3. Question
Which of the following areas where Nano-Technology can be used?
1. Textiles
2. Agriculture
3. PlasticsCorrectAns;- d) All of the above
Explanation;-
• Applications of nanotechnology have emerged with increasing need of nanoparticle uses in various fields of food science and food microbiology, including food processing, food packaging, functional food development, food safety, detection of foodborne pathogens, and shelf-life extension of food and/or food products.
• The properties imparted to textiles using nanotechnology include water repellence, soil resistance, wrinkle resistance, anti-bacteria, anti-static and UV-protection, flame retardation, improvement of dye ability, Self-cleaning fabrics and so on.
Nanotechnology can increase agricultural production, and its applications include:
• (1) nanoformulations of agrochemicals for applying pesticides and fertilizers for crop improvement;
• (2) the application of nanosensors in crop protection for the identification of diseases and residues of agrochemicals;
• (3) nanodevices for the genetic engineering of plants;
• (4) plant disease diagnostics;
• (5) animal health, animal breeding, poultry production; and
(6) postharvest management.
