According to a recent scientific research published in the Science Report of the British magazine Nature, in addition to humans, medical nanoparticles for drug delivery can also help treat nutritional deficiencies in crops, which will help the agricultural production sector Increase crop yields.
In the past few decades, the advantages of liposomes as an advanced nano drug delivery system have been recognized by more and more people. In fact, a liposome refers to a microvesicle formed by encapsulating a drug in a lipid-like bilayer, which can pass through a biological barrier and deliver a drug or other substance filled therein. Target organization. They have been shown to be effective in delivering drugs for the treatment of diseases such as cancer.
Since such nanoparticles have good biocompatibility and can be normally metabolized, their development potential as a carrier is enormous. This time, Israeli Institute of Technology researcher Ivey Schroeder and colleagues tested the ability of nanoparticles to deliver nutrients to seedlings and fully grown cherry tomato plants. The research team treated the magnesium-deficient and iron-deficient plants in two ways, one is a nano-particle loaded with magnesium iron, and the other is industrial magnesium and industrial iron not contained in the nano-particle.
Experiments have shown that nanoparticles treated plants overcome acute nutritional deficiencies that are not treated by standard agrotrophic nutrients; after 14 days of application, the nanonutrient-treated nutrient-deficient plants restore health, while plants treated with standard agrotrophic nutrients do not.
The researchers said that the nanoparticles will spread throughout the leaves and roots of the plant, and then be taken up by the plant cells, where nutrients are released. The results of this study show that nanoparticles not only change the diagnosis, treatment and prevention methods of many diseases, but also apply nanotechnology to agricultural production, which is also expected to increase crop yield.
