  • Reduction of pollution: By using smaller amounts of fertilizer and improving its efficiency, nutrient runoff into water bodies is reduced, minimizing eutrophication.
  • Higher Yield: Better nutrient absorption leads to higher crop growth and yield.
  • Cost reduction: Less fertilizer use and higher absorption efficiency translate into economic savings for farmers.

Nanopesticides: More sustainable pest control for safer agriculture

Nanopesticides represent another crucial application area. These nanoscale pesticides can more precisely target pests and diseases, reducing the total amount of pesticide needed and therefore decreasing chemical residues on crops and the environment. The nanoparticles allow the pesticide to target the pest directly, minimizing the impact on the environment and protecting pollinators and other beneficial organisms.

Advantages and benefits of nanopesticides:

  • Targeted Application and Greater Precision: Nanoparticles can be designed to specifically adhere to the surfaces of pests or pathogens, increasing the effectiveness of the pesticide.
  • Lower Environmental Toxicity: By requiring lower doses, nanopesticides reduce the amount of chemicals released into the environment. Additionally, they protect the pesticide from environmental degradation, reducing its toxicity to the environment and non-target organisms.
  • Extended Duration: Many nanopesticides offer slow release, which prolongs their effectiveness and reduces the need for frequent applications.
  • Greater effectiveness: The controlled release of the pesticide ensures greater effectiveness in pest control.
  • Pollinator protection: Nanoparticles minimize the impact of the pesticide on pollinators and other beneficial organisms.

Nanodevices and nanosensors for monitoring and diagnosis
