What are the applications of nanotechnology?

Nanotechnology has many applications; to list a few:

• Development of new therapies and drugs to treat human diseases
• Cosmetics
• Food science (E.g., shelf-life extension)
• Electronics (E.g., build precise circuits)
• Solar panels that generate more energy
• Industry (E.g., creation of smart fabrics)
• Biofuels (E.g., cellulose conversion from wood chips, corn stalks, unfertilized perennial grasses for fuel).
• Environmental remediation (E.g., to clean industrial water pollutants)
• Transportation (E.g., lightweight, high-strength materials applied to vehicles).
