( UPPSC, UP PCS Mains General Studies-III/GS-3 2022)
Answer.
Nanoscience is the study of materials at the nanoscale ( 1* 10^-9 m). It includes the study of materials of size between 1 and 100 nanometers in size.
Nanotechnology involves designing, producing, and applying materials and devices at the nanoscale.
Nanotechnology can potentially revolutionize many fields of science including medicine, agriculture, electrical, and electronics.
In agriculture, nanotechnology is used for the efficient delivery of plant nutrients, pesticides, and water efficiency, it is also used to monitor the moisture and growth of the nanoscale. So, nanotechnology is used to enhance crop yield, improve plant nutrition and protection, and reduce environmental pollution.
The following are some applications of nanoscience and nanotechnology in agriculture;
Nanoparticle; Nanoparticles can be used to deliver fertilizer and pesticides which will help to minimize the chemical needed and minimize environmental pollution.
Nano-sensors; Nano-sensor can be used to detect soil conditions, plant growth, and disease, which will help in the planning and application of fertilizer and pesticides.
Nanofilters; Nanofilters can be used to remove pollutants from water, improving water quality, and reducing environmental pollution.
Nanotechnology is able to produce lighter and more durable instruments at lower cost. The following are the potential of nanotechnology in the field of science;
In the field of renewable energy, nanotechnology can make lighter wind turbines, which can improve fuel efficiency and enhance electricity generation with slow wind blowing. Nanotechnology has the potential to double the electricity generation by solar cells by using carbon nanotubes.
The use of lightweight materials in the field of electrical and electronic equipment will reduce fuel costs, which will reduce greenhouse gas emissions.
In the field of science like the medical field, the following are the use of nanoscience and nanotechnology in medicine;
Targeted drug delivery; Nanoparticles can be used to target specific cancer cells, which will allow more effective treatment with fewer side effects.
Repair of damaged cells; Nanotechnology can be used to create scaffolds for tissue regeneration.
Nano-Biosensor; Nano-biosensor can be used to detect disease markers in the body, which will help early detection and treatment of disease.
In conclusion, we can say the application of nanoscience and nanotechnology is vast and has many applications in many different fields of science and agriculture.
