Nanotechnology is one of the most impressive sciences in the twenty-first century. Not surprisingly, nanoparticles/nanomaterials have been widely deployed given their multifunctional attributes and ease of preparation via environmentally friendly, cost-effective, and simple methods. Although there are assorted optimized preparative methods for synthesizing the nanoparticles, the main challenge is to find a comprehensive method that has multifaceted properties. The goal of this study has been to synthesize aminated (nano)particles via the Rosmarinus officinalis leaf extract-mediated copper oxide; this modification leads to the preparation of (nano)particles with promising biological and photocatalytic applications. The synthesized NPs have been fully characterized, and biological activity was evaluated in antibacterial assessment against Bacillus cereus as a model Gram-positive and Pseudomonas aeruginosa as a model Gram-negative bacterium. The bio-synthesized copper oxide (nano)particles were screened by MTT assay by applying the HEK-293 cell line. The aminated (nano)particles have shown lower cytotoxicity (~ 21%), higher (~ 50%) antibacterial activity, and a considerable increase in zeta potential value (~ + 13.4 mV). The prepared (nano)particles also revealed considerable photocatalytic activity compared to other studies wherein the dye degradation process attained 97.4% promising efficiency in only 80 min and just 7% degradation after 80 min under dark conditions. The biosynthesized copper oxide (CuO) (nano)particle’s biomedical investigation underscores an eco-friendly synthesis of (nano)particles, their noticeable stability in the green reaction media, and impressive biological activity.

“…Likewise, the seed soaking with nanoparticles solution has shown improvements toward increased and more stable production [98]. In order to use nanoparticles in a clear legislative framework, it is necessary to synthesize them with an innovative composition as well as similar in their properties as much as possible to natural substances [99]. In this context, nanofertilizers synthesized by the bio-method are promising substances for achieving sustainable growth of crop yields and securing food for the ever-increasing population [79].…”

“…The soil is a system full of life, particularly symbiotic associations with the roots of different plant species [99]. Plants exchange gas and fluid with the environment via their leaves and roots, where rhizosphere microorganisms (rhizobacteria and mycorrhizal fungi) solubilize minerals and then the plants absorb solubilize nutrients [100].…”

Nanotechnology can change agricultural systems and methods used via nanofertilization. It contributes to reducing pollution, protecting the environment, as well as reducing the costs of using chemical fertilizers. Nanofertilizers provide soluble nutrients that are quickly absorbed and reduce their build-up in the soil. Also, it increases plant growth and development and enhances plant resistance to biotic and abiotic stresses. Nanofertilizers' effect on plants varies according to the plant type, method of application, and the size and concentration of different nanoparticles. Moreover, it is necessary to highlight their adverse effects related to toxicity. In addition, we will discuss the future prospects for the use of nanofertilizers.
Mechanisms of the effect of nanofertilizer in:
1- Plant growth and development
2- Crop yield
3- Soil fertility
4- The relationship between nanofertilizer and stresses
5- The role of nanofertilizer in environmental protect
6- Toxicity of nanofertilizer
7- The future prospects
