AI-Generated Summary

Nanotechnology involves manipulating matter at the atomic and molecular scale (1–100 nanometers) to create materials and devices with unique properties. It has transformative applications across industries, including healthcare (drug delivery, diagnostics), electronics (smaller, faster devices), energy (efficient batteries, solar cells), and environmental remediation (water purification, pollution control). Challenges include potential health and environmental risks, ethical concerns, and high development costs. Despite these, nanotechnology is advancing rapidly, driven by interdisciplinary research and innovation. Its potential to revolutionize technology and improve quality of life makes it a critical field for future scientific and economic growth. Collaboration and regulation are essential to ensure its safe and sustainable development.
