. Application of AgNPs (0, 10, 50 and 100 ppm) to Vicia faba
seeds led to distinctive endpoints indicating a reduction of aging-related genotoxic impacts at both cytological
and phy...
Nanotechnology has become a solution to most of the problems facing humans nowadays. In agriculture, nanofertilizers play a pioneer role to enrich crop productivity and minimize environmental pollution problems. In this paper we investigate the possible effects of using two engineered nanomaterials nanochitosan (Cs) or carbon nanotubes (CNTs) eithe...
This study was conducted to explore the effects of priming of seven-year-old aged seeds with different concentrations of silver nanoparticles (AgNPs) on growth of broad bean (Vicia faba L.). Seeds were primed with different concentrations of AgNPs for 6 h before growing in the plastic trays. Different growth parameters like growth attributes, photo...

Carbon nanotubes either single-walled or multiwalled have been a focus in materials research. Carbon nanotubes are tubular structures of nanometer diameter and large length/diameter ratio. The nanotubes may consist of one, tens and hundreds of concentric shells of carbons with adjacent shells separation of ˜0.34 nm and they can have different indiv...
Salinity is considered a hindrance for growth and productivity of several economic crops worldwide. In this paper we investigate the effects of different concentrations of NaCl (0, 25, 50 and 100 mM) on growth and gene expression of two tomato cultivars differing in salt tolerance, a salt sensitive variety (GS12) and a salt tolerant cultivar (Adora...
The application of nanomaterials in agriculture is one of the most greatly studied areas in nanotechnology as it includes the using of nanofertilizers to transport nutrient elements to the plant at the needed time and required amount, thereby improving the use efficiency.
