|Goal and objectives of the project
- To synthesize metal nanoparticles Fe, Cu, Co, ZnO with size 40-100 nm and silver nano solution with concentration from 100 - 500 ppm.
Metal nanoparticles were synthesized with corresponding sizes: iron nanoparticles with sizes of 40-100 nm; copper nanoparticles - 10 - 70 nm; Co nanoparticles - 50 -100 nm. The ZnO nanoparticles prepared by sol-gel method has a small, uniform spherical particle size. The ZnO nanoparticles size is concentrated in the range of 10-50 nm. The fabricated ZnO nanoparticles has a rather high surface area, a certain porosity and an average pore diameter. The content of Zn and O in the fabricated samples was determined to reach 86.75% by mass. Besides, solution of silver nanoparticles was successfully synthesized with the average size in the range of 5-20 nm, uniform particles with little cohesion. The average size of particles in the range of 44 nm by DLS analysis method and zeta potential in the range of 33mV. The results showed that the synthesized samples have similar grain sizes as well as zeta potential, so the repeatability of the fabrication process is highly stable.
|Novelty and actuality and scientific meaningfulness of the results
The obtained results of the study showed that the treatment of wheat and barley seeds with metal nanoparticles and metal oxides had a positive effect on the growth of wheat and barley seedlings (increasing stem height of wheat, barley plants). The nano-preparations also showed antifungal activity against phytopathogenic fungi, reduced the infection rate of wheat and barley grains, increased the synthesis of photosynthetic pigments and inhibited membrane lipid peroxidation, and increased the average mass of stems by 20–60% and ear mass by 20–50%. The results can provide a promising economical and environmentally friendly presowing treatment with ultra-low concentrations of metal nanoparticles.
|Products of the project
With the positive results obtained from the research of the Belarusian partner group during the cooperation process, it is possible to see the prospects for the development of nanotechnology applications in seed treatment before sowing on many different crops, in both Vietnam and Belarus. Both research groups need to continue to build larger-scale studies, as well as carry out more in-depth goals and contents to elucidate the mechanism of metal nanoparticles to plants, plant cells and phytopathogenic fungal cells. In addition, the Vietnamese side needs to rely on that to conduct research and application on domestic plants, for example, wet rice in our country.
